TAPAS - Trusted and QoS-Aware Provision of Application Services

The overall objective of the TAPAS project is to develop novel methods, tools, algorithms and protocols that support the construction and provisioning of Internet application services. The project will achieve the overall objective by developing QoS enabled middleware services capable of meeting Service Level Agreements (SLAs) between application services and will enhance component based middleware technologies such that components can be deployed and interact across organisational boundaries. The project will develop notations for expressing SLAs to enable specification of QoS, such as the availability as well as trust relationships. SLA trust specifications will be used for deriving service invocation primitives enriched with authentication, non-repudiation mechanisms, with or without the involvement of trusted third parties.
