支持流量工程的GMPLS-Based OBS网络研究

Study on GMPLS-based OBS networks supporting traffic engineering

为了解决光突发交换中网络拥塞等问题,提出一种基于链路状态广播消息拓展的改进流量工程实现机制,分析了LSP(标签交换路径)的建立机制和BDP(突发数据包)的传输过程。仿真结果表明,该机制能有效地降低网络的丢包率,实现流量的合理分配。

For eliminating congestion in Optical Burst Switching （OBS） networks, an improved Traffic Engineering （TE） mechanism based on the extension of the link state broadcast messages is proposed and the setup mechanism of LSP and the transmission process of BDP are analyzed. Simulation results demonstrate that this mechanism effectively reduces the network packet loss rate and realizes the rational distribution of the traffic.
