Multistage network topology intelligent discovering and generation method and system based on hybrid protocols

Abstract

The invention provides a multistage network topology intelligent discovering and generation method and system based on hybrid protocols. The protocols adopted by the invention are mainly Fping and SNMP protocols, wherein the Fping protocol is mainly used for rapidly discovering equipment connected into or operated in a network, then the SNMP protocol is used for obtaining the information of the equipment, and the cascade relations or monitoring information of the network equipment are determined mainly by the obtained information. The multistage network topology intelligent discovering and generation method and system has the advantages that the high efficiency is realized in such a manner that according to a comparison result of ping and tracert protocols, the Fping protocol is used for rapidly discovering equipment connected into or operated in the network, and the time efficiency for discovering the equipment is improved; and the intelligence is realized in such a manner that the SNMP protocol is used for realizing the intelligence and automation of the network topology structure, and is further combined with system resource monitoring software to grasp the state of the whole computer network in real time.

Description

technical field [0001] The invention relates to computer network topology discovery, in particular to a hybrid protocol-based multi-level network topology intelligent discovery and generation method and system. Background technique [0002] Mixed protocol refers to the realization of computer network topology discovery on the basis of multiple protocols. Automatic discovery refers to: using protocols or related technologies to automatically detect devices in the network and identify their device types (computer hosts or servers, switches, routers, firewalls and other network devices). [0003] At present, the network topology discovery technology is mainly based on ping+SNMP technology or tracert+SMMP technology. These technical solutions mainly use ping or tracert technology to determine the connected or running devices in the network, and then obtain the connected or running devices through SNMP. information about operating equipment or monitoring those equipment. Among ...

Problems solved by technology

Among them, the ping protocol recovers the request through the ICMP protocol to detect the existence of the host. In this search process, it is necessary to wait for a host to connect to timeout or send back feedback information, and to ping a host at a time, so the time efficiency and work efficiency are low; tracert The protocol is mainly used to display the path taken by the data packet to the destination host, and display the time of each arrival node. It displays all the paths, node IPs and time spent by the data packet traversing the entire network. The disadvantages of this protocol are: System resources are wasted, and time efficiency and work efficiency are relatively low

[0004] To sum up, the efficiency of using ping or tracert technology to discover connected devices or running devices in the network is relatively low. For a large network, it takes a long time to traverse the entire network, and the time efficiency of network device discovery is relatively low. The two technical solutions are not advisable in practice
