摘要
提出了一种分布式动态调节的负载均衡机制,采用Hash表的负载均衡策略,具有保证流顺序、按链路带宽比例分配流量以及基于流量历史记录的实时动态调整的特点。模拟实验评价了Hash表调整、调整时间间隔、判定阈值对算法性能的影响。
A distributed and dynamic load balancing mechanism was proposed. To preserve per-flow packet ordering and support unequal weighted distribution, hashing-based algorithm with dynamic adapting according to history records on traffic was used. Simulation experiments evaluate the effects of hash-tuning with varied time window and threshold.
