Problems solved by technology

[0007] The embodiment of the present invention provides a system maintenance method and a network switching device to solve the problem that the existing HA solution must use a manual connection heartbeat line, which is not convenient to implement, and the existing HA solution has too many heartbeat data packets. Many, leading to the problem of increasing the possibility of packet loss, and the problem that HA cannot be realized between working devices with different operating systems

Embodiment Construction

[0026] Embodiments of the present invention provide a system maintenance method and a network switching device, which are used to avoid connecting heartbeat wires, so that the HA scheme is easy to implement, and at the same time, the stability and availability of the HA scheme are improved.

[0027] see image 3 , a system maintenance method provided by an embodiment of the present invention includes:

[0028] S301: The network switching device determines that the heartbeat data packet sent by the active working device through the service link established with the network switching device has not been received within a preset time, and determines that the active working device has failed; and, The network switching device receives the heartbeat data packet sent by the standby working device through the established service link with the network switching device, and determines the normal working standby working device according to the received heartbeat data packet.

Abstract

Embodiments of the present invention provide a system maintenance method and a network switching device, which are used to avoid connecting a heartbeat line, reduce packet loss of heartbeat data packets, and implement a cross-operating system HA solution. The method includes: the network switching device determines that the heartbeat data packet sent by the primary working device through the established service link with the network switching device is not received within a preset time, and determines that the primary working device is faulty; and , the network switching device receives the heartbeat data packet sent by the standby working device through the established service link with the network switching device, and determines the normal running standby working device according to the received heartbeat data packet; A backup working device for taking over the main working device is determined from the normally operating backup working devices; the network switching device sends service data to the backup working device for taking over the main working device.

Description

technical field [0001] The invention relates to the technical field of electronic computers, in particular to a system maintenance method and network switching equipment. Background technique [0002] Existing high availability (High Availability, HA) solutions for clusters or dual-machines are all implemented based on the heartbeat protocol. The heartbeat protocol is used to keep the communication network between the active and standby working devices active at all times to ensure that any network outages or device crashes can be detected. The implementation method of the existing heartbeat protocol is: the active working device periodically sends heartbeat signals to the standby device, and if the standby working device does not receive a fixed number of heartbeat signals, it considers the active working device to be faulty and starts switching. [0003] There are two traditional HA schemes: the first one is as figure 1 As shown in the figure, the two working devices are...
