一、概述 网络管理软件的功能是对网络进行性能监视、故障检测、配置、计费及安全等管理操作,所有这些操作都需要一个直观、友好的用户界面。所以,在网络管理系统软件中构造网络拓扑图是很有必要的。网络拓扑图的搜索是大多数网络管理系统的基本功能之一。目前,很多网络管理产品中已经实现了网络拓扑图的搜索,但实现的程度不同。 ●TRANSCEND:由3Com公司开发。该产品的自动搜索功能较简单。只能检测出当前局域网中的主机,不能确定各个主机的互联情况,不能确定主机的接口类型。该产品能对本公司的网络硬件设备产品进行较精确的搜索,能显示出其网络设备各个端口的状态。但对其它生产厂家生产的网络设备没有此功能。运行 I. Overview The function of network management software is to manage the network performance monitoring, fault detection, configuration, billing and security, all of which require an intuitive and user-friendly interface. Therefore, it is necessary to construct the network topology in the network management system software. Network topology search is one of the basic functions of most network management systems. Currently, many network management products have been achieved in the search of the network topology, but the degree of realization is different. ● TRANSCEND: Developed by 3Com. The product’s automatic search function is relatively simple. Can only detect the current LAN host, can not determine the interconnection of the host, can not determine the host interface type. The product of the company’s network hardware products for more accurate search, can show the status of each port of its network equipment. However, other manufacturers of network equipment does not have this feature. run
