Abstract
[RFC4328] and [RFC7139] provide the extensions to the Generalized
Multi-Protocol Label Switching (GMPLS) signaling to control the
full set of OTN features including ODU0, ODU1, ODU2, ODU3, ODU4,
ODU2e and ODUflex. However, these specifications do not cover
additional signal types ODU1e, ODU3e1, and ODU3e2 mentioned in
[G.Sup43]. This draft provides GMPLS signaling extension for these
additional signal types.

this document are to be interpreted as described in RFC 2119
[RFC2119].

1. Introduction
[RFC7139] 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, and ODU3e2). This draft provides GMPLS signaling
extension 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. The said traffic
parameters have a signal type field. This document defines the

Internet-Draft draft-ali-ccamp-additional-signal-type-g709v3-05.txt
signal type for ODU1e, ODU3e1 and ODU3e2 as defined in the IANA
consideration section.
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 for ODU1e, ODU3e1 and ODU3e2,
as follows:
Value Type
----- ----
TBD ODU1e (10Gbps Ethernet [GSUP.43])
TBD ODU3e1 (40Gbps Ethernet [GSUP.43])
TBD ODU3e2 (40Gbps Ethernet [GSUP.43])
These signaled types are carried in Traffic Parameters in OTN-
TDM SENDER_TSPEC and OTN-TDM FLOWSPEC objects [RFC7139].
