     Abstract
     
     [RFC7139] 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, and ODU3e2). This draft provides GMPLS signaling extension
     for these additional signal types.

     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). With the evolution and deployment
        of Optical Transport Network (OTN) technology, it is necessary
        to support these additional signal types.
     
        This draft provides GMPLS signaling extension to support
        additional signal types mentioned in [G.Sup43] (ODU1e, ODU3e1,
        and ODU3e2). [I-D.draft-ali-ccamp-otn-signal-type-subregistry]
        is a companion document.

     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
        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
     
        [I-D.draft-ali-ccamp-otn-signal-type-subregistry] is a companion
        document where "OTN Signal Type" subregistry to the "Generalized
        Multi-Protocol Label Switching (GMPLS) Signaling Parameters"
        registry has been extended to include Expert Review and private
        ranges.
     
        This document defines signal type for ODU1e, ODU3e1 and ODU3e2
        using ''Expert Review'' range defined in [I-D.draft-ali-ccamp-otn-
        signal-type-subregistry]. Specifically:
                  Value     Type
                  -----     ----
                    230      ODU1e  (10Gbps Ethernet [GSUP.43])
                    231      ODU3e1 (40Gbps Ethernet [GSUP.43])
                    232      ODU3e2 (40Gbps Ethernet [GSUP.43])
     
        These signaled types are carried in Traffic Parameters in OTN-
        TDM SENDER_TSPEC and OTN-TDM FLOWSPEC objects [RFC7139].
