The first ONU is any one of the ONUs, and as an example, the ONUs may be m ONUs (m < n) among n ONUs, and m may be determined according to an actual situation, which is not limited herein, and as an example, m may be 4. n ONUs may be denoted as ONU 1. The first ONU may be any one of ONU1, ONUm, and for convenience of understanding, the first ONU is referred to as an ONU 1.

The first request may be a communication request, and as an example, the communication request may be a dialing request, such as a request for normal end-to-end service application. The end-to-end service is provided by an end-to-end data flow between the ONUx and the server, which may be denoted as end-to-end data flow 1 for ease of understanding. The virtual management entity responds to a first request of the first ONU; establishing a networking table among the ONUs based on the first request may be to include the ONUs into a networking table based on the first request; as an example, it may be understood that the virtual management entity responds to the first request, and binds a plurality of ONUs in a scene where the first ONU is located, where the binding may be understood as a networking relationship, that is, a networking relationship exists among the ONUs; and establishing a networking table among the plurality of ONUs according to the networking relation. The scene can be a certain user family in the FTTR; for ease of understanding, a certain user home may be denoted as user home 1.

To better understand, here an application scenario is illustrated, the first request may be a dial request, which the user normally applies for from a certain ONU1 of the FTTR scenario (end-to-end service). The Virtual ONUx on the OLT responds to the request, binds ONU1 to ONUm in the user home 1 where ONU1 is located, and records forwarding information such as necessary dialing information and Virtual Local Area Network (VLAN).
