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

Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0023] In the network card status monitoring and address switching method of the prefecture-county integrated network architecture of the present invention, the county regulation point can judge the connection status between the local node and the local survey, and switch the communication address of the local node according to the connection status, so as to ensure that the local survey and local survey When only one link between the county regulation points works normally, the system nodes can still communicate normally, realizing network redundancy and mutual backup on the network architecture of the integrated system of prefectures and counties, such as figure 1 As shown, it specifically inc...

Abstract

The invention discloses a network interface card state monitoring and address switching method of a region-county integrated network architecture. County scheduling node send ICMP messages to local switches and receive ICMP response messages, and all nodes can accurately determine the network interface card states of local nodes and switching the communication addresses of the nodes according to the network interface card states so as to realize redundancy mutual backup of networks; and at the same time, through sending the ICMP messages to region scheduling (specific) switches and receiving the ICMP response messages, the county scheduling nodes can determine the connection states of the local nodes with region scheduling nodes and switching the communication addresses of the local nodes according to the connection states so as to ensure that system nodes can still communicate with each other normally even if only one link works normally between the region scheduling nodes and the county scheduling nodes, and realize the network redundancy mutual backup on the region-county integrated system network architecture. Therefore, the method provided by the invention has 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...
