A network card status monitoring and address switching method for a prefectural-county integrated network architecture

Abstract

The invention discloses a network card state monitoring and address switching method of the integrated network architecture of prefectures and counties. The county adjustment point sends an ICMP message to the local exchange and receives the ICMP response message, and all nodes can accurately judge the network card state of the node. , and switch the communication address of the node according to the state of the network card to realize the redundancy and mutual backup of the network; at the same time, by sending an ICMP message to the local (designated) switch and receiving an ICMP response message, the county adjustment point can judge the node According to the connection status of the local survey, switch the communication address of this node according to the connection status, so as to ensure that only one link between the local survey and the county regulation point is working normally, and the system nodes can still communicate normally, so as to realize the integration of districts and counties The network redundancy and mutual backup on the system network architecture has a good application prospect.

Description

technical field [0001] The invention relates to a network card state monitoring and address switching method suitable for the network framework of the integrated system of prefectures and counties, and belongs to the technical field of electric power dispatching automation. Background technique [0002] In the prefectural-county integrated system, in order to provide the reliability of network communication, two network cards are generally installed on the server node to connect two switches. For communication, instead of the traditional communication directly through the switch, when the network card or communication line connection fails and the communication is abnormal, the communication link needs to be switched to the backup network card for communication. However, the current network card status monitoring program can only monitor The connection state between the local node and the local exchange cannot be monitored when the connection between the local node and the r...

Problems solved by technology

[0004] The purpose of the present invention is to overcome the situation that the communication link between the local dispatch and the county dispatch may fail or be abnormal in the integrated system of prefectures and counties. Although the county regulation point can solve the abnormality of the intermediate link, it cannot detect the abnormal communication problems, problems that cannot be monitored in real time
