Rate-controlled static-priority queueing

The authors propose a service discipline, called the rate-controlled static-priority (RCSP) queuing discipline, that provides throughput, delay, delay jitter, and loss free guarantees in a connection-oriented packet-switching network. The RCSP queuing discipline avoids both time-framing and sorted priority queues; it achieves flexibility in the allocation of delay and bandwidth, as well as simplicity of implementation. The key idea is to separate rate-control and delay-control functions in the design of the server. Applying this separation of functions results in a class of service disciplines of which RCSP is an instance
