     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). 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).  

        With the evolution and deployment of Optical Transport Network 
        (OTN) technology, it is necessary to support additional signal 
        types mentioned in [G.Sup43]. [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.

     Internet-Draft draft-ali-ccamp-additional-signal-type-g709v3-02.txt 
      
        This draft provides GMPLS signaling extension to support 
        additional signal types mentioned in [G.Sup43]. 

     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, as defined in the IANA consideration section.  

         
     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 and ODU3e2 
        to be carried in Traffic Parameters in OTN-TDM SENDER_TSPEC and 
        OTN-TDM FLOWSPEC objects [I-D. draft-ietf-ccamp-gmpls-signaling-
        g709v3]. This document defines the signal type for ODU1e, 
        ODU3e1, ODU3e2, as defined in the following:  

                  Value     Type 
                  -----     ---- 
                    23      ODU1e  (10Gbps Ethernet [GSUP.43]) 
                    24      ODU3e1 (40Gbps Ethernet [GSUP.43]) 
                    25      ODU3e2 (40Gbps Ethernet [GSUP.43]) 
                    0xD0-0xF0 (208-240)   
                            A range assigned under the "Private Use" 
                            policy described in [RFC2434]. 
         

        The range assigned under the "Private Use" policy described in 
        [RFC2434] for values intended for private use by one party or 
        among mutually consenting parties. Values in this range extend 
        from 10,000 to 99,999.  IANA will not make any allocations from 
        this range.
