Abstract: A virtual network unit is deployed on an OLT by means of a virtualization technology, and one or more ONUs corresponding to the same contracted service are managed by means of the virtual network unit. The virtual network unit on the OLT can be regarded as a proxy or a gateway for ONUs, and ONUs communicate with a network-side network element by means of the virtual network unit. For the ONUs, the ONUs no longer needs to perform address translation between local area networks and wide area networks, thus simplifying the processing of the ONUs. In addition, the virtual network unit is deployed on the OLT, and the virtual network unit is actually a functional unit of the OLT, so that, according to the method provided in the present application, no passive device needs to be added in PON system architecture, and the advantage that the passive optical network is easy in deployment is thus brought into full play.
