An Application-Driven-based Network Resource Control Method

With the expansion of the scale of Internet users and the increasing of network application types, the motive force of the network development has gradually changed from technologies to applications, and the network resources need be customized for different applications in order to guarantee different QoS. However, network resources are always scarce for application requirements, and the existing works only attach importance to guarantee QoS of network applications and ignore the promotion of the network resources utilization. So, an Application-Driven-based Network Resource Control Method (ADNRC) is presented in this paper. The thought of the separation of the transmission and the control based on SDN is introduced in this method, and the network slices for different applications are constructed to customize the network resources and guarantee QoS of network applications. At the same time, the multi-path routes between the sources and the destinations are generated during the procedure of constructing the network slices, and the network flows are scheduled in real time based on the multi-path routes and the network status to enhance the utilization of network resources. The experimental results show that the proposed method in this paper is better than existing methods in the aspect of both the QoS guarantee of network applications and the promotion of the network resources utilization.
