Justiça em Modelos de Negociação de Serviços na Internet

Carlos Alberto Kamienski1Djamel SadokAlejandro Frery

As QoS-based services turn into reality in the Internet, the need to develop commercial and technical solutions for providing services that traverse several domains becomes greater. Services with performance guarantees need to be negotiated between domains in an automatic and dynamic way, through efficient, scalable and fair negotiation models. This paper proposes an index for evaluating the level of fairness of how negotiation models distribute resources over domains, as well as a method for performing resource allocation in a fair manner in the hierarchical model. Simulation results showed that this hierarchical model exhibits a fairer behaviour than the other ones, while maintaining a low computational cost.
