基于P2P的分布式网络故障监测系统的研究 摘 要 随着网络技术的快速发展，网络规模不断扩大，网络维护变得日益复杂，传统网络故障监测模型已不能适应当前网络对故障监测的需求。本文将P2P技术与分布式网络故障监测技术相结合，尝试采用一种基于P2P技术的分布式网络故障监测模型，以适应目前大规模、复杂、动态的网络在网络故障监测方面的需求。主要工作包括： 首先，本文分析了大规模、异构网络环境对传统故障监测系统带来的问题，针对P2P技术和分布式故障监测系统的实现方法和技术难点展开研究。 其次，设计了基于P2P的网络故障监测系统，新系统分为P2P网络平台模块、网络故障监测模块和故障数据存储模块三个模块。采用Sun微系统对等网络标准， Research Of Distributed Network Fault Monitoring System Based On P2p ABSTRACT With the rapid development of network technology，the scale of network is expanding continuously, so the requirements of network fault monitoring is becoming more and more complex.The traditional network fault monitoring system no longer satisfies current network’s requirements for fault monitoring.This paper combined P2P technology with distributed network fault monitoring, try to use distributed network fault monitoring based on P2P,which adapt to the requirement of the current large-scale,complex,dynamic network.The main tasks are: Firstly,the problem of traditional network fault monitoring system for large scale and haterogeneous network envirment are analyzed,ltimate principle and difficult points of the P2P technology and distributed network fault monitoring system are also studied. Secondly,the newwork fault monitoring system based on P2P is designed,and the new system is divided into P2P network platform module、network fault monitoring module and fault data storage module.The P2P network platform module is realized by Sun Microsystems JXTA standard;In the realization of network fault monitoring module, the function of fault data acquistion in the module is realized by SNMPs trap alarm pattern and rolling mechanism, the filtering function for fault data is realized by the method which combing with Drools tool which based on Java and MIB threshold adjustment ;the UDP buffer overflow paoblems is sovled by the working pattern of double tasks when receiving SNMP Trap message; The fault data storage module is designed and implemented with database of Microsoft SQL Server2000.
