QoS adaptation is an important process in inter-domain service mana g ement, since it can g uarantee the correct service provisionin g when unexpected events occur.However, in inter-domain environments, the human interference and the manual-based operations hamper the deployment of expeditious mechanisms to adapt the QoS of the services. This paper presents an approach based on SOA principles to perform QoS adaptation in these environments. This approach allows providers to determine the new QoS parameters, rene g otiate these parameters with other providers alon g the provisionin g path, update their contracts and enforce the chan g es in the equipment confi g uration in an automatic and on-demand fashion. The QoS adaptation process can be caused by technical (QoS violations, infrastructure malfunctions) or business (financial problems)issues. In addition, if a provider confi g uration in the provisionin g path already supports the new requirements, this provider is not affected by the adaptation, thus decreasin g the processin g time.

“…At the end, the algorithm selects the rightmost node since it has the greater value, and consequently the most appropriate QoS criteria composition. Figure 1 presents the QoS model for business layers integrated in the GBF architecture [6], which was inspired by the IPsphere framework [11]. This architecture is used to support providers in offering and managing inter-domain QoSaware services for customers.…”

“…Instead, it aims to find a feasible path that can satisfy both the customer service requirements and the providers' business expectations by using the QoS performance parameters, the service-specific parameters and the business parameters of each service element. To evaluate our service composition approach, experimental tests were undertaken in the prototype developed in the context of the GBF [6] and the QoS model [5]. This prototype was implemented in Java.…”

“…This solution was deployed in the context of a QoS model for business layers and the Global Business Framework (GBF), which were already presented in [5] and [6], respectively. The GBF architecture supports providers in offering and managing inter-domain services by publishing, dynamically searching and combining service parts (service elements) through a Business Layer (BL).…”

A service composition approach for inter-domain provisioning

2010 International Conference on Network and Service Management

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.
