基于SNMP的校园网管理系统的设计与实现

Design and implementation of network management system for campus based on SNMP

介绍了一个适合于校园网的基于SNMP的网络管理系统的设计与实现。以管理者/代理为模型,采用分层次的总体设计方案。在分析比较现有拓扑发现算法的基础上,给出一种改进的拓扑发现算法,融合二叉树排序策略和三层交换机发现策略。在实时性能参数采集分析的基础上,结合概率论与数理统计的思想,建立了一元线性回归模型,对性能参数进行有效的区间预测。系统不仅设计了网络的拓扑结构发现及显示、配置管理、性能管理等核心功能,更针对性地设计了网络性能预测、流量排序、病毒及非法软件检测等功能。

This paper describes the design and implementation of a network management system based on SNMP, which is suited for campuses. The system takes manager/agent models and use hierarchical design program. After analyzing the existing topology discovery algorithm, the paper proposes an improved topology discovery algorithm, which integrates strategies of binary sort tree and 3-layer switches discovery. In order to execute effective range forecast, the paper establishes a linear regression model integrating mathematical statistics theory, on the basis of real-time acquisition and analysis to performance parameters. The system not only designs the network topology discovery and display, configuration management, performance management and other core functionality, but also designs the network performance prediction, flow sorting, viruses and illegal software testing capabilities more targeted.
