自适应RED算法在OBS网络中的应用

Application of adaptive random early detection algorithm adopted in optical burst switching network

队列管理是光突发交换(OBS)网络边缘节点的重要功能之一。对随机早期检测(RED)队列管理算法及两种自适应RED算法在OBS网络中的应用进行了研究和仿真分析。仿真结果表示:动态调整队列权重的自适应RED算法和动态调整最大丢包率的自适应RED算法均能改进RED算法的性能,但是后者的性能优于前者。

Queue management is one of the key functions in the edge nodes of optical burst switching （OBS） network. In this paper, the random early detection （RED） algorithm and two variations of RED （adaptive RED） are studied and simulated in the scenario of OBS network. Simulation results show that both the queue-weight-adjusted adaptive RED and the maximum packet dropping probability-adjusted adaptive RED can improve the performance of RED and the latter outperforms the former.
