Performance evaluation of connectionless service for ATM networks

This paper investigates the performance of the direct approach to connectionless service over ATM. The direct approach utilizes connectionless servers, attached to or incorporated in a subset of the ATM switches, to provide a packet switching service. The number of connectionless servers and ATM connections utilized by the direct approach is found analytically and compared to alternative approaches. Furthermore, the effects of two architectural options that significantly impact the performance of connectionless servers, the packet forwarding scheme (packet-based and cell-based) and the flow control scheme (static rate control and a dynamic proportional rate control) are also evaluated
