L2TPv3

Layer 2 Tunneling Protocol Version 3 is a draft version of L2TP that is proposed as an alternative protocol to MPLS for encapsulation of multiprotocol Layer 2 communications traffic over Internet Protocol networks. Like L2TP, L2TPv3 provides a ‘pseudo-wire’ service, but scaled to fit carrier requirements.

L2TPv3 can be regarded as being to MPLS what MPLS is to of L2TPv3 is also significantly bigger than MPLS. However, there is no reason why these features could not be re-engineered in or on top of L2TPv3 in later products.
