网络技术M-LAG在数据中心网络中的应用

Application of Network Technology M-LAG in Data Center Network

传统数据中心使用的STP&VRRP的架构,存在链路利用率低、STP网络规模受限、VRRP单活网关等问题。为此,M-LAG应运而生。其是跨设备链路聚合组,是一种实现跨设备链路聚合的机制,大大提高了系统整体可靠性,缩短了业务故障恢复时间。基于此,描述了网络技术M-LAG在数据中心网络中的应用,并与其他数据中心的网络技术进行简单对比分析,以推广网络技术M-LAG。

The traditional STP&VRRP architecture used in data centers has some problems,such as low link utilization,limited STP network size,VRRP single live gateway and so on.Therefore,M-LAG came into being.It is a cross-device link aggregation group,which is a mechanism to achieve cross-device link aggregation.It greatly improves the overall reliability of the system and shortens the service failure recovery time.Based on this,this paper describes the application of network technology M-LAG in data center network,and makes a simple comparison and analysis with other data center network technology in order to promote network technology M-LAG.
