Connection Admission Control for Hard Real-Time Communication in ATM Networks

Connection Admission Control (CAC) is needed in ATM networks to provide Quality of Service (QoS) guarantees to real-time connections. This paper presents a CAC scheme based on a bit-stream traffic model, which is capable of modeling traffic generation patterns of CBR/VBR connections and traffic distortions within a network, and worst-case queueing analysis to obtain cell queueing delay bounds. The proposed CAC scheme can be used to establish hard real-time connections in ATM networks with conventional static priority FIFO queueing switches. The effectiveness of the scheme is illustrated by applying it to RTnet, an ATM-based real-time plant control network currently being developed by the Mitsubishi Electric Corporation. The CAC scheme presented in the paper can also be extended to set up soft real-time connections in ATM networks.
