Towards a novel framework for handling multi-level SLA in cross-organizational enterprise collaboration
Abstract
SLA (Service Level Agreement) is a contract between a service consumer and a service provider. It aims at specifying conditions of services delivery and guarantees to ensure required quality of service (QoS). Nowadays, to satisfy complex client needs, inter-enterprises collaboration must take place to provide new value added services and form inter-organizational extended enterprises. In this context, SLAs composition primitives are needed to define complex dependencies and agreements between services composition. In this paper, we are interested in the problem of SLAs composition where consumer-to-provider and provider-to-provider relationships can hold in cross-organizational enterprise. The aim is to define a framework to assist business decision makers to automatically generate and manage a composition of SLAs to fulfill end-to-end functional and non functional requirements.
