Allocation of resources within a multistage buffered crossbar switch with internal credit based flow control was proposed in order to support quality of service objectives for different traffic classes in the Internet. The flow control system in the single-stage buffered crossbar switch was analyzed to develop a technique for determining the required amount of resource in a single-stage switch. An alternative flow control scheme that aggregates traffic was also proposed to specific cross-point buffers into logical queues at the output of each stage. It was shown that flow aggregation saves both bandwidth and number of credits as well as simplifies the multistage switch control system.
