摘要:
在MPLS网络标签交换路径(LSP)模型中,通常采用第二层直通式(L2-CTS)或第三层缺省路由交换技术。传统的L2-CTS是基于源节点到目的节点传输(P2P)的,没有考虑到建立的LSP是否是最佳。文中提出了一种改进的L2-CTS技术,根据标记交换路由器(LSR)和标记边界路由器(LER)建立的网络拓扑信息,LSR利用Dijkstra算法来计算最短的LSP,从而提高了网络传输效率。理论分析及仿真结果表明,在MPLS网络中,该改进方法可以有效减小网络传输时延,并提高传输流分发到不同标记交换路径的效率,提高了
Abstract:
In the labeled switching path(LSP) model of MPLS network,Layer 2 Cut-Through Switching(L2-CTS) and Layer 3 default routing switching are usually used.The traditional solution for the L2-CTS uses the source and destination addresses to transmit packet without considering whether the LSP is the best.In this paper,proposed an enhanced L2-CTS technique,which uses the Dijkstra algorithm to find the shortest LSP according to the network topology built among LSRs and LERs,so as to improve the network efficiency.Theoretics analysis and simulating results show that the improved model of LSP can minimize the overall network transmission delay and improve the efficiency which distributes the traffic on each different LSPs in the MPLS network,and the quality of service(QoS) of network is also improved
