           RSVP-TE Extension for Additional Signal Types in
               G.709 Optical Transport Networks (OTNs)

Abstract

  RFCs 4328 and 7139 provide signaling extensions in Resource
  ReserVation Protocol - Traffic Engineering (RSVP-TE) to control the
  full set of Optical Transport Network (OTN) features.  However, these
  specifications do not cover the additional Optical channel Data Unit
  (ODU) containers defined in G.Sup43 (ODU1e, ODU3e1, and ODU3e2).
  This document defines new Signal Types for these additional
  containers.

RFC 7963       RSVP-TE Ext for Signal Types in G.709 OTNs    August 2016


1.  Introduction

  [RFC7139] updates the portions of text related to the Optical channel
  Data Unit (ODU) described in [RFC4328] to provide extensions to
  Resource ReserVation Protocol - Traffic Engineering (RSVP-TE) to
  support control for [G.709-v3] in the OTN-TDM SENDER_TSPEC and OTN-
  TDM FLOWSPEC objects.  However, it does not specify Signal Types for
  the ODU1e, ODU3e1, and ODU3e2 containers defined in [G.Sup43].  This
  document provides RSVP-TE signaling extensions to support these
  additional Signal Types.

  These containers are non-standard data-plane frame formats (not
  defined in ITU-T Recommendations).  They are among some of the intra-
  domain approaches used in networks to transport 10GBASE-R signals in
  optical transport networks.  As a supplement, [G.Sup43] does not
  guarantee interoperability in the data plane for these containers.

2.  RSVP-TE Extension for Additional Signal Types

  [RFC7139] defines the format of Traffic Parameters in OTN-TDM
  SENDER_TSPEC and OTN-TDM FLOWSPEC objects.  These traffic parameters
  have a Signal Type field.  This document defines the Signal Types for
  ODU1e, ODU3e1, and ODU3e2, as defined in the IANA Considerations
  section.  They are allocated via the Specification Required policy
  added to the subregistry by [RFC7892].

3.  Security Considerations

  This document does not introduce any additional security issues
  beyond those identified in [RFC7139].

4.  IANA Considerations

  IANA maintains the "Generalized Multi-Protocol Label Switching
  (GMPLS) Signaling Parameters" registry that contains the "OTN Signal
  Type" subregistry.  IANA has added the following three allocations
  for ODU1e, ODU3e1, and ODU3e2 in the subregistry via the
  Specification Required policy [RFC5226]:

  Value            Type
  -----            ----
  23               ODU1e  (10Gbps Ethernet [G.Sup43])
  26               ODU3e1 (40Gbps Ethernet [G.Sup43])
  27               ODU3e2 (40Gbps Ethernet [G.Sup43])

  These Signal Types are carried in the Traffic Parameters in OTN-TDM
  SENDER_TSPEC and OTN-TDM FLOWSPEC objects [RFC7139].
