Abstract

The closed-loop rate-based flow control was adopted to support Available Bit Rate (ABR) service in ATM networks, where the transmission rate of each ABR connection is adjusted based on the network feedback information. In this paper, we present an overview of two rate-based control mechanisms : Binary and Explicit Rate. Then, we address the issues of end-to-end traffic management in IP/ATM internetworks, where legacy networks (e.g., Ethernet) are interconnected with ATM networks. We discuss the impact of the ATM flow control mechanisms on the end-to-end performance and implementation requirements at ATM switches and edge devices (e.g., an router interface) in the internetworking environment.
