The future Broadband-ISDN based on the Asynchronous Transfer Mode (ATM) has to cope with a vast variety of services with different bitrate and Quality of Service (QoS) requirements. Consequently, traffic control is essential to guarantee the negotiated QoS while allowing a high network utilization. One possible traffic control scheme is the Fast Reservation Protocol (FRP) which introduces a dynamic traffic control at the burst level enhancing the capabilities of the network to increase its utilization for highly burst.y traffic. In this paper we focus on the analysis of the two variants of the FRP. An analytical approach for an isolated switching node as well as for a whole reference connection is presented. The obtained results show a good agreement with simulation results. Finally, the analysis is used to compare the two variants of the FRP with respect to their key performance parameters.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
