public class CrossbarSwitch extends BasicSwitch
CommunicationAspect that, when its
BasicSwitch.sendToken(Receiver, Receiver, Token) method is called, delays
the delivery of the specified token to the specified receiver
according to a delays on input buffers, delays on output buffers
and delays in the switch fabric of a crossbar switch. This actor is
used the same way as the BasicSwitch; just the switch fabric
implemented here is different. I.e. this switch can potentially exhibit
better throughput performance as some tokens can be processed in parallel
by the switch fabric. For more information on how a crossbar switch works
please refer to the

Switch fabric queues for every output port.

Queue that stores tokens that have been put into the input queue but
cannot be processed by the switch fabric because the crossbar switch
for this connection is busy.
