Research on QoS-assured Service Routing Algorithm in Distributed Service Network
Service composition can make up new services by combining some services in the network.For the problem of service path selection in service composition,a QoS-assured service routing algorithm in distributed service network is proposed.The content includes a function F which aggregates multiple QoS constraints by calculating the length of vector and a bottle-neck selection algorithm BNS.BNS sorts the services sequence by bottle-neck and make special filtration to minish the search graph and improve the search efficiency.The simulation shows that the algorithm can achieve good success ratio and balance of service network.
