Problems solved by technology

Confirm the health of devices and links by sending and receiving health check messages synchronously. During this process, the PCIE bus needs to undertake a large number of message sending and receiving tasks, which is a heavy burden. Processing and sending and receiving a large number of health check messages will easily cause the CPU to be busy and affect the Handling of other business

Abstract

The present application provides a link health check method and device. By using the coprocessor to construct a large number of health check messages with a fixed mode, the task of sending the message is handed over to the coprocessor for execution. The CPU is only responsible for receiving the health check message, and is no longer responsible for sending the health check message. Avoid the main control CPU from being in a busy state due to processing a large number of message sending and receiving, and at the same time reduce the burden of sending packets on the PCIE channel between the CPU and the switching chip.

Description

technical field [0001] The present application relates to the technical field of the Internet, and in particular to a link health check method and device. Background technique [0002] Link health check refers to the check of the health status of the communication link between the local end and each peer end. This check can ensure that the traffic will not be forwarded to the faulty link, and the distribution of business traffic can be adjusted according to the check result. Network service quality provides the necessary guarantee. [0003] like figure 1 As shown in FIG. 2 , it is a schematic structural diagram of a network device. There are multiple switching chips, and these switching chips are located in a single board, and the single board is connected to the main control CPU through a PCIE bus. In the traditional solution, on the one hand, the switch chip receives the health check message sent by the external device, and sends the health check message to the main cont...
