Constraint-Based Policy Negotiation and Enforcement for Telco Services
Telco services are evolving under several aspects: for instance, services may combine different telecommunication features (messaging, multi-media, etc.) and may be activated and controlled by applications deployed in a3rd party domain. Telco infrastructures are following this trend by adopting Service Oriented Architecture solutions, e.g. for composing services and for introducing uniform interaction models among services. In a SOA-based system, capabilities, requirements and general features of services can be expressed in terms of policies. Such policies are negotiated in order to define a Service Level Agreement among the involved parties. In this paper we show how to specify, negotiate, and enforce policies for Telco services by using a constraint-based model, the cc-pi calculus. This language extends concurrent constraint programming with synchronous communication and local names, and with the notion of soft constraints, that generalise classical constraints to represent prefe...
