Abstract RFC 4328 and RFC 7139 provide Resource ReserVation Protocol-Traffic Engineering (RSVP-TE) signaling extensions to control the full set of Optical Transport Network (OTN) features. However, these specifications do not cover the additional Optical channel Data Unit (ODU) containers defined in G.Sup43 (ODU1e, ODU3e1 and ODU3e2). This document defines new signal types for these additional containers. Table of Contents 1. Introduction...................................................2 2.

Introduction [RFC7139] updates the Optical channel Data Unit (ODU)-related portions of [RFC4328] to provide Resource ReserVation Protocol- Traffic Engineering (RSVP-TE) extensions to support control for [G.709-v3] in the OTN-TDM SENDER_TSPEC and OTN-TDM FLOWSPEC objects. However, it does not specify signal types for the containers defined in [G.Sup43] (ODU1e, ODU3e1, and ODU3e2). This document provides RSVP-TE signaling extensions to support these additional signal types. These containers are non-standard data plane frame formats (not defined in ITU-T Recommendations). They are among some of the intra-domain approaches used in networks for transport of 10GBASE-R signals in optical transport networks. As a Supplement, [G.Sup43], does not guarantee interoperability in the data plane for these containers.

RSVP-TE extension for Additional Signal Types [RFC7139] defines the format of Traffic Parameters in OTN-TDM SENDER_TSPEC and OTN-TDM FLOWSPEC objects. These traffic parameters have a signal type field. This document defines the signal type for ODU1e, ODU3e1 and ODU3e2 as defined in the IANA considerations section. They are allocated from the Specification Required policy added to the subregistry by [RFC7892]. 3. Security Considerations This document does not introduce any additional security issues above those identified in [RFC7139]. 4. IANA Considerations IANA maintains a registry called "Generalized Multi-Protocol Label Switching (GMPLS) Signaling Parameters" with a subregistry called "OTN Signal Type". IANA is requested to make three further allocations from this registry under the Specification Required policy for ODU1e, ODU3e1 and ODU3e2 as follows: Value Type ----- ---- TBD (IANA is requested ODU1e (10Gbps Ethernet [G.Sup43]) to assign the value 23) TBD (IANA is requested ODU3e1 (40Gbps Ethernet [G.Sup43]) to assign the value 26) TBD (IANA is requested ODU3e2 (40Gbps Ethernet [G.Sup43]) to assign the value 27) These signaled types are carried in Traffic Parameters in OTN- TDM SENDER_TSPEC and OTN-TDM FLOWSPEC objects [RFC7139]. 5.
