Method and apparatus for performing group switching in dense wavelength division multiplexing optical networks |
摘要 |
Method and apparatus for performing group switching in DWDM optical networks are described. One embodiment is an N x N three-stage group connector with N inputs and N outputs, wherein the N outputs are divided into r output groups, each group including n outputs such that r = N / n . The group connector comprises a first stage comprising r n x m crossbar switch modules, wherein m ‰¥ n-1; a second stage comprising m r x r crossbar switch modules; and a third stage comprising r M x N concentrator switch modules.
