Embodiment Construction

[0036] All features disclosed in this specification, or steps in all methods or processes disclosed, may not be combined in any way. Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0037] Such as figure 1 As shown, the overall steps of the topological link discovery method are:

[0038] 1) The user enters the information required for link discovery; the information includes: SNMP-related information and subnet information that needs to discover links;

[0039] 2) Discover devices and classify and cache devices. Devices to be discovered include routers, switches, hosts, etc.;

[0040] 3), build all switch devices into a forest structure through the STP protocol, and set uplink ...

Abstract

The invention provides a general topological link accurate discovery method which comprises the following steps: 1) a user records a link to discover required information; 2) equipment is found, and classification and caching are performed on the equipment; 3) all switch equipment is built as a forest structure through a STP protocol, and an upstream port and a downstream port of each switch in the forest structure are arranged; 4) each tree in the forest structure is traversed for link analysis of a layer-2 switch, wherein the link analysis includes a link from a switch to a switch, a link from a switch to a mainframe and a link from a switch to a router; 5) a link from a layer-3 switch to the mainframe is calculated; and 6) a link from a router to a router is calculated. The method provided by the invention has high versatility, is adopted to raise accuracy, and is especially suitable for layer-2 and layer-3 topology link.

Description

technical field [0001] The invention relates to the field of IT operation and maintenance, in particular to a method for accurately discovering universal topological links. Background technique [0002] With the increasing scale of the network, the network environment of enterprises is becoming more and more complex, and there are more and more network devices, which have higher requirements for network management. [0003] The main purpose of network topology discovery is to obtain and maintain the existence information of network nodes and the link relationship information between them, and draw the entire network topology map on this basis. Network managers can quickly locate faulty nodes on the basis of topology diagrams. Existing topological link discovery methods are not accurate enough, and their versatility is not strong. Contents of the invention [0004] The present invention provides a general method for accurately discovering topological links, which not only...
