摘要
Disclosed is an optical switching system with a combined space and wavelength division multiplex based on the repeated contention technique. The present invention has effects on high capacity in required in the optical switch module, by performing the contention resolution over a two consecutive cell time slot which repeatedly employs the present and previous state information. According to the present invention, the input cells make use of a switching opportunity two times. As a result, the present invention maintains the desired probability of cell loss, keeping up the state values L small. Also, the present invention can decrease the number of filters because it is possible to decrease the number of wavelength used for the wavelength conversion. Furthermore, the present invention has an effect on the high capacity based on the extension of the optical switch modules.
