Advance reservation of network resources for multimedia applications
To guarantee Quality of Services for continuous media like audio and video, intermediate nodes in networks must be able to reserve resources like buffer capacity, CPU time and bandwidth. Several methods have been introduced to verify that new connections can be accepted by the network without violating guarantees made for already established connections. One drawback of all proposed admission control algorithms is that they accept the reservation only at connection establishment time. It is not possible to reserve resources in advance. This paper introduces an algorithm that allows the user to reserve the desired QOS in advance. The paper further describes how the signalling of advance reservation can be realized using the Internet Stream Protocol ST-2.
