* SDN based Slice manager desgin and analysis for End-to End QoS Service
The service requirements of the next-generation mobile communication network include low latency, high capacity, massive connection, and high reliability, and various radio, access, and core network technologies have been proposed to support this. In particular, the next-generation mobile communication network needs a network slicing function that can flexibly handle various network resources and satisfy quality of service (Qos) end-to-end to reflect future service requirements. SDN (software-defined networking)-based slice manager architecture design that can guarantee end-to-end service quality to service providers is required.

* MP-TCP
This research aims to improve transmission performance by reducing network throughput, reliable transmission, and transmission delay by using multiple transmission paths. For this purpose, transmission path management, packet transmission scheduling, subflow management, and congestion control in mutipath are handled. Performance analysis in a real network environments are performed for the evaluation of the MP-TCP.
