| 中文摘要:SDN是近年来网络界的研究热点之一，自斯坦福大学首次提出SDN概念以来已引起国内外研究人员的极大关注和研究。SDN是一种新的网络体系结构，其核心原则是分离控制平面和数据平面。随着SDN网络的快速发展，对SDN网络进行有效的网络测量变得越来越重要。SDN网络的构架与传统的TCP / IP网络完全不同。这使得传统的端到端网络测量工具对于SDN网络都不再适用。为了在SDN构架下实现端到端的网络测量，本文提出一种新的SDN网络主动测量机制。这种机制以主动测量为目的，依据SDN网络的新型构架，对SDN协议和交换机进行了扩展完成相应测试功能。仿真结果表明，该机制可以获得准确的网络测量结果，并且具有良好的可扩展性。 |

| A New Active End-to-end SDN Network Measurement Mechanism |
|
|
| Abstract:SDN is a new network architecture proposed by Stanford University. The kernel principle of SDN is that separating the control plane and the data plane of the network. With the rapid development of the SDN network, the research of efficient measurement mechanism on SDN network becomes more and more important. The unique features of SDN network make the measurement and monitoring techniques on SDN network quite different from those on traditional TCP/IP network. Based on the fully use of the characteristics of SDN, we construct a new active SDN network measurement mechanism to measure the end-to-end path performance of the network. This mechanism takes the active SDN network measurement as the goal by extending the SDN protocol and the SDN switches. The simulation shows the mechanism can provide accurate network measurement results. |
