Generalized MPLS (GMPLS) Support for Metro Ethernet Forum
and G.8011 User Network Interface (UNI)
Abstract
This document describes a method for controlling two specific types
of Ethernet switching via a GMPLS-based User Network Interface (UNI).
This document supports the types of switching required by the
Ethernet services that have been defined in the context of the Metro
Ethernet Forum (MEF) and International Telecommunication Union (ITU)
G.8011. This document is the UNI companion to "Generalized MPLS
(GMPLS) Support for Metro Ethernet Forum and G.8011 Ethernet Service
Switching". This document does not define or limit the underlying
intra-domain or Internal NNI (I-NNI) technology used to support the
UNI.

RFC 6005 GMPLS Support for MEF and G.8011 UNI October 2010
1. Introduction
[MEF6] and [G.8011] provide parallel frameworks for defining network-
oriented characteristics of Ethernet services in transport networks.
The framework discusses general Ethernet connection characteristics,
Ethernet User Network Interfaces (UNIs), and Ethernet Network-Network
Interfaces (NNIs). Within this framework, [G.8011.1] defines the
Ethernet Private Line (EPL) service and [G.8011.2] defines the
Ethernet Virtual Private Line (EVPL) service. [MEF6] covers both
service types. [MEF10.1] defines service parameters and [MEF11]
provides UNI requirements and framework.
This document provides a method for GMPLS-based control of Label
Switched Paths (LSPs) that support the transport services defined in
the above documents at the UNI network reference points. This
document does not define or limit the underlying intra-domain or
Internal NNI (I-NNI) technology used to support the UNI. This
