Abstract
PCP (Phantom Circuit Protocol) is a mechanism that provides a guaranteed-bandwidth transport mechanism in IP networks. It includes an effective Call Admission Control (CAC) protocol and operates ona per call basis, as in circuit switched networks. In this respect PCP presents the same capabilities as RSVP, but, unlike RSVP, PCP is fully scalable since the CAC procedure is completely distributed, involves only network access points and does not require network routers to exchange any call set-up signaling. Up to now, the validity of the mechanism has been demonstrated with respect to Constant Bit Rate traffic. In this paper we show how PCP operation can be extended to Variable Bit Rate traffic. Our approach is fully compatible with other Differentiated Services since a proper interaction among the new traffic aggregate and the other traffic can be defined according to the PHBs description rules. 1. Introduction The Internet is emerging as an alternative to Asynchronous Transfer Mode (...
