Service Composition Quality Evaluation in SPICE Platform
The goal of the SPICE project is to develop an extendable overlay architecture and framework to support easy and quick creation, and deployment of Telecommunication and Information Services. The SPICE Service Creation Environment (SCE) is used by developers to create both basic services and complex service compositions, which are then deployed in the SPICE Service Execution Environment (SEE), which hide the complexity of the communication environment. Along with its functional interface, each service exposes its own nonfunctional properties (like Response Time, Cost, Availability, etc...) by means of the SPATEL service description language. These properties are defined in an ontology and this chapter will discuss how the SCE helps developers in evaluating a service composition by calculating the aggregated values of such properties.
