Abstract. The use of services in large-scale and cross-organizational environments requires the negotiation of agreements that define these services. This paper proposes to specify a negotiation policy for response time of distributed network. The analysis of distributed networks has become more and more important with the evolution of distributed network technologies resulting in increasing capacities. To monitor and manage service in distributed network, we must identify the relationships between network/application performance and QoS parameters. Therefore, we provide a statistical analysis on mapping user level response time to application and network level parameters by using some queueing models and suggest the negotiation of policy specification for response time of distributed network. Hence, the use of guaranteed services becomes feasible.
