ABSTRACT:
A method and apparatus for supporting end-to-end quality of service (QoS) reservations for an implicit reservations model are provided. The invention teaches how to implement implicit resource reservations using the open-standard Resource and Admission Control Function (RACF). A request for resources for a given reservation between an originating and a terminating point in a network is received. A central controller for that domain processes the request for a given domain to determine whether routes for said reservation are available and whether necessary bandwidth for said reservation is available. An implicit reservation and a release of the bandwidth are respectively accomplished with a specific number of messages.If the routes and bandwidth are available, the reservation for the given domain is confirmed and the reservation request is passed to another central controller for a next domain having resources required to satisfy the reservation request.
