Synthesis of an output buffer management scheme in a switching system for multimedia communications

A major problem is how to determine buffer capacity, and how to synthesize a service quality control scheme for both delay and loss probability so as to satisfy multiple grades of service requirements. This is because in multimedia communications systems, each medium may have its own grade of service requirements, and these requirements may differ greatly from medium to medium. A synthesis method is proposed based on a conservation law for an M/D/1 queue with finite capacity. The necessity of a buffer management scheme in a multimedia environment is discussed. The achievability of mean delay performance is examined on the basis of a conservation law for an M/D/1 queue with finite capacity. A synthesis of the buffer management scheme that satisfies both delay and loss probability requirements is examined
