- 摘要:
- 作为一种新型网络结构,软件定义网络(SDN)将数据转发平面与控制平面解耦合,实现了网络业务的可编程。而对网络性能参数的测量,是掌握一个网络运行状况的重要指标之一。在充分利用SDN网络特点的基础上,借鉴传统网络中对性能参数的定义及测量方法,结合主动测量与被动测量方法,对SDN网络中带宽、时延、丢包率、链路利用率等网络性能参数进行测量。仿真结果显示,文中实现的网络性能测量系统测量的数据与预期结果一致。
- Abstract:
- Software Defined Network(SDN)is an emerging network architecture, which decouples the control plane from data forwarding plane and realizes programmable network services. The measurement of network performance parameters is one of the most important indexes to master a network operation. Based on full use of the features of SDN, and referred the measurement methods and definitions about network performance parameters in traditional network, this paper adopts the combination of active measurement method and passive measurement method, and it realizes the measurement and analysis of bandwidth, delay, link utilization, packet loss rate of SDN. Simulation results show that the measured value by performance measurement system is consistent with expected result.
