摘要: 为适应实时的网络流量需求,并及时发现网络故障,基于经典的在线分布式流量工程协议TeXCP,提出多路流量工程协议(MTE)。该协议包括链路代价收集和链路发送概率调整2个模块,分别对应于TeXCP中的路径探测和负载均衡模块,使用非可加和的路径最大链路利用率作为路径代价,修改并简化TeXCP的稳定性机制。理论和仿真实验结果证明,MTE能够收敛到网络流量的均衡状态,稳定性更好。

Abstract: In order to adapt to the real-time network traffic demand,and find the network fault in time,based on classic online distributed traffic engineering protocol TeXCP,this paper proposes Multi-path Traffic Engineering(MTE) protocol.The protocol consists of the link cost collection module and link transmission probability adjustment module,which corresponds path detection module and load balance module of TeXCP respectively.It adopts the non-additive path maximum utilization rate as the path cost.The stability mechanism of TeXCP is modified and simplified.The results of theory and simulation prove that MTE can converge to the equilibrium state of network traffic,and the stability is better.

Key words: traffic engineering, multi-path routing, non-additive path cost, network stability mechanism, equilibria
