Characterization and semantic modeling of services in multiservice networks

Abstract

The use of the Internet as a global communication infrastructure to support a wide range of multiconstrained applications and services poses new challenges to ISPs regarding network services management and auditing. In this context, the semantic characterization and modeling of services provided to users assumes an essential role in fostering service management automation. Moreover, the semantic and formal description of services allows enhancing the negotiation and interoperability between clients and service providers. This paper reports the first steps toward the definition of an ontology for multiservice networks that eases and systemizes decision support of QoS deployment in ISP infrastructures, according to service levels established in SLAs. Other management tasks such as dynamic service negotiation and configuration, service monitoring and auditing may also benefit from the present ontology proposal.
