摘　　要：IETF的MPLS工作组,主要目标是开发一个综合选路和交换的标准,把路由选择功能转移到网络边缘,把效率更高、结构更简单的交换功能放在核心网络中。MPLS(多协议标签交换)技术是将第二层交换和第三层路由很好的结合起来的,以十分简洁的方式完成信息传递。路由协议有动态路由协议和静态路由协议之分,动态路由OSPF(Open Shortest Path First)协议允许将连续的网络和主机组合在一起形成一个集合,再加上有接口与这个集合中的任何一个路由相连的路由器形成了一个区域,这样有利于以后的大规模网络的仿真研究。本文中OSPF路由协议为MPLS提供了路由信息。The main objective of IETF＇S MPLS working group is to develop an integrated routing and switching standards, and transfer routing functions to the edge of the network, and put the more efficient, more simple structure switching function on the core network. MPLS （Multi-protocol Label Switching） technology combines switching on the second layer and routing on the third layer well, and finishes messaging in a very simple manner. Routing protocol is divided into the dynamic routing protocol and static routing protocol, OSPF protocol allows combining a continuous network and host together to form a collection. Additional, there is an interface which connects to any one route to form a regional in this collection. This will make the simulation of large-scale network easy. OSPF routing protocol in this article provides the routing information for MPLS.
