不同数据包大小对RED性能的影响

Effect of different packet sizes on RED performance

Stefaan De Cnodder, Omar Elloumi, Kenny Pauwels

摘要:

我们认为随机早期检测(RED)的适应作为一个积极的队列管理算法,TCP流量在互联网网关中使用不同的最大传输单元(MTU)。我们研究了现有的两种RED变体,并指出了两者的弱点。第一种变体,其中丢弃概率与数据包大小无关,区分具有较小MTU的连接。对于具有较高MTU的连接,第二种变体导致非常高的分组丢失率(PLR),并且因此导致低有效吞吐量。我们表明,在损失和有效吞吐量方面的公平性,可以提供通过适当的设置的RED算法。

英文摘要:

We consider the adaptation of random early detection (RED) as an active queue management algorithm for TCP traffic in Internet gateways where different maximum transfer units (MTUs) are used. We studied the two existing RED variants and point out a weakness in both. The first variant where the drop probability is independent from the packet size discriminates connections with smaller MTUs. The second variant results in a very high Packet Loss Ratio (PLR), and as a consequence low goodput, for connections with higher MTUs. We show that fairness in terms of loss and goodput can be supplied through an appropriate setting of the RED algorithm.
