+            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].
