From small and medium-sized enterprises to industry giants, companies have undergone fundamental changes in how to purchase, deploy, manage and develop networks. A new generation of wireless connectivity, software drivers, and cloud delivery networking technologies are emerging to help organizations transform their WANs and provide universal and resilient connectivity to branch offices, mobile networks, and the Internet of Things. Cloud computing , wireless connectivity, the Internet of Things, and big data are the technology foundations for digital transformation, and IT organizations around the world are currently deploying. What these technologies have in common is that they have a profound impact on the corporate wide area network (WAN). Despite significant changes in everything in IT, enterprise WANs have remained relatively static over the past few decades. Enterprises still prefer to use branch networks and wired connections, which are typically IP virtual private networks (VPNs) such as Multiprotocol Label Switching (MPLS), where all traffic passes through a private data center, regardless of its destination. Moreover, the planning and configuration cycle for deploying new sites is still months rather than days. In order for companies to continue to implement digital transformation plans, the WAN must be transformed. WAN transformation Organizations need to connect more “things†in more places, such as branches, vehicles, industrial plants, temporary locations, and remote areas, such as kiosks, surveillance cameras, digital signage, sensors, beacons, and even robots. These have fueled the market demand for universal wireless connectivity. As work becomes more automated, workers need access to business-critical applications and systems anytime, anywhere. All of these people, places, and things connected to the network are transmitting, processing, and storing data in large quantities. As a result, many new support applications and workloads are being deployed in the public cloud, causing private WAN and data center traffic to move to the public Internet and cloud platforms . To meet the needs of today's connected enterprises, WANs must be transformed into more pervasive, agile, and resilient. In other words, there is a need to transform to wireless, software-driven, and cloud delivery. Fortunately, there are several advances in network technology for implementing WAN transitions. They include next-generation 4G and 5G cellular networks, software-defined networking (SDN) and security, as well as cloud-based management and business processes, and even packaging and pricing models. Gigabit LTE and 5G wireless WAN approach As consumers' demand for faster network and video content continues to grow, today's 4G LTE cellular networks are much more common than their wired peer-to-peer networks and are rapidly surpassing without any signs of slowing down. As cellular operators continue to deploy LTE Advanced Pro services in 2018, Gigabit LTE will implement commercial 5G deployments in 2019. 4G LTE has always been the preferred WAN for connecting remote IoT devices and mobile networks, and is the preferred choice for failover of critical branch sites, but it has now become the dominant WAN for highly distributed branch networks. As companies move from multi-protocol label switching (MPLS) to broadband, they can deploy a nationwide high-speed wireless WAN on a per-operator basis instead of dozens or even hundreds of wired Internet service providers (ISPs). ) The services are integrated. Software-defined network for connecting people, places, and things Next-generation WANs require a variety of software-defined architectures to meet all connectivity and security requirements for branch offices, mobile networks, and the Internet of Things. SD-WAN addresses the need for branch and mobile (vehicle) networks and combines multiple wired and/or wireless WAN links (such as MPLS, Internet broadband and 4G LTE) into a hybrid WAN through prescriptive and dynamic policies Control to provide optimal performance and availability for all applications. By leveraging centralized control and management planes, SD-WAN simplifies common management functions, and uses business processes to achieve zero-touch deployment, automatically configure VPN coverage, and develop business-oriented network policies. Software Defined Boundary (SDP) is a cloud-based security service that connects discrete mobile devices and IoT devices on the Internet to data center and cloud computing applications using one or more perimeter-secured private overlay networks. Each overlay has its own private IP address space, which is hidden from the underlying Internet because hackers can't attack things that are not visible. The Software Defined Boundary (SDP) also utilizes a centralized control and management platform to automatically maintain services and provide self-healing and self-optimizing attributes. Cloud management and business processes IT organizations always spend a lot of time deploying new network endpoints and handling network outages, access issues, asset and security monitoring, and application performance issues. This management challenge is exacerbating as more and more data centers, users, vehicles, mobile, and IoT devices connect to the WAN every day. In order to cope with the number, diversity and speed of endpoints brought about by digital transformation, and to achieve without significantly increasing the number of employees, the adoption of cloud-based management and business process network model is essential. The process can be streamlined and automated by applying the data aggregation and business process capabilities inherent in cloud computing infrastructure to network management, configuration, deployment, monitoring, and management. Allows the WAN to scale significantly without the need to increase operations staff. From DIY networks to consumer-as-a-service Achieving WAN transformation is not just limited to deploying a modern software-driven and cloud-delivered infrastructure, but also requires different approaches to purchase, build, manage, and develop infrastructure. The traditional self-service (DIY) model purchases hardware stacks through a wide range of software and support options, and a large number of network engineers with a Ph.D. in TCP/IP centralize and keep these technologies running, nor can they provide the services needed by today's connected enterprise. Agility. Not surprisingly, as WANs tend to be software-driven, like cloud computing, customers can buy and consume just like cloud services . Organizations can adopt a simplified, flexible, and customer-oriented, "service-as-a-service" product model that is expanding in computing from computing and applications to data storage and analytics. Companies need new packaging and pricing models to extend software, hardware and support to customized solutions for branch, mobile and IoT and delivered as cloud services. Start changing now Digital transformation is not a clear goal in the business world. It has brought new opportunities to some companies, increased efficiency and gained market advantage. Traditional enterprise WANs are unable to meet the needs of people who are connected to people, places, and things, as well as new security, management, and procurement models. A new generation of wireless connectivity, software-driven, and cloud-delivered networking technologies have emerged to help transform the enterprise's WAN, provide universal and resilient connectivity to branch offices, mobile networks, and the Internet of Things, and follow cloud computing to be pervasive and full.
