摘　　要：现有IP流重放系统大多基于纯软件或昂贵的网络测试设备,存在着性能低、时间戳精度不够及成本过高等诸多问题。提出并实现了一种基于Cavium公司的CN38XX系列多核网络处理芯片的网卡、运行于Linux主机和网卡芯片的在线改包发包系统,该系统具有高精度高性能的IP流修改、重放的功能。Existing IP stream replay systems are mainly based on pure software or expensive network testing equipment,there are low-performance,non-precision timestamp,high cost and many other drawbacks.In this paper we propose and implement a solution of a high-performance high-precision IP stream modifying and replay system,which is based on a network adapter using Cavium＇s multi-core processor CN38XX,as well as an online packet modifying and sending program,running on a Linux host and the network adapter.
