一种新的IP分组丢弃策略PRDP

A NEW PRIORITY-BASED IP PACKETS DISCARDING POLICY

该文分析了IP业务在MPLS/DiffServ上运行的特点,从考虑业务量工程性能的角度出发提出了一种新的IP分组优先级的划分方法,并在此基础上给出了一种新的IP分组丢弃算法——基于优先级的丢弃策略(PBDP)。考虑到随机早检测策略(RED)的优点,将PBDP与RED相结合,得到一种改进的算法——基于优先级的RED策略(PRDP),仿真结果表明这种算法在提高全网性能上有优势,其性能优于传统的“尾丢弃”策略。

Concerning about the feature of IP traffic, this paper propose a new Priority-Based Discarding Policy (PBDP) from the view of traffic engineering, and further more gives a advanced RED algorithm PROP (Priority-based RED Discarding Policy), which combining the virtue of RED and PBDP. Considering real-time and non-real-time traffic, simulation shows the PBDP is better than traditional discarding policy, and the PROP is the best of all.
