Abstract

The invention discloses a data transmission method, device, and computer-readable storage medium, and relates to the technical field of data communication. The method includes: dividing an interface of a flexible Ethernet into multiple pipelines in a time-division multiplexing manner; Select one or more pipes among multiple pipes as public pipes, and other pipes as dedicated pipes. Each public pipe is used for data transmission of one or more users, and each dedicated pipe is used for data transmission of one user; Bandwidth requirements Select one or more dedicated pipes, the total bandwidth of the selected dedicated pipes is less than the user's bandwidth demand, and the user's remaining bandwidth demand is less than the bandwidth of each dedicated pipe; select a public pipe according to the user's remaining bandwidth demand; use The selected dedicated pipe and public pipe are used for data transmission of the user. The invention can reduce the waste of flexible Ethernet interface bandwidth.

Description

technical field [0001] The present invention relates to the technical field of data communication, in particular to a data transmission method, device and computer-readable storage medium. Background technique [0002] Flexible Ethernet (Flexible Ethernet, FLEXE for short) is a new Ethernet technology emerging in recent years. FLEXE is defined as the middle layer between the second layer of Ethernet (media access controller (MAC)) and the first layer (physical layer (PHY)), and divides the large pipeline of Ethernet into 10G, 40G, etc. Small pipes to meet the needs of enterprises and carriers for variable Ethernet speeds. [0003] The advantage of FLEXE is that it can provide users with flexible bandwidth hard pipes, saving bandwidth resources and ensuring user security at the same time. However, based on the existing architecture, the minimum granularity of FLEXE is 5GE, and bandwidth can only be allocated in integer multiples of 5GE granularity. Therefore, bandwidth req...
