A bandwidth allocation technique for high speed networks

Fair allocation of bandwidth and buffer for traffic control in a high-speed packet network with diverse sources is a critical problem and may involve call admission, flow control, and routing procedures. A resource allocation strategy for call admission and connection at the traffic burst level for high-speed packet networks is presented. The proposed strategy uses a lookup table for allocating the required bandwidth for an arrival call, and measures the actual cell use over the trunk groups to decide subsequent call admission or denial. It results in efficient use of the bandwidth, assuring the desired service quality for connection-oriented services and results in proactive control of network congestion. A model to evaluate an upper bound for the probability of cell loss and to determine the required bandwidth for a desired cell loss rate is developed
