Digital Network Transformation White Paper Sol.utions
Critical success factors for Digital Network Transformations. Beth Cohen SD WAN Product Strategist Verizon Business GroupThe white paper is designed for: Determine the level of effort, availability, and best path for undertaking a legacy infrastructure technology refresh and migration to SDN technologies in order to minimize surprises and determine level of effort and organizational technology readiness. Manage the deployment by starting with Proof of Concept (POC) lab testing, followed by a field test program or small-scale deployment before undertaking a major deployment. A test or small-scale deployment will allow risks to be identified and mitigated while validating business benefits, operational improvements, and potential cost savings. Have plans in motion targeted at addressing customer demand, improving customer experience, and/or getting products and services to market faster with the understanding that the network is an integral part and enabler of the transformation project. 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. 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.

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).

Learn moreWhat is Private IP? Guide to Understand Private IP
We've got some great deals going on right now exclusively for our online customers... chat now to hear more! What is private IP?,Be informed when securing your corner of the cloud. For businesses large and small, walls are coming down and physical boundaries are disappearing wherever markets are growing. More companies are going mobile as they expand their remote workforces to offer a more responsive customer experience. Others are taking advantage of new connectivity options to quickly, securely and affordably establish a presence closer to customers and new opportunities across the U.S. These companies have outgrown standard ways of getting online. They can no longer work with a single shared connection to the internet. At the same time, they're not ready for an enterprise-grade suite of private connections more typical of a multi-million-dollar organization with thousands of employees and a sky-high annual IT budget. They need a secure space in the cloud dedicated to their operations and data, one that suits their size, budget and specific bandwidth requirements. They also can't afford to invest in a whole new networking approach that may need considerable reconfiguring a year or two down the road. Many companies in this camp simply need to connect and collaborate via, for example, conference calling and messaging. They need a safe and efficient means for storing, sending and receiving large files across widely distributed locations. They need an online seat that is the right fit for current business conditions, and that can scale up or down, bandwidth-wise, as their operational situation changes. Private IP addressing often fits the bill for growing companies with limited IT resources. Private IP, or PIP, provides a simple, dedicated cloud-based network that allows businesses to consolidate applications into a single network infrastructure. It allows for relatively uncomplicated connectivity very similar to that of the public internet while enabling the flexibility, security and reliability of a gated network like a VPN. Whether your company is on the brink of major growth or struggling against the limitations of insufficient bandwidth for your current volume of business, consider whether private IP may be right for you. Take a look at a few frequently—asked questions before making your next networking move. What types of challenges are addressed by private IP?,Small- to medium-sized businesses often benefit from PIP addressing. Here's a scenario. A hiring firm—let's call it Brains Co.—has eight employees in a Chicago office. Brains is expanding operations and headcount into Seattle and Atlanta. The company has plans for two more offices in the next 20 months to accommodate clients in New York and Dallas. The five-year-old company has grown from two clients in the legal sector to more than 150 across the country in industries ranging from healthcare to IT and government affairs. Headcount will increase, and many of the new hires will work remotely and travel often. This company must regularly transfer large files in a wide range of formats. It also must conduct webinars and convene teleconferences across time zones on very short notice. It has compliance requirements to meet, and data must be kept carefully secured at all times. It regularly uses video for multi-site training and will need advanced collaboration and presence tools for its highly-mobile employees. Brains also doesn't have the resources to reconfigure an inappropriately architected network as it rolls out new services. For Brains Co. private IP can:,How does private IP return value?,Depending on how your PIP is structured, and what your service provider offers, ROI advantages can amount to an IT team at your fingertips. Your online-connections experience could be completely transformed. Private IP can:,So, what's under the hood? How does private IP work?,This is where things can get technical. Not hard, if you're an IT specialist, but arcane to many others. However, a cursory look at protocols and addressing may help clarify how the relatively simple PIP technology allows users to effectively communicate over a secure, efficient and flexible private-network infrastructure. It serves as a foundation for automating and streamlining business processes such as e-commerce, shared intranets and extranets. PIP provides connections into a private external network, or extranet, that move data and establish off-site, remote links. It does so in ways that are very similar to the public internet everybody uses to check social media, stream videos, download apps and more. The public and private IP versions use very similar protocols for routing. The public internet uses border gateway protocol (BGP) which is also used by most multiprotocol label switching (MPLS) networks on which PIP is based. This routing helps the user experience because working in PIP mode seems no different from using the public internet. It is widely tapped for communications between autonomous networks and has extensive routing policies for implementations of complex or simple networks. MPLS technology used by private IP allows for the integration of Layer 2 and Layer 3 routing. The layers are among the seven that comprise the OSI (Open Systems Interconnection) model of networking common in telecommunications for, among other things, cellular service. This network-service platform provides a base that is scalable, survivable and efficient without sacrificing performance. The private IP network is a closed and private MPLS backbone (meaning that it allows no internet connectivity). It doesn't support any direct customer-access connections. MPLS networks will automatically detect and dynamically re-route around transmission-path failures. With private networks, a distinct set of addresses has been established by the authorizing organization (Internet Assigned Numbers Authority) to locate computers on a specific PIP. For the public internet, the authorizing organization (Internet Corporation for Assigned Names and Numbers) has designated a different set of addresses for devices that access that public network, or internet. This way, the routing of signals to and from specific private IP networks is kept separate from the public internet, and from other PIP networks. These addresses, whether public or private, are like mailing addresses for homes and businesses. Every computing device that accesses a PIP or the public internet must have a distinct address in the appropriate range for connections to go through. It's like the incorrect or non-existent mailing address resulting in an undeliverable letter. Or paycheck. The private IP addressing architecture uses IPv4 and IPv6 specifications to define the private addressing ranges. IP packets that use addresses in these ranges cannot be routed through the public internet. Public IP addresses can be found through an internet lookup. Simply type "what is my IP address" into your browser address bar, and hit enter. Private IP addresses cannot be found this way. If you're curious about PIP addressing, how routers are NAT (network address translation) devices, and how machines and users routinely bounce to and from public and private networks everyday, all the time, there are infinite resources on the subject. Just search on "IP addresses: Everything you need to know," or something similar. What are the advantages and disadvantages of private IP?,The internet is teeming with cyber-pestilences and villains of every stripe. That's why data protection and privacy top the list of advantages for those who choose private IP. Devices aren't exposed to the public internet, so hackers have a harder time getting at them and their users. Private IP networks are isolated from other networks, making them less vulnerable to such common issues as external equipment malfunctions or connectivity loss. If a problem does occur, pinpointing its cause and solution is a simpler matter that can save precious time and budget dollars. Private IP networks involve additional setup and non-standard configurations. They also will not interact with the public internet; alternative solutions are needed. These are usually supplied by most service providers for users who want seamless access to both private and public (e.g. internet) networks. With PIP, the cost of server space and equipment, as well as for configuration and maintenance, is not spread across millions of users as it is with the public internet. Instead, the operator providing the private IP carries these costs, of which a portion is passed on to users. Is private IP right for you?,Now that you know more about what's involved with private IP, you should be better equipped to make informed decisions as your business grows. The technology is a popular choice for governments, enterprises, start-ups and businesses in the middle of the market. It can be an ideal solution for you, too, as you boost your network for that next big opportunity.
