Description

technical field [0001] The invention relates to the field of optical interconnection networks, in particular to a network interconnection device for non-buffer optical interconnection networks. Background technique [0002] In a traditional electrical interconnection network, the power consumption generated by message transmission, buffering and switching grows quadratically with the increase of data transmission rate. Therefore, the interconnection network based on electrical interconnection has been difficult to meet the communication requirements of high-performance computers. In the optical interconnection network, light waves are used as information carriers, which have the advantages of low power consumption, high interconnection density, and low transmission delay. Optical interconnection network has been widely accepted as an effective method to improve the bandwidth bottleneck of communication system, and it opens up a new way for the design of interconnection netw...
