摘　　要：流量工程是MPLS技术最重要的应用之一。为实现MPLS流量工程,IETF工作组提出了支持QoS路由机制的OSPF扩展(RFC2676)。在ns下对RFC2676中建议的两种QoS路由算法进行了实现。通过对ns仿真结果的比较,显示了这两种新算法相对于传统SPF算法的优越性,同时也指出了两种算法的不足。Traffic engineering is one of the most important applications of MPLS technology. IETF work group proposed QoS routing mechanisms and OSPF extensions （RFC2676） to support MPLS traffic engineering. The two routing algorithms recommended by RFC2676 were implemented in ns （network simulator）. Simulation results were compared to show the advantages of the two new algorithms over traditional SPF algorithm. Disadvantages of the two algorithms were also pointed out.
