Abstract: |
In order to meet the users performance demand and service quality guarantee,according to the characteristics of complex network service composition and the users personalized quality of service(QoS) demand,the network aware service composition in cloud environment is studied.By utilizing the QoS attribute of cloud service and network service,a network aware service composition algorithm based on optimal path selection(OPS) is proposed,which can improve network service quality and user experience quality.The simulation results show that the algorithm has good performance in both solving time and quality,can dynamically adapt to the complex needs of users,and can effectively solve the problem of service composition in cloud computing environment. |
