Quality of Service (QoS) Negotiation is a tool for improving the management aspects of Web service-Based architectures. It is the primary means to automatically establish contracts on QoS between service requestors and providers.

In particular, typical issues in loosely coupled environments management, such as service discovery and selection, composition, and monitoring, raise different issues concerned with negotiation of QoS. Finally, QoS negotiation can be implemented according to different paradigms, such as broker-Based architectures and multi-agent systems. Each implementation paradigm introduces specific issues that must be dealt with while tackling the Web service QoS negotiation problem. [CD-IA-1.1.1] {SYN: QoS Negotiation}
