| 摘 要： | 链路聚合是一种通过将多条物理链路捆绑成一条逻辑链路来增加带宽的常用技术，但是在基于光纤通道（fibre channel，FC）协议的交换网络中，随着转发流量区域的不断集中，传统静态链路聚合算法存在负载均衡性差、可靠性低的问题。因此提出了一种基于FC协议的动态负载均衡（flow adaptive load balancing， FALB）链路聚合算法，可以实现对流量的动态自适应匹配以及断链可重连保护机制。结果表明，该算法机制相较于静态负载均衡的算法设计，可以将有效带宽比最终收敛到 95%以上，有效提升聚合链路的负载均衡特性和可靠性。

| Abstract: | Link aggregation is a common technology to increase the bandwidth by bundling multiple physical links into a logical link.However, in a switching network based on the fibre channel (FC) protocol, as the forwarding traffic continues to concentrate, traditional static link aggregation algorithms have problems of poor load balance and low reliability.A dynamic load balancing link aggregation algorithm flow adaptive load balancing (FALB) based on FC protocol messages was proposed, which could realize dynamic adaptive matching of traffic and a reconnection protection mechanism for broken links.The results show that compared with the static load balancing algorithm design, the algorithm mechanism could maintain the effective bandwidth ratio above 95%, effectively improving the load balancing characteristics and reliability of the aggregated link. |
