Research and Implementation on Auto Checking Port-Problem Based on Switch In ATC

By studying the eventual reasons of network failure related to switch port connectivity in double-network-double-switch architecture in ATC system and analyzing the inefficiency of manually checking and the disadvantage of traditional method on inspecting network failure based on address forwarding table, a solution to auto inspecting switch port failure based on SNMP and ICMP is proposed, and the detailed design to inspect switch port in double-network-double-switch is mentioned. It’s proved by the application results of configuration management of the ATC (Air Traffic Control) system that, the method not only is able to find switch port failure in the network simply and rapidly , but also to find failure reason accurately.
