An SLA Re-Negotiation ProtocolService Level Agreement • October 10th, 2008
Abstract. Service Level Agreements are an essential foundation for the realisation of Business Grids as they provide a mechanism for a service provider to charge a customer for meeting an agreed quality of service. However, once a Service Level Agreement has been formed it may need to be re-negotiated as the requirements of the business participants change. This paper describes an abstract, domain-independent protocol for the re- negotiation of an agreement, including Service Level Agreements formed using the WS-Agreement standard. The protocol is based on the princi- ples of contract law to make the new agreements formed using it legally- compliant. It allows for multi-round re-negotiation in a network environ- ment where messages may be lost, delayed, duplicated and re-ordered.
