Embodiment Construction

[0035] The technical solutions in the embodiments of the present application will be described below with reference to the accompanying drawings in the embodiments of the present application.

[0036] The applicant's research has found that when costs or conditions are limited, such as in low-cost distributed network equipment, the backplanes are often connected through fewer links. Among them, only one link is formed between two boards or other communication components through their respective high-speed ports. If an abnormality occurs between the high-speed ports, the data channel between the two communication components or more communication components will be completely disconnected. , and the existing link repair methods usually use the principle of speed reduction repair and port disabling and re-enablement to repair the link. When a channel (Lane) between the ports in the link fails, the above two methods cannot be used. Realize the recovery of link communication functi...

Abstract

The present application provides a link restoration method, device, electronic equipment and storage medium, which belong to the technical field of communication. The method includes: when the link between the internal ports connected by two boards through the backplane is abnormal, splitting the link into n sub-links, where n is an integer greater than or equal to 2; b. Describe the effective total bandwidth of the n sub-links, and use the splitting mode corresponding to the n sub-links as the repairing mode to be selected; c. Repeat step a to step b after n is increased by a preset gradient value until the splitting out The effective total bandwidth of all the sub-links is smaller than the effective total bandwidth of all the sub-links split last time. Links can be repaired by determining sub-links capable of normal data transmission through gradient link splitting, which can repair the failure of some channels.

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular, to a link repair method, apparatus, electronic device, and storage medium. Background technique [0002] Existing low-end distributed network equipment is limited by cost. Usually, there are fewer backplane connections for communication between boards, and generally only one high-speed port is connected. In this case, if the high-speed port is abnormal, two The data channel between boards is completely disconnected, resulting in abnormal data forwarding. [0003] There are currently solutions, one is to try to repair the port by disabling and re-enabling the port, the other is to try to slow down the port to repair the port, but the repair capabilities of these two methods are limited, assuming one of the ports If the channel is faulty, no matter whether the port is disabled and then enabled, or the port is slowed down, the port cannot be repaired.
