基于云平台的高逼真链路仿真研究
Research on High-fidelity Link Emulation Based on Cloud Platform
摘要
Abstract
Aiming at the problem that the performance parameters of the virtual links cannot be emulated accurately in the OpenStack cloud platform,a method of high-fidelity link emulation is proposed.The virtual network nodes are emulated by multi-granularity virtualization technology,and the virtual links between virtual network nodes are constructed based on Software Defined Network(SDN).According to the location of the compute nodes where the virtual network nodes communicate,the intra-host link emulation and the inter-host link emulation are achieved respectively,so that the flexible configuration and automatic deployment of the virtual link performance parameters(bandwidth,delay and packet loss rate)are supported.The experimental results show that the method can accurately emulate the performance parameters of virtual links and improve the fidelity of link emulation.关键词
