Integrating WS-Agreement with a framework for service-oriented infrastructures

Abstract

Service level agreements are an intrinsic part of service level management frameworks. They are electronic contracts, or part of a contract, and capture quality-of-service guarantees, responsibilities and constraints related to the provision and consumption of services. In the area of distributed systems a handful of service level agreement specifications exist, designed to support the automated management of service-related agreements. Each of these specifications has a different focus and targets a different group of usage scenarios and stakeholders. In this paper, we show, based on the example of the WS-Agreement specification, how to make use of SLA@SOI's service level agreement model SLA* to map between different service level agreement representations and thus be able to integrate a variety of different specifications into one service-oriented infrastructure.
