Pseudo-Wire Emulation Edge to Edge (PWE3) is an end-to-end technology used to bear Layer 2 services, and belongs to the Layer 2 virtual private network (L2VPN) in the point-to-point mode. PWE3 adopts the Label Distribution Protocol (LDP) as the signaling mode, emulates Layer 2 services such as Layer 2 data packets on the Customer Edge (CE) through tunnels such as Multi-protocol Label Switch Protocol Label Switched Paths (MPLS LSPs), and transparently transmits the Layer 2 data of the CE in the PSN network. This emulation is proximate but not absolute. For example, this proximate emulation may cause distortion for the Time Division Multiplexing (TDM) data.
The related draft of PWE3 provides the public MIB. The draft is constantly updated and is not completely consistent with the PWE3 implementation of the device, so the private MIB is defined for the PWE3 module. The task of this module is to implement the functions defined by the private MIB on the managed devices. The PWE3 MIB contains the public MIB.
