Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Layer 2 Tunneling Protocol Version 3 is an IETF standard that related to L2TP that can be used as an alternative protocol to Multiprotocol Label Switching (MPLS) for encapsulation of multiprotocol Layer 2 communications traffic over IP networks. Like L2TP, L2TPv3 provides a 'pseudo-wire' service, but scaled to fit carrier requirements. L2TPv3 can be regarded as being to MPLS what IP is to ATM: a simplified version of the same concept, with much of the goodness achieved with a fraction of the effort, at the cost of losing some technical features considered less important in the market. In the case of L2TPv3, the features lost are teletraffic engineering features considered important in MPLS.
