摘要该文在对MPLS工作原理深入了解的基础上，提出了一种新的路由模型S-DQRA，希望在为业务建立LSP之初不仅考虑业务的实际需求，而且保证网络资源的合理利用。在此基础上，为了保证可靠的服务，又提出了一种新的重路由模型S-DQRRA。在失效发生时迅速启动，将工作路径上的流量切换到备份路径上。最后，用NS对这两种模型进行了仿真实验，并分别与其经典的模型进行了比较，实验结果表明该文提出的路由及重路由模型均具备良好的工作性能。

Abstract：In this paper, based on studying the routing algorithm and re-router model of MPLS Traffic Engineering，a new routing model S-DQRA is proposed. It not only considers the practical requirements of the traffic when the LSP is initially established, but also guarantees reasonable resource utilization. Moreover, for the warrant of more reliable service, a novel re-router model S-DQRRA is proposed based on the S-DQRA model. It works when any invalidation occurs, and switches the traffic from the work path to the backup path. Finally, extensive simulation using NS-2 is conducted to verify the effectiveness of these two models. Compared with the classical models, the experimental results indicate that the models have the favorable working performance.
