Negotiating service levels - A generic negotiation framework for WS Agreement

Abstract

The Web Services Agreement specification draft proposes a simple request-response protocol for agreement creation only addressing bilateral offer exchanges. Analyzing negotiation taxonomies from the literature clearly proves that as insufficient. This paper proposes a framework that augments the WS-Agreement in order to enable negotiations according to a variety of bilateral and multilateral negotiation protocols in a manner that is compatible with the WS agreement standard.
