ICT service composition method based on service catalogue model

With the wider utilization of information technology, the requirement for ICT services becomes more diverse and differentiated. In order to manage ICT services and meet requirements of customers effectively, an ICT service catalogue model is structured, which can make service providers and customers obtain accurate and consistent service information. On the service catalogue, a new service composition method is proposed and composed of following two steps: service selection based on service functions and service composition based on service levels. The feasibility of the method is evaluated and verified by simulation experiments.
