A Semantic Based Framework for Supporting Negotiation in Service Oriented Architectures
Found in: E-Commerce Technology, IEEE International Conference on
By Marco Comuzzi, Kyriakos Kritikos, Pierluigi Plebani
Issue Date:July 2009
pp. 137-145
Negotiation is required before invoking a service in order to identify how the invocation must occur in terms of functional and non-functional criteria. This process is possible when all the involved parties agree on the same negotiation protocol (e.g., bi...
Establishing and Monitoring SLAs in Complex Service Based Systems
Found in: Web Services, IEEE International Conference on
By Marco Comuzzi, Constantinos Kotsokalis, George Spanoudakis, Ramin Yahyapour
Issue Date:July 2009
pp. 783-790
In modern service economies, service provisioning needs to be regulated by complex SLA hierarchies among providers of heterogeneous services, defined at the business, software, and infrastructure layers. Starting from the SLA Management framework defined i...
A Framework for Hierarchical and Recursive Monitoring of Service Based Systems
Found in: Internet and Web Applications and Services, International Conference on
