A switch circuit based on switch channel

Abstract

The invention provides a switch circuit based on a switch channel, including a switch scheduling module, a storage management module, an input control module, an output control module, an input-output crossbar switch, a switch channel module, and a storage control module. The present invention takes the switch channel as the control center , exchange data with the input port and output port through the input and output crossbar switch, the exchange scheduling module completes the arbitration, distribution and recovery of the exchange channel unit, and the exchange channel module responds to the output port with the same storage data request multiple times to realize the data exchange Fast access, through the storage control module connected with large-capacity external memory, to achieve the storage requirements of large-capacity data buffer, the present invention combines store-and-forward, crossbar, high-speed buffer and other designs, exchange bandwidth, exchange delay and scalability are better than current technology.

Description

technical field [0001] The invention belongs to computer hardware technology and relates to a switching circuit based on switching channels. Background technique [0002] The communication and expansion of computer networks require switches to exchange data. Switching circuits generally include shared bus switching, shared storage switching, fully interconnected switching, and crossbar switching. Shared media switching circuits such as shared buses and shared storage are relatively inefficient. Both the switch and the crossbar switch need to occupy a relatively large internal memory, and the memory capacity limits the aggregation bandwidth of the switch. Contents of the invention [0003] The purpose of the present invention is to provide a switching circuit design circuit based on switching channels, which can expand multiple switching channels according to actual applications, realize parallel switching between multiple input and output ports, and effectively solve switc...
