Abstract

[RFC4328]

RFC 4328 and [RFC7139] RFC 7139 provide the extensions to Generalized
Multi-Protocol Label Switching (GMPLS) Resource ReserVation Protocol-Traffic
Engineering (RSVP-TE) signaling extensions to control the full set
of OTN features including ODU0, ODU1, ODU2, ODU3, ODU4,
ODU2e and ODUflex. Optical Transport Network (OTN) features. However, these
specifications do not cover the additional signal types ODU1e, ODU3e1, and ODU3e2 mentioned Optical channel Data
Unit (ODU) containers defined in
[G.Sup43]. G.Sup43 (ODU1e, ODU3e1 and
ODU3e2). This draft provides GMPLS signaling extensions document updates RFC 7139 to define new signal types
for these additional signal types.

1. Introduction

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

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 type for ODU1e, ODU3e1 and ODU3e2 as defined in the IANA
considerations section. They are allocated from the
Specification Required policy added to the subregistry by
[draft-subreg].

03.txt

3. Security Considerations

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

4. IANA Considerations

This document defines signal type

IANA maintains a registry called "Generalized Multi-Protocol
Label Switching (GMPLS) Signaling Parameters" with a subregistry
called "OTN Signal Type". IANA is requested to make three
further allocations from this registry under the Specification
Required policy for ODU1e, ODU3e1 and ODU3e2, ODU3e2 as follows:

Value Type
----- ----
TBD (IANA is requested ODU1e (10Gbps Ethernet [GSUP.43]) [G.Sup43])
to assign the value 23)
TBD (IANA is requested ODU3e1 (40Gbps Ethernet [GSUP.43]) [G.Sup43])
to assign the value 26)
TBD (IANA is requested ODU3e2 (40Gbps Ethernet [GSUP.43]) [G.Sup43])
to assign the value 27)

These signaled types are carried in Traffic Parameters in OTN-
TDM SENDER_TSPEC and OTN-TDM FLOWSPEC objects [RFC7139].
