SR技术在二层虚拟专网中基于MPLS的实现与性能分析

Implementation and Performance Analysis of SR Technology in Layer 2 Virtual Private Networks Based on MPLS

文章聚焦于分段路由(Segment Routing,SR)技术在多协议标签交换(Multiprotocol Label Switching,MPLS)中的应用,尤其关注其在二层虚拟专网(Layer 2 Virtual Private Network,L2VPN)中的实现和性能。SR通过标签堆栈实现路径动态引导。控制平面协同工作进行路径计算、标签分配和拓扑管理,数据平面执行实际数据包传输。然后进行性能测试,将测试结果与传统方法进行对比对比,结果表明SR在二层虚拟专网中性能优于传统的传输方式。

In this study,the application of Segment Routing(SR)technology in Multiprotocol Label Switching(MPLS)is focused on,with particular attention to its implementation and performance in the Layer 2 Virtual Private Network(L2VPN).SR achieves dynamic path guidance through label stack.Control plane collaborative work for path calculation,label allocation,and topology management,while the data plane performs actual packet transmission.Then,performance testing was conducted,and the test results were compared with traditional methods.The results showed that SR performs better than traditional transmission methods in Layer 2 Virtual Private Network.
