Robust rate control for ABR sources

The paper considers the design of explicit rate-based flow control for available bit rate (ABR) sources in an ATM network. The goal is to share the available capacity "fairly" among many sources while maintaining queue length at a bottleneck node at a desired level. This problem is formulated as a stochastic control problem, and in this framework rate-control mechanisms are developed, which stabilize the queue length even though different sources may have different round-trip delays to the bottleneck node. Various robustness properties of the solution are illustrated through simulation experiments.
