Optical burst switching node with internal speedup

摘要

A multiple-plane OBS node comprises N input ports, N 1xN switches, N switching planes, N² FDLs, N optical couplers, and N output ports, each input port is connected with the input of a corresponding 1xN switches, the N outputs of each 1xN switch are connected with a corresponding input of each switching plane respectively, a corresponding output of each switching plane is connected with the input of the same corresponding optical coupler via a respective FDL, and each output port is connected with the output of a corresponding optical coupler, wherein N is an integer.
