基于可编程路由技术的MPLS单标签分流传输算法

Flow-splitting algorithm of MPLS single label based on programmable router

为提高数据传输的QoS(服务质量),运用MPLS(多协议标签交换)、并发多路径和可编程路由技术,提出了multipathMPLS算法,实现了单个转发等价类标签进行多个标签交换路径并行分流的传输算法。NS2仿真实验证明,该算法具备MPLS高速转发、并发多路径较高吞吐量、可编程路由器灵活部署等优点。

To increase the QoS （quality of service） of data transmission, a novel flow-splitting algorithm, multipathMPLS, was proposed, which combined three technologies of MPLS （multi protocol label switching）, concurrent multi-path and programmable router. MultipathMPLS implementes the flow-splitting transmission for the same FEC （forwarding equivalence class）. Via the network simulation tool （NS2）, this algorithm can obtain the high forwarding performance of MPLS, high throughput of concurrent multi-path and flexible configuration of programmable router.
