| 摘要: |
| 传统的IP路由协议采用最短路径算法(SPF),极易造成网络的拥塞.流量工程是目前网络中实现负载均衡和提高网络性能的一个重要技术.文中简要介绍了MPLS流量工程,重点分析了MPLS流量工程中所使用的路由协议约束路由,给出了约束的计算方法以及路由度量选择的准则. |

| Abstract: |
| The use of Shortest Path First(SPF)algorithm in traditional IP routing protocol can cause network congestion.At present,traffic engineering is an important technology to achieve network load balance and enhance network performance.The MPLS traffic engineering is introduced in this paper,and the routing protocol used in MPLS traffic engineering-constrained routing is described.The computation algorithm of constrained routing and principles of choosing routing metrics are given. |
| Key words: MPLS traffic engineering QoS routing constrained routing |
