C4 VPWS Overview

VPWS makes integration of existing Layer 2 and Layer 3 services possible on a point-to-point basis across a service provider's IP/MPLS network. Implementation examples include Any Transport over MPLS (AToM) and L2TPv3. Both AToM and L2TPv3 support the transport of Frame Relay, ATM, High-Level Data Link Control (HDLC), and Ethernet traffic over an IP/MPLS core.
