Abstract

For 5G millimeter wave network, low latency and high reliable network are necessary. Based on SDN/NFV, we explored network and computation aspects of 5G millimeter-wave network that support on-demand slicing and flexible networking.

We established a 5G millimeter wave network system suitable for vertical industry applications specifically for high speed mobile experience. We design our own topology for high speed application among access network, bearer network, core network and other network facilities. We deployed a new network resource management and distribution system based on SDN and NFV, and it focuses on the logical network slicing that synchronizes forwarding and computation of the link layer data. Our application of the flexible ad hoc network achieves the flexible movement of the network element function, the flexible reconstruction of the network element service, and the flexible changes of the network element connection. Furthermore, we researched a network dynamic switching mechanism that monitors base stations in real time, tracks link sessions, and guarantees service quality.

SDN and NFV are essential to achieve low latency and high reliable network for the millimeter wave 5G network. We adopt new SDN switch with two aspects: synchronization of communication and computing, and forwarding on link layer. The SDN switch implements an efficient and dynamic switching network from two aspects, switching point selection and quality of service guarantee. By applying this new SDN switch on the special railway ring test line, we tested wireless dynamical network in multiple scenarios with low latency and high reliability. The network is composed by millimeter wave links as an application access network, fiber as a core network, SDN switching equipment, and integrated technologies of SDN and NFV. We achieved an average of 2.2G for upstream and downstream bandwidth, 135 microseconds switching latency, packet delay of less than 1 millisecond, end-to-end delay of less than 1 millisecond, and packet loss rate of less than 0.01%.
