     [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, ODU3e2) or (ODU1f, ODU2f). 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, ODU3e2) or (ODU1f and ODU2f). 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,
        ODU3e2) for the experimental purpose and ODU1f and ODU2f for the
        private use.

     Internet-Draft draft-ali-ccamp-additional-signal-type-g709v3-03.txt
        [I-D.draft-ali-ccamp-otn-signal-type-subregistry] is a companion
     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, ODU3e2, ODU1f and ODU2f 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 experimental and private
        This document defines signal type for ODU1e, ODU3e1 and ODU3e2
        using ''experimental'' range defined in [I-D.draft-ali-ccamp-otn-
        signal-type-subregistry]. This document also defines signal type
        for ODU1f and ODU2f using ''private use'' range defined in [I-
        D.draft-ali-ccamp-otn-signal-type-subregistry]. Specifically:
                  Value     Type
                  -----     ----
                    200      ODU1e  (10Gbps Ethernet [GSUP.43])
                    201      ODU3e1 (40Gbps Ethernet [GSUP.43])
                    202      ODU3e2 (40Gbps Ethernet [GSUP.43])
                    220      ODU1f
                    221      ODU2f
        These signaled types are carried in Traffic Parameters in OTN-
        TDM SENDER_TSPEC and OTN-TDM FLOWSPEC objects [RFC7139].
