摘　　要：分析传统网络管理集中式及分层次体系结构的缺陷,提出分布式网络管理的体系结构,把用于大规模集成电路故障诊断的系统级故障诊断算法ADSD应用到计算机网络故障诊断中。为了验证计算机网络分布式故障诊断的可行性,在NS中嵌入ADSD算法,模拟整个算法的执行,对算法的执行效率如诊断延时、报文流量进行分析。在此基础上对原算法进行改进,以减小算法对正常网络应用的影响。通过对SNMP的模拟实验,验证在网络管理中引入分布式故障诊断的可行性。This paper analyzes the innate disadvantages of centralized architecture and hierarchical architecture in traditional network management, and presents a new distributed architecture of network management. ADSD algorithm, which is originally used in digital large scale integrated circuit, is applied into management of computer network. To validate the feasibility of distributed fault diagnosis in network, ADSD is compiled into NS. The performance of this algorithm is analyzed, such as the delay of fault diagnoses and the traffic of message. The visual experimental results are presented. The algorithm is improved to reduce the effect in normal network applications. According to the simulation system, it can be concluded that the distributed architecture for network management is feasible.
