SDN is the first architecture to completely change the network through network control and programmable. Network control is used for open software systems, not dedicated hardware and software. NFV allows virtualization to run on x86-based open platform hardware. Successful deployments such as DPI, firewall, SD-WAN, and vCPE. From architecture to wireless access, NFV can improve 5G in a variety of ways. The following is the 5G cloud RAN architecture. Where will virtualization work? Virtualization may take over most of the edge elements of a 5G network, especially access, Radio Access Network (RAN), and User Equipment (UE). SDN technology will also be implemented on the access, edge and core networks. How will SDN run on 5G core network and access network? The 5G core network and access network may use network slicing technology to split a physical infrastructure into multiple virtual networks so that each slice provides a different and unique connection under the same infrastructure. For example, a network slice can provide high throughput and ultra-low latency for applications such as autonomous vehicles or VR/AR. To achieve this flexibility, each slice must be able to access different types of resources, whether physical or virtual (VNF). The core network will also control the vCPE (virtual client device) and push the VNF to the customer's general purpose hardware. It will also provide management and connectivity for edge-located SD-WAN devices. How will 5G be virtualized at the edge? Edge virtualization will be one of the most important components of 5G. At the edge, 5G needs to be able to handle different services and devices. Read More; https://www.fieldengineer.com/sd-wan/why-is-sd-wan-adoption |
