摘要:: 网络拓扑的获取是网络管理的一个重要任务。传统的网络拓扑扫描无法实现拓扑的增量扫描，不能及时更新拓扑和响应管理者的操作。为了更实时快速地反映拓扑信息及其变化，文中提出了网络拓扑多端扫描的遍历机制，利用并行高效的网络多端遍历模型，通过SNMP收集网络的路由等状态信息，检测并控制节点的状态属性，采集准确的网络拓扑并存储。同时针对网络拓扑实时变化追踪对网络管理的即时要求，提出了网络拓扑档案的概念，并针对拓扑档案的更新、比对与输出等问题进行讨论

Abstract:: Acquiring network topology is an important task of the network management. The traditional network topology scanning can't achieve the increment scanning of the topology,can't update topology and response management operation timely. In order to reflect the real time information of topology and its alteration quickly,put forward a multiterminal scanning mechanism of the network topology, with the use of parallel and efficient multiterminal traversal model,collect routing state information of network via SNMP to detect and control the property of the nodes,get accurate network topology and keep stored. Meanwhile,due to the immediate requirements of net-work management for real-time changes tracking in network topology,the concept of the network topology archives is proposed,discus-sing about the updating,comparison and output of the topology archives as well
