Cross-layer Quality of Service based admission control for Web services

Web services are in widespread use today. This paper discusses Quality of Service (QoS) concepts which are not covered by existing Web services standards, and focuses on application level solutions that will be important building blocks in the future. We implemented a QoS based admission control mechanism, which provides priority based access to the network, while at the same time avoiding overloading the limited network capacity that is available. We use cross-layer mechanisms to combine QoS mechanisms at the network layer with our Web services admission control broker. The preliminary experiments we have performed with Web services over emulated wireless links are discussed.
