An SLA Re-negotiation ProtocolService Level Agreement (Sla) • October 7th, 2008
Abstract. Service Level Agreements (SLAs) 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 an SLA has been formed it may need to be re- negotiated as the requirements of the SLA participants change. This paper describes an abstract, domain-independent protocol for the re-negotiation of an agreement, including SLAs formed using the WS-Agreement stan- dard. The protocol is based on the principles of contract law to make the new agreements formed using it legally-compliant. It allows for multi- round re-negotiation in a network environment where messages may be lost, delayed, duplicated and re-ordered.
