【摘要】 研究了分布式网络测量基础架构(DNMAI),在此基础上探讨了分布式网络测量探针的时钟同步、端到端时延测量、TCP/IP协议效率和网络接口数据吞吐量等关键技术问题,并针对这些问题提出了相应解决办法。作为这些关键技术的实现,最后提出了分布式网络测量探针的分层设计方案。实验证明,该方案具有可移植性强、可靠性高的优点。更多还原

【Abstract】 The Distributed Network Measurement and Analysis Infrastructure (DNMAI) provide a framework in which we build a network measurement probe.DNMAI is discussed along with the key design decisions to solve the problems such as clock synchronization,end-to-end delay measurement,TCP/IP protocol efficiency and network adapter throughput inherent in building a network measurement probe.Finally,our distributed network measurement probe and its framework are presented,in which those key technologies mentioned above are realized.It is proved that this piece of solution is pretty reliable and easy to transplant.更多还原
