A service composition approach for inter-domain provisioning

Abstract

Inter-domain QoS-aware service provisioning is still a complex task due to the Internet heterogeneity. It is necessary to overcome several obstacles in order to achieve a scenario where providers fully interact to satisfy all customer service requirements. Some of these obstacles are service class specification and service composition. This paper presents an integrated approach for service class specification and service composition that supports the provisioning of QoS-aware services in inter-domain environments. This approach makes use of QoS performance parameters, service-specific parameters and business parameters to compose services that fulfill customer requirements and comply with providers' business expectations.
