     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].
