What is PWE3?
Working group formed for X-over-Packet
- Pseudo-Wire Emulation Edge-to-Edge (PWE3)
- Kick-off meeting in Denver in April 2001
The objective is to support many Layer 1 and Layer 2 services over a common packet switched network infrastructure
- Layer1 & 2 services: Frame Relay, Ethernet, ATM, SONET, TDM…
- PSN: MPLS, IP, L2TP
PWE3 is defining:
- Framework and architecture
- Requirements
- Service-specific protocol drafts that define how each L1 or L2 protocol is encapsulated in PSN frames
- Control protocol to establish connectivity across the PSN
These building blocks can be used by PPVPN
