摘要：

Firstly, aiming at the uncertainty of link information and users' satisfaction, the relevant knowledge of fuzzy mathematics and probability theory were introduced, and then the method of calculation of the users' QoS evaluation value was proposed. Secondly, the SRLG (shared risk link group)-disjoint and shared-path protection strategies, together with the distinction of the reliability of fault tolerant scheme were used when the single SRLG failure was under consideration. Thirdly, tabu fish swarm intelligent optimization algorithm was used to find the route, and finally a tabu fish swarm preventive fault-tolerant QoS unicast routing mechanism was proposed. The proposed mechanism was used to find the working path and the protective path which were satisfied the QoS constraint conditions and also could guarantee the end-to-end reliability, optimize link-cost and QoS evaluation value of the route. Simulation results showed that the proposed mechanism was feasible and effective. ©, 2014, Northeastern University. All right reserved.
