WS-Agreement is an OGF proposal for a language and protocol to agree on service usage details. The WS-Agreement protocol is based on a single round "offer, accept" message exchange. More sophisticated negotiation protocols can be established using auctions or contract net from multi-agent systems. | ||||

Service Level
Agreement (SLA) Negotiation is a process carried out between Service Providers and Requesters by
formulating, exchanging and evaluating a number of SLA proposals that
may end with the stipulation of a contract in the form of an SLA.
