基于链路聚合控制协议的堆叠网络设计与应用

摘要

文章介绍了国内最大卧式空间环境模拟器KM7A的系统网络架构，在该网络中应用了堆叠网络以及链路聚合控制协议（LACP），通过链路聚合控制协议对所有关键设备进行链路绑定，实现了关键设备和数据链路的冗余，大大缩短了主/备试验网络数据链路的切换时间，避免了单链路失效，提升了数据传输链路的稳定性和故障容错性。%This paper presents the network architecture of KM7A, which is the largest horizontal space environment simulator in China. The stacking network and the LACP (link aggregation control protocol) are applied in this network. All pivotal equipment are channel bonded via the LACP to realize the redundancy of the key equipment and the data channel, to reduce the switching time of the data channel for the active-standby test network, to avoid the single-link failure, and to advance the stability and fault tolerance of the data transmission link.
