网络管理操作模型的设计与分析

Design and Analysis of Operation Model in Network Management

提出了多级客户／服务器的网络管理操作模型，并就中间件的工作参数及工作方式进行了理论分析，给出了探询间隔的下限和一种基于队列长度的自适应探询方式，以ＴＭＩＳ（铁路运输管理系统）网管为实际背景，进行了计算机仿真模拟。该模型不仅能支持跨平台、分层次的网络管理操作，而且还优化了网管操作对网络延迟性能的影响。

In this paper,we proposed a multi layered client/server network management operation model,and theoretically analyzed the running parameters and the mode of the middleware.The minimum interval of polling as well as an adaptive polling mode based on the queue length were discussed.Based on the real TMIS network management,some simulating experiments have been done to confirm these theoretical conclusions.This model not only supports an operation for managing multi vendor and layered networks,but also optimizes the performance of network management.
