Abstract

Networking BroadBand Services (NBBS) is IBM's control point architecture for next generation high‐speed packet‐ or cell‐switched networks and is implemented in a family of network switching nodes. In this paper, we describe the traffic estimation and dynamic bandwidth adaptation function of the NBBS architecture. The dynamic Connection Admission Control (CAC) procedures we describe in this paper enable more efficient bandwidth management in high‐speed networks. The dynamic CAC procedures we propose rely on traffic identification at the access points to the network and adjustments in bandwidth allocated through the network. This framework allows the NBBS network to provide enhanced variable‐bit‐rate services for non‐stationary traffic sources in addition to providing standards compliant variable‐bit‐rate services based on deterministic rule‐based traffic descriptors. The traffic estimation methodology discussed here can also be used to devise easy‐to‐implement statistical conformance tests for Usage Parameter Control (UPC) mechanisms.
