Design, Implementation and Evaluation of a QoS-Aware Transport Protocol

Overview In the context of a reconfigurable transport protocol framework, the paper proposes a QoS-aware Transport Protocol (QSTP), specifically designed to operate over QoS-enabled networks with bandwidth guarantee. QSTP combines QoS-aware TFRC congestion control mechanism, which takes into account the network-level bandwidth reservations, with a Selective ACKnowledgment (SACK) mechanism in order to provide a QoS-aware transport service that fill the gap between QoS enabled network services and QoS constraint applications. The paper has developed a prototype of this protocol in the user-space and conducted a large range of measurements to evaluate this proposal under various network conditions.
