The emergence of service providers and brokers who are independent of network providers has opened the way to a spot market in free network resources: it is under everybody's eyes that market enabled service provision based on Service Level Agreements (SLAs) will be essential for the delivery of many services such as bandwidth on demand. In order for those services to be created, configured and delivered dynamically via automated SLAs, a market enabling mechanism is required that is sufficiently flexible to convey the varying information requirements of the various stakeholders involved in the service delivery chain, together with their internal processes. In this paper an innovative framework for the negotiation of services with quality assurances is presented. The study is conducted keeping an eye on the latest standard proposals coming from the electronic business research community, with respect to both the modeling methodology and the actual design for implementation.
