摘要

本文基于IP网络提出了一种分组丢弃控制方案——动态部分缓冲共享.和已有的静态部分缓冲共享方案相比

新方案根据分组丢弃行为对控制阈值进行动态调整

从而对网络流量的变化具有更优的适应性.同时新方案也避免了复杂的阈值设置问题

任意设定的初始阈值都不会影响系统稳态性能.实验结果显示

新方案可以保证稳定的相对丢失率性能

并且在相同的流量条件下比原有方案具有更低的抖动延迟.

Abstract

We present a packet loss control scheme for IP networks-Dynamic Partial Buffer Sharing (DPBS).Compared with Static Partial Buffer Sharing (SPBS)

the new scheme adjusts control thresholds dynamically according to packets loss behavior

which is endowed with better adaptability to changing network traffic.Also

DPBS avoids complicated threshold-setting problem:arbitrary initial value will never degrade system steady-state performance.Simulation results show that

DPBS can assure nearly fixed relative loss ratio

and its loss jitter performance is also better than SPBS under same traffic condition.
