Traffic control in high-speed ATM networks

This paper presents a framework of traffic control in high-speed ATM networks on both connection level and cell level. On the connection level, we consider traffic classification, bandwidth allocation, call admission control, and billing method. On the cell level we examine a queueing architecture, flow control, and scheduling. We also capture the interdependencies among various traffic control aspects to ensure a proper network operation. The key contribution of this paper is an integrated methodology to handle bursty data traffic. Based on the per-VC queueing architecture, we introduce (1) a simple bandwidth allocation mechanism which requires no complex computation for call admission control, (2) an improved credit-based flow control scheme which ensures lossless and congestion-free cell transport, (3) an innovative scheduling algorithm with throughput guarantee, and (4) an easy billing method which imposes tariff on bursty data flows without real-time measurement and processing.
