摘　　要：为了进一步提高IP网络的传输性能,采用实测结果与业务数据统计分析相结合的方法,研究了IP网络设备在限速状态下对突发报文支持能力的差异,建立了信号源突发量、发送速率与网络设备缓存的线性模型,得出了无故障界面时,一定包长的时间间隔值。结果分析表明,该研究可推广应用于其他厂商路由器、交换机和网桥、集线器等设备,为精确测量网络设备端口限速服务质量保障能力提供了较好的基础性技术手段,对合理组网和规划网络服务质量保障措施具有指导意义。Difference of IP network equipment in supporting burst messages under rate limit state is researched,linear models of burst size of signal source,transmission rate,and network equipment cache are built,and time interval of a package length in case of a trouble-free interface is obtained in combination of measured results and statistic analysis of business data in order to further improve the transmission performance of IP network. The result analysis shows the research can be applied to routers,switches,network bridges,and hubs,etc. of other manufacturers,which provides superior fundamental technological means for accurately measuring the rate-limit quality assurance capacity of equipment ports,and has guiding significance for rational networking planning network service quality assurance measures.
