Martini draft
Encyclopedia
The Martini drafts are contributions made to the IETF's PWE3 (Pseudo Wire Emulation Edge-to-Edge) working group by Luca Martini of Cisco Systems
(formerly of Level 3 Communications
) and a number of other authors. They define a method to transport a layer 2 protocol across an MPLS
network.
The "Martini-trans" draft defines the transport mechanism using the LDP
protocol.
The "Martini-encaps" series of drafts defines how specific layer 2 protocols are encapsulated prior to being carried in the MPLS network. Provision is made for SONET/SDH
, Ethernet
, ATM
and frame relay
.
The encapsulation defined by the "Martini-drafts" has been published as a "Historical" RFC -- RFC 4905 -- Encapsulation Methods for Transport of Layer 2 Frames over MPLS Networks.

Multiprotocol Label Switching
Multiprotocol Label Switching is a mechanism in high-performance telecommunications networks that directs data from one network node to the next based on short path labels rather than long network addresses, avoiding complex lookups in a routing table. The labels identify virtual links between...
