System maintenance method and network switching equipment

Abstract

The embodiment of the invention provides a system maintenance method and network switching equipment, which is used for avoiding connection of heartbeat lines, reducing loss of heartbeat data packets and realizing a cross-operating system HA scheme. The method comprises the steps that main working equipment is determined to break down if the network switching equipment is determined not to receive a heartbeat data packet sent by the main working equipment through a service link established between the main working equipment and the network switching equipment within a preset period of time; the network switching device receives a heartbeat data packet sent by standby working equipment through a service link established between the standby working equipment and the network switching equipment, and normally operating standby working equipment is determined according to the received heartbeat data packet; the network switching equipment determines standby working equipment used for replacing the main working equipment from the normally operating standby working equipment; and the network switching equipment sends service data to the standby working equipment used for replacing the main working equipment.

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...

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
