     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].
