Technologies under definition by the IETF Layer 2 VPN
working group and elsewhere such as ATM Forum which include:
·
Virtual Private LAN Service (VPLS)
L2 service that emulates LAN across an IP and an
MPLS-enabled IP network, allowing standard Ethernet devices communicate with
each other as if they were connected to a common LAN segment.
·
Virtual Private Wire Service (VPWS)
L2 service that provides L2 point-to-point
connectivity (e.g. Frame Relay DLCI, ATM VPI/VCI, point-to-point Ethernet)
across an IP and an MPLS-enabled IP network.
·
IP-only L2 VPNs
L2 service across an IP and an MPLS-enabled IP
network, allowing standard IP devices to communicate with each other as if they
were connected to a common LAN segment or a point-to-point circuit.
·
LAN-emulation-over-ATM (LANE)
emulates LAN across an ATM-based network.
