Problems solved by technology

The above topology collection methods can only obtain correct network topology information in the next collection cycle or after the collection is manually triggered
[0006] In addition, topology collection can also adopt a method based on retransmission / response, but this method will greatly increase the traffic of the network; and increase the processing load of each network device, especially the network topology collection device

Embodiment Construction

[0029] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0030] Figure 1A It is a schematic structural diagram of the network topology collection system realized in the two-layer network environment of the present invention. The remote network management system 11 designates an Ethernet switch in 12 in a certain network range (cluster) through the network 10 as the command node 13, which is equivalent to the management equipment in the cluster, and the unified management of the entire cluster network and the establishment of the cluster, Maintenance, and as a network topology collection device, responsible for collecting network topology information, and notifying the network management system 11 of the collected network topology information through the network 10; the cluster also includes a switch as a backup node 14, when the command node 13 fails , can take over the centralized management ...

Abstract

The system comprises several network devices. One of the network devices is appointed as a network topology collection device for initiating the topology collection request; other network devices are used to send their topology information to the network topology collection device by way of topology collection response; when a network device change its topology information, it triggers a relevant topology collection renew message, and the network topology collection device renews the relevant network topology information according to said topology collection response and topology collection renew message.

Description

technical field [0001] The invention relates to a network communication management system, in particular to a network topology collection system and corresponding network equipment. Background technique [0002] With the rapid development of network technology, the scale and scope of the network are expanding day by day, and the management problems of network equipment are becoming more and more prominent; topology discovery and topology collection management of network equipment is a hot spot in the new generation of network management technology. [0003] Topology Discovery: It aims to discover the information of adjacent network devices directly connected to this network device (such as device type, software and hardware version, port information, etc.), and the network device regularly sends topology discovery messages to directly connected adjacent network devices. At the same time, it receives the topology discovery message from the adjacent network device, extracts th...
