Embodiment Construction

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

[0036] The applicant's research found that when the cost or conditions are limited, for example, 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 there is an abnormality between the high-speed ports, the data channel between two or more communication components will be completely disconnected. , and the existing link repair methods usually use the principle of reducing speed repair and disabling and re-enabling the port to repair the link. When a channel (Lane) between ports in the link fails, the above two methods cannot Realize the restoration of the link communication function.

[0037] In order to solve the above...

Abstract

The invention provides a link repair method and a device, electronic equipment and a storage medium, and belongs to the technical field of communication. The method comprises the steps that when a link between internal ports, connected through a backboard, of two board cards is abnormal, splitting the link into n sub-links, and n is an integer larger than or equal to 2; b, recording effective total bandwidths of the n sub-links, and taking splitting modes corresponding to the n sub-links as to-be-selected repair modes; and c, adding a preset gradient value to n, and then repeatedly executing the steps a to b until the effective total bandwidth of all the split sub-links is smaller than the effective total bandwidth of all the split sub-links last time. The link is repaired by determining the repair mode of the sub-link capable of normally performing data transmission through gradient ground link splitting, and the situation that part of channels fail can be repaired.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular, to a link restoration method, device, electronic equipment, 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 cards. Generally, there is only one high-speed port connection. In this case, if the high-speed port is abnormal, it will cause two The data channel between boards is completely disconnected, resulting in abnormal data forwarding. [0003] Currently there are solutions, one is to try to repair the port by disabling and re-enabling the port, and the other is to try to reduce the speed of the port to repair the port, but the repair capabilities of these two methods are limited, assuming that one of the ports If the channel fails, the port cannot be repaired no matter whether the port is disabled and then en...
