Abstract
A crossbar switch is provided that can allocate output port bandwidth both among multiple classes of service and among input ports. In one implementation, there are two scheduling stages that may be implemented together. One scheduling stage can select traffic for output based on class of service whereas the other scheduling stage may perform a further selection based on destination output port. This allows greater flexibility in managing congestion and allocating limited available bandwidth.
