摘　　要：随着当今社会网络的日益普及，网络嗅探（分析）器已经被广发的应用与模拟网络通信以及测试网络性能等等工作中。而目前对于数据包捕捉函数库Libpcap的应用主要集中与在网络分析器中，相对于对截获的数据包进行发送等功能的工具相对来说较少。本文就实现一个基于Libpcap及原石套接字的数据包发射器，同时支持多重格式读写，进而在大容量数据包的网络性能测试以及定时、快速发包准确性等应用方面进行了优化的设计。With the growing popularity of social networks today,network sniffer （analysis） is already being widely distributed application and network traffic simulation and test network performance,etc.work.At present,the packet capture library for applications Libpcap mainly with the network analyzer, the relative of the intercepted data packets for transmission and other functions are relatively few tools.This article implements a socket-based Libpcap and the original stone packet transmitter supports both read and write multiple formats,and then large amounts of data packets in the network performance testing and timing accuracy applications such as fast contracting optimized design.
