Virtual link establishing methods and related device

Abstract

The present application discloses a virtual link establishing method including: when an establishment request sent by a first OSD is received, setting, by a second OSD, the state of a second virtual link as a connecting state; authenticating read authentication content, wherein the authentication content is obtained by locally storing the authentication content of a real link; when the authentication is successful, setting the state of the second virtual link as a successful connection state; sending a confirmation message to the first OSD in order that the first OSD sets the state of the first virtual link as the successful connection state. The method, by multiplexing the authentication content in the real link, avoids a link that the first OSD sends the authentication content to the second OSD and reduces the number of interaction times when the virtual link is established, thereby improving the communication efficiency in the node. The present application also discloses another virtual link establishing method, two virtual link establishing systems, a device, and a computer readable storage media, 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 method for establishing a virtual link, another method for establishing a virtual link, two systems for establishing a virtual link, equipment, and a 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, the connection between each OSD A virtual connection will be established between them. [0003] After each OSD starts, it will establish...

AI Technical Summary

Problems solved by technology

However, in each step of establishing a virtual link, data interaction is required, which affects communication efficiency and increases network delay

In the storage system, it is necessary to establish a large number of virtual connections, which will cause the performance of the storage system to decline.
