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, ODU3e2) or (ODU1f, ODU2f). This draft provides GMPLS signaling extension for these additional signal types. Conventions used in this document The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT", "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this document are to be interpreted as described in RFC 2119 [RFC2119].

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. Expires January 2015 [Page 2] Internet-Draft draft-ali-ccamp-additional-signal-type-g709v3-03.txt [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, 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 ranges. 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]. 5.
