摘要:

提出了一种能够主动测量 SDN 中任何两点间的端到端路径性能的机制,设计了 OpenFlow 测量协议OFMP,实现了无需改变交换机转发规则就能测量两点间特定流的多种性能参数的原型系统 OFMd。实验结果表明,OFMd只需发送一个测试报文就能快速高效地获取多种端到端路径性能参数。

Abstract:

An active SDN measurement mechanism was proposed,which could measure the end-to-end path performance between any two nodes,then the OpenFlow measurement protocol OFMP was designed,and a prototype OFMd was implemented,which could measure multiple performance metrics of the flow between two nodes without changing the switch forwarding rule.The experiment results show that OFMd can acquire multiple end to end path performance metrics only by sending a single probe packet.

Key words: software defined networking, active measurement mechanism, measurement protocol
