Embodiment Construction

[0048] In view of the problem in the prior art that it takes a long time to directly reset the service card, which seriously affects the user experience, the embodiment of the present invention provides a PCIE channel maintenance method, which is applied to distributed network equipment. The distributed network equipment includes A main control card and at least one service card, the main control card and at least one service card are respectively connected through a PCIE channel and an Ethernet channel, and the flow of the method is as follows figure 1 As shown, the execution steps are as follows:

[0049] S11: Monitor whether a heartbeat signal sent by at least one service card through the connected PCIE channel and the Ethernet channel is received within the first set time period.

[0050]A heartbeat detection mechanism is set between the main control card and at least one service card, and at least one service card can send heartbeat signals through the connected PCIE chan...

Abstract

The invention discloses a PCIE (Peripheral Component Interconnect Express) channel maintenance method and device. The method comprises the following steps: monitoring whether heartbeat signals sent byat least one service card through a PCIE channel and an Ethernet channel which are connected respectively are received within a first set time length or not; if the heartbeat signal sent by the firstservice card in the at least one service card through the connected first PCIE is not received within the first set duration, receiving the heartbeat signal sent by the first service card through theconnected first Ethernet channel, if so, determining that the first PCIE channel is abnormal and the first Ethernet channel is normal; and repairing the first PCIE channel according to a preset step-by-step repair strategy. The scheme can greatly improve the user experience.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and device for overhauling a high-speed serial computer expansion bus standard (Peripheral Component Interconnect Express, PCIE) channel. Background technique [0002] With the rapid development of network technology, distributed network devices are used more and more widely. A distributed network device usually includes a main control card and at least one service card, wherein two physical channels, PCIE channel and Ethernet channel, are set between the main control card and each service card, and the two physical channels are used for different the use of. In order to ensure the reliability of distributed network devices, it is necessary to detect the correctness of each physical channel and repair it in time when abnormalities are detected. [0003] At present, the maintenance method of the PCIE channel mainly relies on the detection of the heartbeat mechanis...
