Managing real-time web services through agents

Abstract

Time is an important Quality of Service (QoS) parameter in services. In many situations, the response provided by a service could be completely useless if it is not provided on time. In this paper the infrastructure to provide a real-time web service (RTWS) is described. These RTWS are provided by agents with the capability of negotiation and guaranteeing the service execution time. These kind of agents control the service execution time and allow a provider-client negotiation process in order to arrive at an agreement on when the service response is it to be provided. If an agreement is reached, these agents also guarantee that the agreement is going to be fulfilled. Finally, tests to validate RTWSs and the behavior of provider agents are presented.
