摘要: 针对真实网络trace较大流数目少但其所占流量比重却很大的现象,提出只调整较大流的分流算法HAMF。模拟实验以真实网络trace为输入,验证表明该算法位流均衡性较好、流破坏率低、丢包率极低,符合安全处理要求。与SHI算法相比,各方面性能均有提高,但算法在可容忍的范围内复杂性有所增加。

关键词: 网络安全, 较大流, 流破坏率

Abstract: By investigating characteristics of Internet traffic, this paper discoveres that moderate flows are few but have large proportion of the total bytes. It proposes a novel load balance algorithm named HAMF, which only adjusts the moderate flows when unbalanced. Validated by simulation, the scheme dispatches the bytes of load in a balanced way, disrupts flows at low rate, discards packets at very low rate, and satisfies the demand of network security. Compared with SHI scheme, the algorithm has better performances, but it is a little more complex.

Key words: network security, moderate flow, flow-disruption rate
