主动式队列管理(Active Queue Management
AQM)技术是IETF为了解决Internet拥塞控制问题而提出的一种路由器缓存管理技术.本文对几种主要AQM算法RED、BLUE、ARED和SRED的性能在基于ns-2仿真实验的基础上进行了比较研究.研究的性能包括队列长度、丢包概率、丢包率、连接数对吞吐量的影响及缓冲区大小对链路利用率的影响等.仿真结果表明BLUE、ARED和SRED在这几方面的性能都要优于RED算法.
To address the problem of TCP end-to-end congestion control
IETF advocates deploying active queue management (AQM) mechanisms in the TCP/IP networks.Several popular AQM algorithms
such as RED (Random Early Detection)
BLUE
ARED (Adaptive RED) and SRED (Stabilized RED)
are compared based on simulations and the performance metrics used in the study are queue size
packet drop probability
packet loss rate
throughput on different connections and link utilization on different buffer size.The simulation results indicate that in all these aspects
the performance of BLUE
ARED and SRED are better than that of RED.Furthermore
ARED and SRED can stabilize queue size and control packet loss rate effectively thus they maintain high link utilization
bounded delays and more certain buffer provision.
