UNI/NNI

UNI/NNI

A UNI refers to the Ethernet port that is connected to the user equipment. A UNI is used for the user-side configuration of an Ethernet service. An NNI refers to the Ethernet port that is connected to the packet transport network. An NNI is used for the network-side configuration of an Ethernet service.

UNI

  • V-UNI

    A V-UNI is a virtual user-network interface. Each service on a UNI corresponds to a logical V-UNI, which is the Ethernet virtual interface that is created on the NMS based on the network plan.

    A UNI can receive multiple services. That is, a UNI may correspond to multiple V-UNIs.

NNI

Based on the modes of carrying services, NNIs can be classified into two types, namely, NNIs carrying services by PWs, and NNIs carrying services by QinQ links.

  • Ethernet Services Carried by PWs

    For NNIs that carry Ethernet services by PWs, you need to create static MPLS tunnels for the NNIs. To create Ethernet services carried by PWs, you need to create the PWs first. In this case, different Ethernet services can be encapsulated into different PWs and transmitted in a tunnel to the same NNI. Therefore, the occupied NNIs are reduced and the bandwidth utilization is improved.
