QoS is not a new concept, being usually employed in the domain of computer networks to specify a set of parameters typically assigned to transport connections. As a rule, QoS is established through negotiation between service users and providers. The process of negotiation is simple if the resources are managed by a centralized entity (e.g. an operating system) or by a set of homogeneous entities such as a network protocol. Unfortunately, in distributed multimedia applications the negotiation and management of resources is a difficult task since resource are very diversified, dispersed and maintained by heterogeneous entities. To cope with diversity and distribution, an agent-based approach for QoS negotiation and management in open distributed environments is proposed in this paper.  aAgent-based systems  aMobile agents  aQualidade de serviço  aQuality of service  aSistemas multimídia1 aOLIVEIRA, P.
