One undesirable problem introduced by the optical multistage interconnection network is a crosstalk that is caused by coupling two signals within a switching element. To avoid a crosstalk, many approaches have been proposed such as time domain and space domain approaches. Because the messages should be partitioned into several groups to send to the network, window method is used to find out which messages should not be in the same group. In this paper fast window method based on bitwise operations (BWM) is represented. This algorithm reduces the execution time approximately more than ten times compared with previous algorithms.
