An implementation of a service class providing assured TCP rates within the AQUILA framework

Christof Brandauer, Peter Dorfinger (2003): An implementation of a service class providing assured TCP rates within the AQUILA framework In: Proceedings of the Workshop on Architectures for Quality of Service in the Internet (Art-QoS), pages 203-217, March 2003

This paper investigates an attempt to establish a QoS class that supports long-lived, bulk-data TCP flows that require a minimum rate from the network. The approach is based on a model for TCP flows
subject to token bucket marking at the network edge and preferential
dropping in the core network. The service class adds admission control
functionality and a model for multi-RED queue management to the token
bucket marker. The difficulty of parameterizing the mechanisms is
discussed and analyzed in an explorative simulation study. A set of configuration parameters that enables a successful operation of the service class is identified and the achievable service provisioning is shown.
