Resource Reservation Scheme for Synchronized Distributed Multimedia Sessions.

摘要

Guarantees of services in a networked environment are provided by the proper allocation and utilization of network and system resources. In this paper, the authors propose a resource reservation scheme for a class of multimedia applications. They characterize this class of multimedia applications as synchronized distributed multimedia sessions (SDMS), which they believe represent a large number of multimedia applications. In addition to this particular class of applications, the reservation scheme also can be applied to other applications with synchronized resource requirements. Mechanisms are devised so that the scheme can find a feasible reservation whenever one exists, in contrast to existing protocols in which requests can fail unpredictably even when there is an available resource. Based upon a layer of resource abstraction, the scheme should work well with today's heterogeneous network environments.
