Abstract: Modern networks are now capable of guaranteeing a consistent quality of service (QoS) to multimedia traffic streams. A number of major operating system vendors are also working hard to extend these guarantees into the end-system. In both cases, however, there remains the problem of determining a service rate sufficient to ensure the desired quality of service. Source modeling is not a sustainable approach in the network case and it is even less feasible to model the demands of multimedia applications. The ESPRIT measure project is successfully using on-line measurement and estimation to perform resource allocation for bursty traffic in ATM networks. In this paper we consider the applicability of the same theory to resource allocation in a multimedia operating system which offers QoS guarantees to its applications. !11
