SDN/NFV OPEN ACCESS NETWORK SYSTEM, AND METHOD AND DEVICE FOR MANAGING ONU

摘要

An SDN/NFV open access network system, comprising a virtual optical line terminal (vOLT), an access network device with an Openflow switching capability, and an ONU, wherein the vOLT and the access network device are interconnected by means of an Openflow switching network; the access network device and the ONU are interconnected by means of an optical distribution network (ODN). Also disclosed is a method for an SDN/NFV open access network system to manage an ONU. By combining an OVS network of the SDN and the conventional ONU management, the primary ODN network architecture can be fully used, and the management process of configuring, maintaining, and updating the ONU is simplified.
