摘要
随着5G建设周期来临,电信云网络进入大规模部署阶段,VxLAN和SDN成为解决多租户和多DC组网的必备技术。目前业界提供以物理交换机EVPN为核心的硬件VTEP方案以及以虚拟化技术为核心的软件VTEP方案。以VLAN平滑演进到VxLAN为切入点,比较了2种方案的优劣,提出了平滑改造方法,并阐述了相关过程。
With the advent of 5G construction cycle,telecom cloud network has entered the stage of large-scale deployment. VxLAN and SDN become the necessary technologies to solve multi-tenant and multi-DC networking. There are currently two solutions in the industry:hardware VTEP centralized by physical switch and software VTEP based on virtualized technique. Taking the smooth evolution of VLAN to VxLAN as the starting point,it compares the advantages and disadvantages of the two schemes,puts forward the smooth transformation method,and expounds the relevant process.
