On Local CAC Schemes for Scalability of High-speed Networks

Abstract

Next generation networks are required to provide bandwidth on-demand for sessions with fine-time granularity. In this sense, centralized CAC (Connection Admission Control) approaches could suffer from scalability problems if the number of requests for connections is excessive. In this paper we investigate local CAC schemes where the admission decisions are performed at the network edges, based on precalculated admission quotas.
