A virtual link reconstruction method and related device

Abstract

The present application discloses a virtual link reconstruction method, including: the first OSD resets the first virtual link to obtain the first initialized virtual link; when sending a message, performs session binding processing on the first initialized virtual link , get the new link session information and the first reconstructed virtual link; send the message and the new link session information to the second OSD, so that the second OSD can process the message, and conduct a session on the second virtual link according to the new link session information The rebinding process results in a second rebuilt virtual link. Realize the deletion of virtual links by resetting virtual links, and send new link session information while sending normal business messages, so that virtual links can be re-established between OSDs, reducing the number of interactions and improving network performance . The present application also discloses a virtual link reconstruction system, device and computer-readable storage medium, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a virtual link reconstruction method, reconstruction system, device and computer-readable storage medium. Background technique [0002] With the continuous development of storage technology, various storage devices appear. Among them, there is no shortage of storage systems based on OSD (Object-based Storage Device), in which there are multiple storage nodes, and multiple OSDs are set on each storage node. When running the storage system, each OSD runs in single-process mode, and all OSDs on a node share a TCP connection. However, in the program, in order to match the original code flow, a virtual connection needs to be used for processing, that is, each OSD Virtual connections will be established between them, and there will be many virtual connections in one node. [0003] When an exception occurs, the real link will be disconnected, that is, the TCP connectio...

Problems solved by technology

At the same time, after the network is restored, it is necessary to re-establish links between OSDs, and OSDs will receive a large number of virtual link establishment messages. In both cases, a large number of messages will block network transmission and may cause message processing Mis-established link exceptions, etc.

In general, when the network is abnormal, the virtual link needs to be rebuilt, and the existing rebuilding operation needs to send a large number of messages when the network is restored, causing network message congestion and affecting network performance.
