Model of Software Defined Network Service-flow Control to QoE-driven

WANG Li;Nanjing University of Posts and Telecommunications;  
In this paper,study the optimization of service- flow control based on software defined network,through Quality of Experience( Qo E)- driven,introducing a Qo S matching and optimization models,adopting the negotiation of service and network communication parameters betw een end- users,assign the network paths that are used for delivering multimedia flow s according to the agreed service configuration. Based on the concept of software defined networks,the logical control functions and high- level policy of the network can be dynamically managed and configured flexibly by the central controller,in order to achieve a centralized multi- user optimization of the path assignments. Therefore,propose a new service- flow control model that allow s delivering multimedia service- flow over the best available path using the best service configuration,in order to achieve the goal of maximizing the overall Qo E.
