RFC 6003               Ethernet Traffic Parameters          October 2010

1.  Introduction

   Per [RFC3471], Generalized Multi-Protocol Label Switching (GMPLS)
   allows the inclusion of technology-specific parameters in signaling.
   This document introduces Ethernet SENDER_TSPEC and FLOWSPEC-specific
   objects in support of Metro Ethernet Forum (MEF) Ethernet traffic
   parameters as specified in [MEF10.1] and ITU-T Ethernet Service
   Switching as discussed in [RFC6004].  For example:

   o  For Ethernet Private Line (EPL) services [MEF6], these traffic
      parameters are applicable to each Ethernet Virtual Connection
      (EVC) crossing a given port.

   o  For Ethernet Virtual Private Line (EVPL) services [MEF6], these
      traffic parameters are applicable per Ethernet Virtual Connection
      (EVC) with a single or multiple Class of Service (CoS),
      independent of its associated Virtual LAN ID (VID) or set of VIDs.

      Association between EVC and VIDs is detailed in [MEF10.1].  The
      format and encoding of the VID (or set of VIDs) is documented in a
      companion document [RFC6004].

   This does not preclude broader usage of the Ethernet SENDER_TSPEC and
   FLOWSPEC-specific objects specified this document.  For instance,
   they may also be used for signaling Ethernet Label Switched Paths
   (LSPs), in the Generalized Label Request (see [RFC3471]), the
   Switching Type field is set to Layer 2 Switching Capability (L2SC)
   and the LSP Encoding Type field to Ethernet.

2.  Conventions Used in This Document

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].

   Moreover, the reader is assumed to be familiar with the terminology
   in [MEF10.1] as well as in [RFC3471] and [RFC3473].

3.  Overview

   In GMPLS RSVP-TE [RFC3473], the SENDER_TSPEC object is used on a Path
   message to indicate the bandwidth that is requested for the LSP being
   established, and the FLOWSPEC object is used on a Resv message to
   indicate the bandwidth actually reserved for the LSP.  The Ethernet
   SENDER_TSPEC/FLOWSPEC object includes the Ethernet link type
   (switching granularity) of the requested LSP and the MTU value for

   the LSP.  Other information about the requested bandwidth
   characteristics of the LSP are carried in the Bandwidth Profile as a
   TLV within the Ethernet SENDER_TSPEC/FLOWSPEC object.

   The Ethernet SENDER_TSPEC/FLOWSPEC object includes the Ethernet link
