QoS multicast routing optimization based on clonal selection

Influence of QoS multicast routing is the larger delay,bandwidth,at the expense of performance indicators,this paper presents an optimization algorithm for multiple constrained QoS multicast routing based on genetic algorithm.Introduce a comprehensive performance index of Q fitness function,to weigh in on time delay,bandwidth,at the expense of the three performance indicators.The cost of delay is small,the multicast tree bandwidth,improve the multicast service quality.And effective solution to the traditional algorithm for the existence of two group and multicast tree above,their price is the best,do not choose to delay and bandwidth can satisfy the constrained conditions of the problem.
