Focus on the scenario that service composition took place to provide stream media service,presented a novel ser-vice routing algorithm.It took delay,bandwidth,package loss rate and service access ability as its metrics,and transfered multiple constraints to linear constraints,and then be resolved using linear programming.The simulation results show that it not only solves the problem of quality of service,but also keeps the load balancing among service instances.
