This paper presents a proposal for predict failures in OBS grid network to assist applications in collaborative environments, like E-Science. Agents (DQMA-Fuzzy) monitoring traffic for QoS parameters related and others related to imperfections in optical links. By presenting a solution faster and easily implementable, a system based on fuzzy logic has been developed to give more robustness and flexibility in decisionmaking agents. NS-2 (Network Simulator – 2) simulations show that the proposed Fuzzy-DQMA is able to minimize blockages and balancing the use of grid resources, ensuring well-defined service levels, assisting in traffic engineering and fault prediction. Keywords— optical network, OBS, GMPS, Fuzzy Logic.
