英文摘要： Fiber and wireless access network convergence is one of hotpots in the research and development of the next generation access network. The project, using the basic priciples of network virtualization, focuses on the convergence of heterogeneous access network, resource sharing networking model,method and key technologies. In order to establish the foundation of access network resources' global control and unified scheduling, the hierarchical model and the service model of network virtualization based fiber and wireless access network are investigated, using hierarchical model to hide the diversity of fiber and wireless access network and the differences of heterogeneous network's physical techologies, migrating services upon virtual network. Resource-awared multipath routing mechanism is also investigated, to meet the diversity of users' service needs in fiber and wireless access network and the differences of fiber network resources and wireless network resources. The key node in fiber and wireless access network and experiment systems are developed, building the testbed based on software-defined network (SDN) that supports innovative networking and new emerged service experiment.
