By improving the existing protocols of the ip network , the ietf developed the gmpls protocol , which can be used in various networks including the astn . this protocol pays particular attention to routing and signaling protocols and adopts the peer model Ietf通过对ip网原有协议的改进，提出了可应用于包括astn在内的多种网络的通用多协议标签交换（ gmpls ）协议，主要侧重于路由和信令协议，采用对等模型。
The mpls technology was raised just in order to make the most of the switching technology in the core of the network and the ip routing technology on the edge of the network . before presenting the solution of the mpls , there are many integration model , the basic method adopted by them were all carry the control information from the ip router , and combine it with the transmition capability and the label switching of the atm switching machine , accordingly constructing a high speed and economic multi layer switching router . but , all these solutions can not communicate and just suit for adapting the atm as the second layer transmiting link , can n ' t work on other interface ( fr , ppp , and ethernet ) , this is obviously conflict with the developing way of the based on packet of the internet 多协议标签交换( mpls )技术就是为了综合利用网络核心的交换技术和网络边缘的ip路由技术各自的优点而产生的。在mpls技术方案提出之前已有的各种集成模型解决方案所采取的基本方法都是从ip路由器获取控制信息，将其与atm交换机的转发性能和标签交换方式相结合，从而构建成一个高速而经济的多层交换路由器。但是，各种方案彼此不能互通，而且仅适用于以atm作为第2层的传输链路，不能工作在其他多种媒体(如帧中继、点对点协议、以太网)中，这与internet基于分组的发展方向相矛盾。
Mpls ( multi - protocol label switching ) opposed to be the backbone network technology of next generation internet . it takes good use of the switching technology of the core of network and the ip routing technology of the edge of network , and with the reasonable control of network traffic mpls can help to optimizing the utilization of network resource and improving the performance of network 多协议标签交换技术mpls ( multi ? protocollabelswitching )是下一代internet宽带网络技术,它综合利用网络核心的交换技术和网络边缘的ip路由技术,对网络流量进行合理的控制,使得网络流量均衡地分布在网络中,从而提高网络性能,具备流量工程的功能。
As two diffent network technology , mpls can resolve many problems that ip network is face with now . and multicast can relax the press that more bandwidth is needed before the network framework is not changed in some application scope , which is just the application that result to consume more bandwidth such as net meeting , net game , multimedia remote education and so on 与ip相关联的多协议标签交换( mpls )技术,可以解决包括qos在内的许多目前ip网络无法克服的问题,而组播能够在不改变当前网络结构的前提下在一定应用范围内有效的缓解带宽消耗过大的压力,而这些应用范围恰好是可能导致带宽消耗过大的应用,如网络视频会议、网络音频/视频广播、多媒体远程教育、网络游戏等等。
( email , web surf , broad band , multimedia , qos etc ) in 90 ' s , atm proved super excellent solution for performance and raffle engineering to isp . and many carriers found it is very economical to implement internet multi - service in atm network . but ip - based network is becoming more prevalent each year , pure atm based network is impossible in reality . in fact , today " s atm network is used to carry ip based traffic . so people wish to combine ip traffic and atm function in one network technology Mpls ( multiprotocollabelswitch ，多协议标签交换)就是在这种背景下产生的一种技术，而且越来越被运营商看好，成为在ip网络运营商提供增值业务的手段。 mpls是“多协议标记交换” ( multiprotocollabelswitching )的缩写。它是一种根据“带路由信息”的标记进行分组交换的新型网络通信技术，结合了交换技术和路由技术的诸多特点。
High - speed , muti - services and economy have become the major issues of the future ip backbone technology as far as thes poiflt is concerned , thes paper explores layer 3 switdrig technology which separates control component and forward compontal in the traditional roulers . two forwarding al gori thms - - - - d ata - driven mo d el and top olo gy driven model are also compared , a next generation ip backbone echno l o gy - - - - multiproto co l label switching is developed , with its operation and its deployinent in traffic engineering , c1ass - ofservce and virtual private network 本文从未来ip骨干网技术所要求的高速化、多业务支持、经济性出发，介绍了在传统路由器基础上将控制部件和转发部件分离的第三层交换技术，比较了数据驱动模型和控制驱动(拓扑驱动)模型两种转发算法，并由此引出下一代ip骨干网络技术? ?多协议标记交换，阐述了其工作原理以及在流量工程、服务等级区分和虚拟专用网中的应用。
