ABSTRACT:
A method is described to operate a crossbar switch comprising a crossbar fabric with N sending and M receiving ports, with port cards connected to at least one sending and/or receiving port each of the crossbar fabric, said crossbar switch further comprising a control unit connected with the port cards via discrete control channel links, wherein C ports are clustered on a single receiving port card so that such a receiving port card in a single time-step can receive up to C data cells from C sending port cards simultaneously. According to said method the control channel links are used to relay up to C acknowledgements between at least one receiving port card and at least one sending port card.
