网络的性能管理可以有效地提高网络的可维护性,为网络的规划提供依据。综合业务局域网的性能管理是当今国际上大力研究的一个热门课题。本文对一个具有34Mb/s传输速率的综合业务环形网(ISR)的性能管理进行了研究。ISR可以传输计算机数据、话音、传真、监控电视和会议电视。性能管理用到的统计数据采用轮询和报告两种方式来采集。环上的主结点把采集到的数据定期送往一个称为管理站的计算机。在管理站上的管理员可以随时浏览网络的原始数据和由原始数据综合得到更加直观、更加符合人们习惯的综合数据,管理员还可以利用管理系统中的专家系统对网络的性能进行评估,得到网络规划方面的建议。
The performance management of the network can effectively improve the maintainability of the network and provide the basis for the network planning. Integrated business LAN performance management is a hot topic in the current international study. This paper studies the performance management of an ISR with a transmission rate of 34Mb / s. The ISR can transfer computer data, voice, fax, surveillance TV and conference television. The statistics used in performance management are collected in two ways: polling and reporting. The primary node on the ring sends the collected data on a regular basis to a computer called a management station. Administrators at the management station can browse the network’s raw data at any time and from the original data more comprehensive and more intuitive, more consistent with the people’s comprehensive data, administrators can also use the management system of expert systems to assess the performance of the network, get Network planning advice.
