WE6:实时高效Windows平台IPv6网络模拟器设计与实现


□ 李学杰 金志刚 戴居丰

  摘 要:IPv6网络需要新的网络协议和设备。在将新设备应用到实际环境前,需要大量的实验对设备和协议进行验证。网络模拟器是进行这类实验的有效工具。为此,设计了一种同时支持IPv6和IPv4协议的Windows平台网络模拟器:WE6(Windows-platform emulator IPv6)。可以实现对网络带宽、传输延迟、传输丢包率以及传输延迟抖动的控制和调节。在Cernet Ⅱ 上进行的实际使用表明,该网络模拟器可以对IPv6业务进行精确的实验环境控制,为协议和设备的开发与验证提供可靠的条件。

  Abstract:With the development of Internet, new protocols and network equipments are required to develop. It is necessary to test the new protocols and network equipments extensively before deployment. This paper proposed the design and implementation of RENEW, a useable and accurate network emulator which supported both IPv4 and IPv6 protocols. Besides, it also worked on Windows platform. InIPv6 testbed,it used RENEW to emulate various network characteristics and conditions including bandwidth, delay packet loss and jitter. Compared with the expected values, results were acceptable. Through implementation and experimentation study, it shows that RENEW does provide the real-time control and change on the parameters of IPv6 network conditions effectively and expediently on Windows. It also gives enough accuracy and more satisfactory convenience to the development and test work for the new protocols. ......
