Abstract

In view of the complex network information and the increasing coding delay arising from large amounts of Gate and Report message exchanges in the Network Coding（NC）control process of the conventional hybrid Fiber-Wireless（FiWi）access networks

we design an NC-supported software-defined FiWi network architecture and an openflow-based NC control scheme.The simulation results show that the proposed centralized control method and its implementation scheme in the software-defined FiWi network architecture can reduce the amount of the controlled information

improve the bandwidth utilization rate

effectively reduce the data transmission delay and improve the network throughput.
