Auto-negotiated service level agreements in service negotiation protocols with guaranteed quality of services

摘要

This paper deals with the auto-negotiation problem in service negotiation protocols (SrNP) where service level agreements (SLA) with guaranteed quality of services (QoS) are made. At first, a constrained resource allocation problem is formulated to allocate the available resources provided by the service provider to satisfy customers' requirements. If the service provider can satisfy customer's requirements, contracting between both parties is then followed. Otherwise, for the case where there is no solution to meet customers' requirements, the customer can change their requirements and negotiate with service provider again three times before seeking for the alternatives. A mental model is developed for a customer to adjust the profile of the requirements for the second- or third-round of negotiation. A penalty model is used to protect customers from failing to achieve the contracted customers' requirements in the service provider.
