New approach of resource management to provide integrated services over ATM networks

The cooperative action between RSVP and some protocols performed on ATM networks, is one of problems that should be solved to provide integrated services over ATM networks discussed in IETF. In this paper, after describing some schemes that map RSVP into these protocols to reserve resources over ATM networks, we compare these schemes and point out some problems therein. Next, we propose a new approach referred to as “the direct lookup approach” to improve these schemes. The new approach removes overhead by the mapping between RSVP and protocols performed on ATM networks, and control messages of RSVP on ATM networks are directly examined. Finally, we discuss some issues for the implementation of this new approach
