摘　　要：随着电信传统网络向NFV虚拟化网络的转型和全面演进,虚拟化网络性能分析和优化成为网络运维的重大任务和挑战之一。鉴于ping、iperf等传统的IP网络性能检测工具以及华为公司的IP染色技术存在的缺点和问题,本文提出一种基于软探针的NFV虚拟网络时延计算方法,通过构建两个虚拟机之间完整的端到端的IP路径,选择在4个关键节点放置软探针获取和汇总目标业务流量,通过哈希算法识别、统计流经4个关键节点的IP报文,根据各节点的计数及时间戳在沿途各节点的变化情况,计算出网络时延。With the transformation and comprehensive evolution from traditional telecommunications networks to NFV virtualized networks,performance analysis and optimization of virtualized networks have become one of the major tasks and challenges in network operation and maintenance.Considering the shortcomings and problems of traditional IP network performance detection tools such as ping and iperf,as well as Huawei̓s IP coloring technology,this paper proposes a soft probe based NFV virtual network latency calculation method.By constructing a complete end-to-end IP path between two virtual machines,selecting four key nodes to place soft probes to obtain and summarize target business traffic,identifying and counting IP packets flowing through the four key nodes using a hash algorithm,and calculating network latency based on the changes in the count and timestamp of each node along the way.
