Abstract

Per-VC scheduling and credit-based flow control were studied separately in the past. This paper presents the performance evaluation of joint per-VC scheduling and credit-based flow control in a three-node high-speed ATM wide area network. The traffic types used in the study are a combination of delay-sensitive (DS), delay-insensitive (DI) and best effort (BE) qualities of service. At the network level the ATM switches perform credit-based flow control for DI and BE traffic and peak rate allocation for DS traffic. At the node level a per-connection scheduling algorithm is used to determine the eligibility of a connection to transmit cells during a given slot. In this paper we simulate the behavior of the above mentioned network in order to evaluate ifs performance
