New media identity authentication and traffic optimization in 5G network

New media has increased communication between people all over the world and the Internet. Problems can be solved by centralized management of SDN controller in 5G, such as security and limited bandwidth in new media. An authentication server and a database server are connecting to the same switch. SDN controller generates a flow table routing to the authentication server, when it receives requirements of accessing media content. With successful authentication, it optimizes network traffic. According to data type, a multiple route calculation method is proposed by modifying Dijkstra algorithm. The method provides reliable transmit routes for higher quality of service (QoS). To test the proposed strategies, prototype system was designed with an ODL controller and switches. And the system implements the authentication and hierarchical transmit functions.
