          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.

Ali, et al. Informational [Page 2] 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].
