Eth-Trunk负载分担在通信类设备上的应用

为了有效分担业务数据流,提出了使用华为交换机Eth-Trunk功能进行负载分担的方法。该方法采用了基于LACP协议的链路聚合模式,选取了合适的LACP Timeout对跨接设备进行故障判断。对单播和组播数据流采用不同的分担策略,并手动调整数据流流入方向上交换机的非聚合口直到分配给聚合组各成员端口的数据流个数相对平均为止。经验证,该方法效果较好,不仅可以解决Eth-Trunk负载分担固有HASH属性带来的分配结果随机的问题,也能保证通过任一跨接设备的数据流个数不超过其处理极限。

Application of Eth-Trunk Load Balancing in Communication Equipment

In order to effectively share the service data flows,a method for load sharing using the Eth-Trunk function of Huawei switches is proposed.This method uses the link aggregation mode based on the LACP protocol,and selects the appropriate LACP Timeout to judge the faults of the crossover device.Different unicast and multicast data streams are processed with different sharing strategies,and the non-aggregated ports of the switch in the direction of data stream inflow are manually adjusted until the data streams assigned to the member ports of the aggregation group are relatively even.Experiment indicates that this method works well,and not only solves the problem of random distribution results caused by the inherent HASH attribute of Eth-Trunk load sharing,but also ensures that the number of data streams passing through any crossover device does not exceed its processing limit.
