Abstract
In a switch having input ports and output ports, a fast ring reservation arbitration is provided by grouping crosspoint units associated with an output port. If any of the crosspoint units of a group request the output port, a received token will be passed to crosspoint units within the group. If, on the other hand, none of the crosspoint units of a group request the output port, then a received token will bypass the group and be forwarded to a next group.
