Wireless Connectivity on DoD Bases with a Private 5G Network Business

Benefits of Private 5G networks for military bases and installations,Author: Jennifer Goforth Gregory,5G is providing secure, high-performance solutions, like private 5G networks, that can integrate seamlessly with legacy systems and help enable the Department of Defense (DoD) to transform and support mission readiness and . Military bases and installations require reliable, secure, and available public infrastructure that can support needs of every person on the base—military and civilian. However, many factors make it challenging, if not impossible, for the current, often aging, infrastructure to meet bases' evolving needs. The focus by leveraging 5G solutions, including private 5G networks, to address these needs. The challenges of network management on base,The network maturity for military bases is one of , with some bases equipped with the latest hardware and physical infrastructure, while others face outdated technology and facilities. Military installations and bases that use old hardware and aging cable plant operations desperately —which can take years and a significant investment. And there are certainly bases with a mix of new and old technologies. Regardless, each base must continue to serve its missions and support its employees and residents, regardless of its current state of infrastructure. Military services,DoD personnel from other bases make frequent visits for meetings and special projects creating even more situations that need access. Even bases with updated infrastructure encounter issues trying to manage security and flexible network access across the entire base ecosystem–outdoors, indoors, and remote. The shift to remote and hybrid work makes providing a secure and easy-to-use experience even more challenging. Federal workers support , including the flexibility to work in whatever location works best for their tasks and current needs, be it on or off base. In addition to some people working from home, others find that working in another building on the campus or even another agency improves collaboration or productivity—often both. However, bases find it increasingly difficult to provide the seamless experience and reliable connectivity employees need and expect. Civilian services,Many bases also support civilian services like banks, restaurants, schools, businesses, and other facilities which all require secure network to support the community. need connectivity, which can put bandwidth restraints on bases, to conduct their day-to-day lives, including their personal needs, lifestyle and even entertainment. The addition of unmanaged personal and can also present security concerns as it creates additional opportunities for bad actors to access the network. Disparities between bases,Military bases and their communities vary greatly in size, population, and location. For example, there are bases that are less than 30 acres in size yet nestled right in a cityscape, providing its service members and their families an urban setting just off base. There are also expansive bases, which encompasses almost 600,000 acres yet are located in a desert region. This variety of geographic coverage and locality constrains the available budgets, resources, and supply chains to provide and upgrade network footprints. Expanding this consideration to take account for the global presence of the military and related national security needs, resilient, scalable, and secure networking capabilities become even more critical. Both large and small communities can face unique problems imposed by coalition training and increased foreign national presence on base, in addition to the other challenges outlined. Providing flexible and secure wireless network capabilities to help solve these problems is key for base operational success, and embracing private 5G can help address many of these problems. Network optimization can help support complex needs,Many times current local area network (LAN) environments simply do not satisfy the for network optimization on its own. According to Robert Bowers, Principal Architect for Verizon and a Marine Corps veteran, "The state of base networks across all service branches reflects a complex array of independent approaches and technology sets. Each base has historically been responsible for their own maintenance, often occurring on an irregular basis or only when critically needed. With the recent advancements in network security and wireless technologies, enterprises have become very interested in delivering secure and compliant environments untethered from the office cubicle. Many commands within the DoD hold these same aspirations.",The evolution of military bases includes more geographic inclusion of remote training areas and flight line operations, which often means unreliable coverage with dead zones and other areas with little-to-poor coverage. Additionally, the costs for wireless coverage for large base facilities with multiple buildings and locations can be significant. While Wi-Fi has traditionally served well for indoor environments, Wi-Fi poses significant limitations for extending network access beyond building walls, restricting base users from complete access. Managing these situations with traditional wireless and wired networks can be inefficient at times, especially with extending service to larger, outdoor areas. Referencing situations like these, Bowers discussed how innovative 4G LTE and 5G solutions can reliably provide network backhaul or redundant backup capabilities, in addition to supplementing signal shortcomings of Wi-Fi solutions. Private 5G networks improve security, productivity and connectivity,Private 5G network deployments offer enhanced network management options including all the capabilities and benefits of public 5G service, but with added security of being able to prohibit unintended users/devices from existing on that private network segment. Bases that employ private 5G networks can choose from multiple options to provide the highest level of performance and experience based on the base's configuration and needs. Bases can deploy a private 5G network using many different transition approaches to suit their fiscal or network needs, such as preserving any existing private 4G LTE assets to migrate to a standalone 5G system later, or deploying a non-standalone 4G LTE and 5G solution in tandem. With a private 5G network access solution, base network administrators can address problems with network congestion that can disrupt productivity and network speeds at bases. Additionally, a private 5G network can help prevent or unauthorized network scanning. Bases can also acquire enhanced network reliability and ultra low latency capabilities for endpoints beyond personal use devices–such as security sensor and IoT devices. For example, a 5G-enabled solution can make it possible to enhance through network management. Base commands are charged with ensuring both physical security and cybersecurity of the hangars and physical equipment, to include logistics and maintenance assets in addition to aircrafts. Effective flight line operations rely upon ubiquitous connectivity for sensor networks, mobile devices, and computer networks to enhance maintenance and supply activities, and subsequently improve the overall mission readiness of the squadron. With 5G, connectivity can be extended beyond wifi-enabled hangers, while also inheriting other benefits like unified network management where data from the IoT sensors can feed into logistics or flight-kit applications in near real-time. Bases planning for infrastructure upgrades can use private 5G networks either to supplement their existing LAN or replace it. By combining 4G LTE or 5G capabilities into Base Area Network designs as part of network management, you can connect geographically separate facilities more cost-effectively than lengthy copper/fiber-based LAN extensions with Wi-Fi. With the rapid development of feature enhancements and network improvements, integrated 5G systems can contribute to faster bandwidth speeds and consolidated management of digital ecosystems, which fundamentally helps improve the performance and efficiency of assets and services. For larger bases that have thousands of users, private 5G networks offer digital environments which support increased endpoint density, offering easier, consolidated means of managing access across the diverse portfolio of end-user devices and IoT sensors of today and the future. The role of traffic management in 5G network optimization,In addition to ensuring reliable, secure, fast connectivity throughout the base, 5G systems also help address a constant network optimization challenge for base IT leaders—traffic management. While it's important that everyone has access, all connections and data sent over the network are not equal in terms of priority and security. A fast food order, for example, should not be treated the same as a critical conference call. Expanding upon traffic management, Bowers also discussed network slicing and quality of service (QoS) flows with respect to 5G systems. With a private 5G network, end-to-end can offer traffic segregation and prioritization as part of the traffic management strategy. For example, network slices can be provisioned to segregate traffic flows by device type, where traffic involving latency-sensitive applications can hold a separate network slice from internet traffic from a logistician's tablet. Priority can also be prescribed (and preserved end-to-end) by application, such as real-time security camera feeds over non-critical conference calls. For 5G deployments that supplement existing IP network environments, network slices and their QoS flows can be mapped to IP-based quality of service (QoS) policies across the BAN, effectively preserving end-to-end traffic management features across multiple domains. How to benefit from private 5G networks at DoD bases,Private 5G networks offer distinct benefits to help everyone who steps on the base regardless of their job or duties, instead of worrying about connectivity. With current performance and access demands steadily rising, DoD bases and installations need to embrace innovative capabilities and solutions to not only address current problem sets, but also to remain appropriately positioned to meet the needs of the service member community and the future. 5G private networks enable enhanced user experiences, delivering secure environments coupled with the flexibility and freedom of movement realized on many campuses today.

What is a Wide Area Network (WAN)?

What is a Wide Area Network (WAN)?,It's about good connections for your growing application demands. Like your most goal-driven team members, data needs a clear path and the right clearances to cross the finish line. A wide-area network (WAN) is your data's highway across the digital landscape. It provides an avenue between your digital resources, such as hardware and software, and your users. Your data is like your users on the network, with things to do and places to go. If the road users take (your WAN) is pitted, narrow, gravely and single lane, the trip will be slow and possibly hazardous. If the road is a modern thoroughfare, the ride will be smoother, faster, more direct and safer. WANs that work well are built for reliable, high-impact communications. They allow businesses to route data — efficiently and cost-effectively — to and from users and sites, near and far. Just as with roads, WANs come in many configurations. Understanding some of the architectural key points can help inform decisions about your network investments. What does WAN mean, and what does it do?,A WAN is little more than an organized set of internet protocol (IP)-based connections that allows you to move data among distributed teams and devices. When you send personal emails, videos, images or text, the data files are generally simple and small enough to edit, save and share electronically. But things can get complicated when the connections that move this information multiply to accommodate more employees, office locations and cloud- or server-based applications. WANs are controlled-access telecommunications systems that are designed to efficiently transmit larger amounts of data, enabling network connectivity to a wide area. That area might be geographical, as with field offices, high-capacity in terms of processing power and users, or both. What are the advantages of WAN over LAN, and what's the difference?,If your business operates out of your home or a small leased space, you've probably linked together a couple of computers, a printer and a router/modem combination to get online. You also probably have a physical (usually Ethernet) or Wi-Fi link. This is a local area network (LAN) configuration. As your business grows, you need more bandwidth to handle more types of files more quickly and securely across greater distances. A WAN is usually the network that ties local systems together. With a WAN, your LANs and teams can connect to companywide databases and tools that facilitate conferencing, marketing automation, customer relationship management (CRM) and other business operations — all of which are beyond the LAN's scope. How does WAN work?,WANs can use different types of connectivity and technologies to bridge their various parts. WAN operators often employ virtual private networks (VPNs) to interconnect locations and devices more securely. A virtual private network is important because data handled by IP-based WANs may become vulnerable as it moves across the internet. As businesses grow, many are faced with aging network infrastructure and convoluted architectures resulting from technologies that were added over the years. To boost productivity and profitability, they may need WANs that use both wired and wireless technologies. Yet implementing both may seem impossible given available budgets and limited technology resources. And businesses may put off potentially game-changing advancements because they are fearful of the risks and costs to their network. Hybrid, wired and wireless networks can lead to delayed or flawed security updates and implementation of business-critical applications. Think of the work involved in retrofitting equipment, alone. Settings must be changed for routers and servers. Phones, laptops and tablets may need new setups. They may even need to be replaced. Software defined wide area network (SD WAN) technology may be the answer to these challenges. What is SD WAN, and how can it help growing businesses?,Software-defined networks (SDNs) are gaining traction because of their usefulness in surmounting complexity and cost obstacles associated with hybrid networking and cloud computing. To streamline disparate networks while getting the most out of pricey bandwidth, more businesses are turning to a type of SDN called . Among its advantages, SD WAN allows businesses to control several network components and processes from a single interface or computer dashboard. SD WAN is hosted and based in the cloud, and is useful for businesses with branch offices and remote employees using a variety of networking methods. Additionally, SD WANs can eliminate many manual operations and the need for expensive circuits to interconnect hybrid networks. At the same time, the technology makes it easier to maximize bandwidth in near-real time. This means that lower priority activity, such as web-surfing for noncritical work, can be sent through inexpensive public IP channels. More expensive circuits can be reserved for mission-critical and sensitive activity involving sales transactions and customer databases. One way to think of SD WAN is to picture vehicles at an intersection on a divided highway. The network's routing mechanisms are like the traffic lights. The drivers are going one way or the other, and taking turns based on the traffic signals. With SD WAN, instead of a traffic light that doesn't respond immediately to changing conditions, you now have a sort of traffic-management genius in control. This highly trained professional uses advanced tools to evaluate traffic flow, vehicle occupancy and other qualitative factors to determine whether the light is red or green in a given direction. Like this pro traffic manager, SD WAN green-lights important, delay-sensitive payloads. Others get the red light, or are routed elsewhere. Everyone gets through the intersection efficiently and safely, relative to their situation and cargo. Are you ready to move from a LAN to a WAN?,If so, you have plenty of options that can meet your needs. Our networking experts can help you evaluate your requirements and find a solution that fits your budget and ambitions.

If you'd like to receive new articles, solutions briefs, whitepapers and more—just let us know. Wherever a company is on its Digital Network Transformation journey, enterprises can benefit from technical and operational insights. Common formats include reference architectures, adoption challenges, potential barriers and key areas for consideration. Detailed descriptions of technology used, as well as explanations of how Verizon applies and integrates technology and network management platforms, are provided throughout this document. Some of the key takeaways are:With time, resources and effort, enterprises might be able to do this themselves. However, for a time and resource-constrained IT team, the good news is that a digital network technology refresh need not be complex or time-consuming to deploy or manage. Low-touch provisioning significantly reduces the deployment delays and expense associated with manual turn-ups. Automation and consolidation of policy management means more effective use of limited operational resources, and integrated management tools means optimal uptime and performance in production. Recognized for innovation, Verizon is not waiting for the future, we are building it! Are you ready to join with us in taking the next steps in your digital network transformation journey?While there are no shortage of signs that delaying an update might potentially lead to detrimental effects on realizing business objectives, enterprises exploring Digital Network Transformation initiatives are finding few common industry standards or best practice models for their projects. A new era of digital business has arrived where organizations must seek ways to apply technology and applications as a means of meeting customers, business partners, and staff expectations. The ability for enterprises to expedite a digital transformation will play a large role in the success of securing a growth position in the new, global, digital marketplace. The pace of change is only accelerating further with the arrival of 5G, Multi-Access Edge Computing (MEC), SD WAN, virtualized networking services, and other new technologies on the networking side, and Edge Computing, IoT and Artificial Intelligence (to name a few) on the application side. Enterprises are now faced with "always-on, always connected, always performing" application and network expectations from staff and customers. Traditional network deployments are challenged to keep up, making it even more difficult for IT managers to be successful. The data explosion, combined with increasingly higher user expectations, has been driving technological change at an incredibly fast pace. IT managers are forced to rethink their network strategy – not just the hardware and the software, but the skill sets their staff need to support it. "Digitalization" is possibly an overused term, but this is the environment we are operating in today. Challenges for traditional WAN architectures also include:,As many enterprises are finding, traditional networks were not designed to optimize (or even be aware of) application performance. They have been complex and cumbersome to manage and maintain, often having been designed for and built on purpose-built proprietary, network equipment such as routers, Ethernet switches, firewalls, and load balancers. Deploying these monolithic network elements has meant long development and installation cycles, overly complex lifecycle management (adding to operational inefficiency and overhead), and increased need for investment in upgraded equipment, often at a rate that exceeds revenue growth. Often, existing enterprise networks are composed of "bundled" vendor proprietary network elements where the control, management, and data (including user data traffic) functions are physically tied to the network functions themselves. Deployment of new services or modifications to existing services must be done on an element-by-element basis, requiring tight coordination of internal and external resources. This traditional approach limits the ability to tune network operational flexibility and application awareness and potentially forces IT managers into a risky strategy of reliance on proprietary vender point solutions. Verizon's investment in SDN means less reliance on vendor proprietary solutions and more flexibility to incorporate new technologies as they develop. There are significant challenges to be aware of before undertaking a DIY (Do It Yourself) network transformation project. There are many factors that may need to be changed to support a digital network transformation to a SDN network architecture. Following are some common issues that should be considered and addressed:,Digital Network Transformation offers a better way to deliver and manage networks that support public cloud, IoT, and other exciting applications that are driving modern business in new directions. It really is the time in the networking world to use software-based assets as opposed to physical assets because software based assets have the ability to better integrate the network with digital applications. The Verizon SDN product portfolio has been designed from the ground up as a business enabler in the digital world. Through a "Network-as-a-service" consumption model working at "cloud speed," Verizon SDN services leverage many available connectivity types to help organizations maximize network technology investments. Quite simply, Verizon SDN services provide the same type of scalable, consumption-based experience you would expect when provisioning virtual computing resources from a hyper-scale cloud provider. Through a combination of automated delivery and orchestration of pre-tested and verified solutions bundles, whether on premises, hosted, or any hybrid mixture, Verizon stands by its ability to enable you to realize the most from your existing network resources, create a fluid foundation for the future, and evolve with future technology and business changes. Figure 1: Verizon Virtual Network Services Ties Networks and Applications Together,Let's step back for a moment to see how Verizon came to build this powerful portfolio of SDN services. For the enterprise, knowing that Verizon is leveraging and contributing to the development of standard Digital Network Transformation methodologies offers peace of mind because there is consensus across the network service delivery and vendor communities. Verizon is a founding member and a current Board Member of the Open Network Foundation (ONF), the industry organization that develops global standards for Software Defined Networking, as well as the Linux Networking Foundation (LFN) - both pre-eminent bodies focused on the development of standards in support of virtualized networking. Verizon has based its SDN-NFV product suite goals on established Open Source principles:,The following are key features of networks based on SDN and NFV principles:,Combining these principles and concepts facilitates dynamic network adaptations based on application performance requirements, increases operational flexibility, and simplifies service development. Functions may be dynamically scaled to meet fluctuations in demand. Future developments will incorporate autonomous functions with sophisticated analytics and artificial intelligence technologies. Digital Network Transformation is still in the early stages of adoption. Many organizations have not yet considered, or are still just starting to consider, undertaking a transformation project. There are great benefits as well as barriers to SDN/NFV adoption. As enterprises learn more about the technology and come to better understand the benefits, the number of field deployments will continue to grow. The benefits of Digital Network Transformation include:,Reasons an IT manager might consider a delay include:,An understanding of the financial impact of delaying a digital transformation with newer agile technologies is a commonly ignored variable and critical to keeping ahead of competition. Do It Yourself (DIY) transformations might initially appear to be a cost-effective and efficient option. However, working with a partner (service provider or integrator) who has experience with global digital network implementations, as well as the full breadth of lab and support resources to test, collaborate with disparate technology vendors, and manage a project at scale, can mean the difference between the success or failure of a digital transformation project. We live in an unpredictable world. With the pace of change accelerating, there is a need to be able to respond quickly to realize short-term opportunities and deliver new services to market ahead of the competition. Whatever the reasons for needing network flexibility, the expectation is that a responsive system should be easy to achieve and that IT should be able to support it. However, while users and applications are dynamic, traditional Wide Area Networks (WAN) were never designed to support such rapid change. They were designed for a world where the enterprise perimeter was fixed. When additional capacity was needed, it had be planned for in advance. When the instantaneous, elastic nature of cloud collides with the fixed, rigid wide area network, applications potentially suffer performance problems. This, in turn, impacts the user experience and potentially has a negative effect on brand and reputation as well. Enterprises should understand the need for more flexible and agile networks to be able to adapt quickly in a fast-changing environment. However, the process for enterprises to implement software-defined solutions can often be hindered by budget constraints, a lack of skills, and other business priorities. Lack of skills in particular can be a significant obstacle for enterprises from the very beginning of their network transformation journey. Four key elements are necessary for a successful transition to an agile, adaptive Digital Network Transformation:,Verizon built Virtual Network Services (VNS) on the OpenStack platform, a widely accepted cloud platform used in the Telecom industry for supporting VNFs, using containerization for further efficiencies. Since VNS is available in several options (hosted, public cloud, premise-based or purpose built), you can build the network that is the best fit for your requirements while still being able to take advantage of shortened development times for new features and services. VNS has the ability to rapidly deliver a broad array of best-in-class network technologies from trusted global leaders as well as industry innovators, dramatically reducing sourcing, contracting, and deployment cycle times. In addition, automated solutions bundles accelerate provisioning by delivering multiple services together instead of sequentially, shortening the time to realize value while making digital transformation through SDN simple. The nimble nature of VNS provides the elasticity necessary to meet evolving demands and expectations based on business need. The real value of using Verizon's VNS SDN portfolio is the ability to use pre-defined automated, proven, and tested solutions bundles. For example, each instance can be tailored to different requirements of various types of branch sites or hub sites. For example, some sites may need WAN optimization and others not. By using solutions bundles, Verizon can deploy the services that are needed using our automated deployment and management, while allowing you to retain control of the policies and the ability to make changes as business requirements dictate. Rest assured that whatever solutions bundle you choose, Verizon has performed extensive lab testing to ensure that what occurs in the lab environment matches what you will experience in a live WAN production environment. Verizon's lab testing creates an exceptional result for customers as it is designed specifically to dig into the performance characteristics of the features of the integrated solution using the typical customer traffic profiles that will occur in the actual user environment. You can have confidence in that we have verified that the solutions bundles you receive from us will perform as they were intended. In practice this means:,Figure 2: Virtual Network Services platform optionsFigure 3: Virtual Network Services deployment options,Regardless of the deployment model chosen, you can derive return on investment, not just from the control of capital expenditure on hardware, but also from the reduction of "soft costs" associated with managing vendors, equipment, policies and general administrative overhead. Purpose-built hardware is often used for smaller sites that might need only one service – typically SD WAN or Software Defined Secure Branch (SDSB) -- for the foreseeable future (e.g. a retail outlet or a remote office). Whatever the situation, there are times that using a purpose built device is the best option in terms of cost and efficiency. These purpose built devices are designed to seamlessly work with the same backend orchestration and automation systems in the SDN portfolio. Often, remote sites need more flexibility to change services as requirements or technology evolve. In this case, a simple x86 "white box" universal CPE (uCPE) can be dispatched. The desired application mix will then be deployed over the network once a basic secure network connection has been established to the device. A range of uCPE configurations are available to address different performance, high availability, survivability, and size requirements. As with the software technologies, extensive pre-production testing is performed in Verizon labs with each appliance model series and each service chain to ensure proper performance in the field. This eliminates the need to expend time and effort on extensive re-testing the solutions for your digital transformation. Removing the permutations of service-chained configurations and confirming the versions of code for each partner as fully operational has proven to be a challenge for most implementations in our industry. Verizon has conquered this hurdle with an extensive blue-print and design review process to ensure success for your environment. For the many companies that have migrated their applications to the public cloud, VNS offers a hosted solution that allows cloud-based applications to be connected via co-located hosted nodes, increasing the application performance characteristics. For example, if you want SD WAN routing functionality at each site, but want an advanced firewall to serve multiple sites with the same policy requirements, then it might make sense to centralize the security services rather than having costly security nodes installed at each remote location. Some VNS services are available on public cloud platforms, such as Amazon Web Services (AWS). Realizing enterprises have assets across many different technology service providers, Verizon made its VNS SD WAN network function available directly from the AWS public cloud. With VNS, you benefit from an advanced self-service portal that provides a detailed view of security postures, regional and branch level policies, and your micro-services inventory. Think of it as a "shared management" model; you have the ability to manage your sensitive policy changes in near real time, while we manage the automation and complexity behind the scenes. This service offers simplified, centralized, near real-time control of important parameters (security policies, access controls, cost, and performance). Through the portal, you will also have extensive end-to- end visibility of exactly how your sites, applications and network services are performing holistically. This can help you quickly pinpoint and resolve issues, typically without the need to engage expensive senior-level network or application engineering resources. Administration can be further simplified with a centralized contracting and billing option that will offer a single bill for multiple locations across the globe. The utility-based contracting and billing model means that there is no longer a need to hold separate contracts with multiple vendors, just a single master contract with Verizon. This offers flexibility to change vendors and functionality as your business needs dictate (e.g. as might be the case with seasonal or cyclical demand spikes). You can also change the features within the services you choose from different vendors. This micro-services approach makes it possible for you to tailor what you need to meet market demands and your business policy requirements on a business segment or down to a site basis. Figure 4: Self-service portal for more transparent service monitoring,Closely coupled to orchestration, deep integration with Verizon's Network Management and Network Analytics platforms and closed-loop service assurance mechanism helps monitor and heal virtual network services in near real time. Decisions are made based on parameters and service policies defined by us or you. For example, the following set of actions might happen:,You can think of it almost like spinning-up a new virtual machine to replace one that has stopped, in near-real time. Benefits of closed loop assurance can include improved cost control and simplified and less time-consuming troubleshooting. Administration can be further simplified with a centralized contracting and billing option that will offer a single bill for multiple locations across the globe.

Now is the time to act. Your successful digital transformation is our priority. Your Verizon account manager is prepared to show you the way. Are you ready to take the next step in your digital transformation journey?,As an enterprise leader, it helps to have a basic understanding of what goes into the fundamental concepts of "Software Defined Networking" (SDN) and how it is used to achieve digital network transformation. SDN changes the network design paradigm by introducing network programmability and abstraction integral with the architecture itself. SDN is about separating the network control and data planes in L1-4 devices (Figure 6). This enables independent scaling of control plane resources and data plane resources, maximizing utilization of hardware resources. In addition, control plane centralization reduces the number of managed control plane instances, thus simplifying operations and enabling orchestration automation. The idea of centralized network control can be generalized, resulting in a broader definition of SDN: standard protocols and data models that enable logically centralized control across multi-vendor and multi-layer networks. SDN Controllers expose abstracted topology and service data models towards northbound (WAN) systems, simplifying orchestration of end-to-end services and enabling the introduction of innovative applications that rely on network programmability. Therefore, network applications perform more as software as opposed to physical assets. Figure 6: Fundamental SDN concept, the separation of control and data planes,The second important concept in understanding SDN is network function virtualization (NFV). This is based on the use of commercial off-the-shelf (COTS) hardware for general purpose compute, storage, and network. Software versions of network functions necessary for running the network are decoupled from the underlying hardware (NFV infrastructure). NFV enables deployment of virtual network functions (VNF's) and end points within a single operator network or between different operator networks. VNF's can be deployed in networks that already have corresponding physical network functions (PNFs) or in networks that do not have corresponding PNFs. It is important to note, however, that simple investment in COTS appliances does not negate the need for preproduction deployment testing to ensure that each network function technology performs according to expectations and requirements. This is especially true when service chaining disparate technologies and distinctly separate IT functions in a single vCPE or hosted platform. Whether deploying small and large scale SDN networks, this need for testing and integration by the operator cannot be over-emphasized; it is crucial for a successful transformation. It is something that is extremely difficult for the enterprise, with its limited resources and divergent business objectives, to achieve. The high-level architecture of fully realized cloud or container based systems shown in Figures 2 and 3 will not immediately replace existing systems and procedures. Rather, the existing systems will be integrated into the new framework, then phased out and replaced by newer systems. For example, WAN SDN Control can be introduced in specific network domains or for specific services, such as Data Center Interconnect. Similarly, EEO can be introduced to orchestrate specific services that rely heavily on virtualized functions, such as SGi-LAN services, while existing services continue to be managed through existing OSS, BSS and EMS systems. Operational disruption in any organization can cause devastating, even catastrophic, effects on business operations. Considering that the potential risk of disruption is one of the main barriers to digital transformation, it's important to mitigate this risk through an integrated underlying architecture. Verizon's approach of using well-tested Open Source systems, such as OpenStack ONAP and MANO, designed to unify the management of both physical and virtual network functions across the global network, can minimize disruption at every stage of service deployment and the ongoing lifecycle of an enterprise's digital network transformation. Figure 7: High-Level Management and Control Architecture,The desire for service automation is not new, but in the past it was difficult to achieve. Due to a lack of standard interfaces and data models, OSS systems required detailed knowledge of the vendor and technology domains with which they had to integrate. By building on increased abstraction and emerging standards, Verizon embarked on this journey to enable automation tools built over the existing reactive managed technologies, with the intention to replace legacy components as needed over time. Figure 8: Abstraction, automation and standardization enable service orchestration,Traditional network provisioning is a multi-step, labor intensive process for CPE deployments. The design phase, sourcing, and on site provisioning can typically take several weeks, delaying growth and return on investment. Manual provisioning performed by skilled technical staff is time consuming and vulnerable to human error. Since low-touch provisioning has less human intervention, there is less chance of manual errors and increased reliability. Low-touch provisioning is an automated service delivery model which reduces the need for high-value technical personnel to be dispatched to remote site locations to install new services. Instead, once the universal CPE (uCPE) is delivered to the location and powered-up, a secure connection will be made to back-end orchestration servers at initial power up and registration activated on the network. Configurations that have been ordered will automatically be received. Verizon has the ability to deliver services through low-touch provisioning over broadband, internet dedicated circuits, and MPLS as well as Wireless 4G LTE. In the case of a Hosted Network Services model, provisioning can be done quickly --- in some cases within a matter of days after the time the order is sent to service delivery. Organizations are moving away from traditional OSS stacks to a simplified, pre-integrated horizontal architecture that can be readily configured to support specific service offerings including those that leverage Virtual Network Functions (VNF) such as SD WAN, mobile Virtual Private Networks (VPN), and 5G network slicing. The right orchestration platform brings together a comprehensive and flexible end-to-end solution to manage the rapid deployments needed to manage, monitor, and maintain the needs of your applications-based services in hybrid environments. Verizon's VNS solution is driven by the Verizon Network Service provisioning and orchestration platform which allows us to automate complex service provisioning, delivery, and assurance. Verizon Network Service provisioning enables:,• Rigorous design and validation of template Blueprints, prior to release,• Standardized Network Service templates (referred to as Blueprints in Verizon) that are the hallmark of service provisioning automation,• Catalog and inventory-driven service order management,• Central repository for inventory management with all service configurations,• NFV Orchestration with VNF and network service resource orchestration and networking based on Open Source OVF, HEAT, and Tosca models and to eventually incorporating container-based deployments. • Service configuration management with model-driven provisioning based on Open Source YANG and REST models and agnostic of the protocol leveraged by the VNFs for the configuration interface,• VNF Management with VNF and virtual network service modeling and lifecycle management,• Dynamic network topology discovery and automated VNF snapshot management ensuring continuous monitoring and quick recovery in the event of service faults,• Closed-loop policy-based service assurance supporting customer Service Level Agreements (SLA) using policies based on potential VM fault alarmsVerizon's Enterprise Orchestration platform fully automates multiple layers of complex processes across the service lifecycle allowing rapid onboarding and validation of VNFs and service chains to create new solutions, including automated resource management, service design and configuration, and policy-based service assurance. Significant investment has been made to integrate Verizon's state of the industry Multi-vendor Event Translation Layer (METAL) system to communicate with our Integrated Management Platform for Advanced Communications (IMPACT) and SMARTs service assurance platforms. The Enterprise Orchestration system interfaces with IMPACT to provide durable alarms and notifications for service impacting events. This is used to facilitate effective and efficient event management and customer notifications. Verizon uses dynamic topology discovery of the VNF's and Network Services to ensure the monitoring is based on the true topology of the network. Closed Loop Assurance uses the alarms generated by VNF's and reported to the monitoring systems to perform appropriate corrective actions. For example, if a VNF goes down due to a software failure, the event will be immediately identified by the monitoring tools which will determine how to best re-start the VNF (providing resiliency to the given VNF).
