Issues of reserving resources in advance

Abstract

Resource management offers Quality-of-Service reliability for timecritical continuous-media applications. Currently existing resource management systems provide only means to reserve resources starting with the reservation attempt and lasting for an unspecified duration. However, for several applications such as video conferencing the ability to reserve the required resources in advance is needed. This paper explains a model for resource reservation in advance. We identify and discuss issues which must be resolved in resource reservation in advance systems. Some of the possible scenarios to be considered are described and we show how the resource reservation in advance scheme can be embedded in a general architecture.
