摘要

虚拟化技术的兴起，打破了传统数据中心的架构，数据中心之间存在着大量互联场景，如异地双活、数据中心容灾、数据同步备份、数据迁移、集中式存储、共享虚拟化资源池、虚拟机漂移等，由此产生了大量的东西向流量，需要构建一个可靠、灵活、安全、易于部署的二、三层网络，以满足数据中心互联需求。研究了EVPN VxLAN组网架构，在业内尚无异构多厂商规模商用组网成功案例的情况下，结合中国电信股份有限公司上海分公司LSN数据中心现状，提出并实现了适用于现网的DCI组网。

Abstract

With the rise of virtualization technology

the architecture of traditional data center is disrupted.There exit a large number of interconnected needs among the data centers

such as data center active-active

data center redundancy

data synchronous backup

data migration

integrated data store

shared virtual resource pool

virtual machine drift and so on.Thereby

a large amount of east-west flow was generated

it is necessary to build a reliable

flexible

secure

and easy to deploy layer-2 and layer-3 network to meet the requirement of DCI (data center interconnection).The network architecture of EVPN VxLAN was analyzed

there hasn’t been successful large-scale business case for implementation of multi-vendor DCI EVPN VxLAN networking.Combined with current status of LSN data center of Shanghai Telecom

the deployment of DCI via existing network was proposed and achieved.
