Abstract
[I-D.draft-ietf-ccamp-gmpls-signaling-g709v3] provides the
extensions to the Generalized Multi-Protocol Label Switching
(GMPLS) signaling to control the full set of OTN features including
ODU0, ODU4, ODU2e and ODUflex. However, it does not cover
additional signal types mentioned in [G.Sup43] (ODU1e, ODU3e1,
ODU3e2) or (ODU1f, ODU2f). This draft provides GMPLS signaling
extension for these additional signal types.

1. Introduction
[I-D.draft-ietf-ccamp-gmpls-signaling-g709v3] updates the ODU-
related portions of [RFC4328] to provide Resource ReserVation
Protocol-Traffic Engineering (RSVP-TE) extensions to support
control for [G.709-v3]. However, it does not cover additional
signal types mentioned in [G.Sup43] (ODU1e, ODU3e1, ODU3e2) or
(ODU1f and ODU2f).
With the evolution and deployment of Optical Transport Network
(OTN) technology, it is necessary to support additional signal
types mentioned in [G.Sup43] and (ODU1f and ODU2f). [I-D.draft-
khuzema-ccamp-gmpls-signaling-g709] had support for signal types
mentioned in [G.Sup43] but the signal types values collides with
values defined in [I-D.draft-ietf-ccamp-gmpls-signaling-g709v3].
The draft has expired and also does not support ODU1f and ODU2f
signal type.

Internet-Draft draft-ali-ccamp-additional-signal-type-g709v3-01.txt
This draft provides GMPLS signaling extension to support
additional signal types mentioned in [G.Sup43] and (ODU1f and
ODU2f).
2. RSVP-TE extension for Additional Signal Types
[I-D.draft-ietf-ccamp-gmpls-signaling-g709v3] defines the format
of Traffic Parameters in OTN-TDM SENDER_TSPEC and OTN-TDM
FLOWSPEC objects. The said traffic parameters have a signal type
field. This document defines the signal type for ODU1e, ODU3e1,
ODU3e2, ODU1f and ODU2f, as follows:
Value Type
----- ----
23 ODU1e (10Gbps Ethernet [GSUP.43])
24 ODU1f (10Gbps Fiber Channel)
25 ODU2f (10Gbps Fiber Channel)
26 ODU3e1 (40Gbps Ethernet [GSUP.43])
27 ODU3e2 (40Gbps Ethernet [GSUP.43])
3. Security Considerations
This document does not introduce any additional security issues
above those identified in [I-D.draft-ietf-ccamp-gmpls-signaling-
g709v3].
4. IANA Considerations
This document defines signal type for ODU1e, ODU3e1, ODU3e2,
ODU1f and ODU2f to be carried in Traffic Parameters in OTN-TDM
SENDER_TSPEC and OTN-TDM FLOWSPEC objects [I-D. draft-ietf-
ccamp-gmpls-signaling-g709v3].
