Abstract

The invention provides a bandwidth allocation device and a method. Each output port of an MAC (Media Access Control) outputs a to-be-allocated bandwidth, a CPU (Central Processing Unit) controls a path between a host-end serial bus channel and a line-end serial bus channel of a PHY (Physical Layer) to be switched on or switched off according to a configuration requirement, and the PHY allocates and outputs the to-be-allocated bandwidth. A group of line end serial bus channels of the PHY and a group of serial bus channels in at least two groups of line end serial bus channels share a group of host end serial bus channels, and a second port packaged by the line end serial bus channels of the PHY is compatible with a first type of optical module and a second type of optical module. Therefore, the path between the host end serial bus channel and the line end serial bus channel is controlled to be switched on or switched off through the CPU, and the high bandwidth utilization rate under the condition of low cost can be achieved.

Description

technical field [0001] The present invention relates to the technical field of wireless communication, in particular to a bandwidth allocation device and method. Background technique [0002] With the commercialization of 5G, coupled with the rapid development of cloud computing, big data, Internet of Things, artificial intelligence and other information technologies and the digital transformation of traditional industries, as well as the rapid construction of data centers, the number of optical modules interconnected within and between data centers and bandwidth requirements are growing explosively. Ports on access switches and aggregation switches have transitioned from 40G to 100G or higher bandwidth port interconnection; interconnection ports on data center switches have gradually transitioned from 100G to 200G and 400G. Since 2019, both 200G and 400G are growing at a rate exceeding 100G, especially the demand for 400G. [0003] Based on the current market demand, the ...
