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.709/Y.1331 for ODUC1,
ODUC2, ODUC3, ODUC4, ODUC5, ODUC6, ODUC7, ODUC8 and ODUC9. This
document defines new Signal Types for these additional containers.
Conventions used in this document

"SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in
this document are to be interpreted as described in RFC 2119
[RFC2119].

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 beyond 100G ODUCn
containers defined in [G.709/Y.1331]. This document provides
RSVP-TE signaling extensions to support ODUC1, ODUC2, ODUC3,
ODUC4, ODUC5, ODUC6, ODUC7, ODUC8 and ODUC9 Signal Types.

2. RSVP-TE extension for Beyond 100G 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 ODUC1, ODUC2, ODUC3, ODUC4, ODUC5, ODUC6,
ODUC7, ODUC8 and ODUC9, 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.
This document request IANA to add the following signal types in the
subregistry via the Specification Required policy [RFC5226]:
Value Type
----- ----
TBA1 ODUC1 (100Gbps OTN [G.709/Y.1331])
TBA2 ODUC2 (200Gbps OTN [G.709/Y.1331])
TBA3 ODUC3 (300Gbps OTN [G.709/Y.1331])
TBA4 ODUC4 (400Gbps OTN [G.709/Y.1331])
TBA5 ODUC5 (500Gbps OTN [G.709/Y.1331])
TBA6 ODUC6 (600Gbps OTN [G.709/Y.1331])
TBA7 ODUC7 (700Gbps OTN [G.709/Y.1331])
TBA8 ODUC8 (800Gbps OTN [G.709/Y.1331])
TBA9 ODUC9 (900Gbps OTN [G.709/Y.1331])
These Signal Types are carried in the Traffic Parameters in OTN-TDM
SENDER_TSPEC and OTN-TDM FLOWSPEC objects [RFC7139].
