However, these 66 specifications do not cover the additional Optical channel Data 67 Unit (ODU) containers defined in G.Sup43 (ODU1e, ODU3e1 and 68 ODU3e2). This document defines new signal types for these 69 additional containers. 71 Table of Contents 73 1. Introduction...................................................2 74 2.

Introduction 84 [RFC7139] updates the Optical channel Data Unit (ODU)-related 85 portions of [RFC4328] to provide Resource ReserVation Protocol- 86 Traffic Engineering (RSVP-TE) extensions to support control for 87 [G.709-v3] in the OTN-TDM SENDER_TSPEC and OTN-TDM FLOWSPEC 88 objects. However, it does not specify signal types for the 89 containers defined in [G.Sup43] (ODU1e, ODU3e1, and ODU3e2). 90 This document provides RSVP-TE signaling extensions to support 91 these additional signal types. 93 These containers are non-standard data plane frame formats (not 94 defined in ITU-T Recommendations). They are among some of the 95 intra-domain approaches used in networks for transport of 96 10GBASE-R signals in optical transport networks. As a 97 Supplement, [G.Sup43], does not guarantee interoperability in 98 the data plane for these containers. 100 Internet-Draft draft-ietf-ccamp-additional-signal-type-g709v3- 101 04.txt 103 2. RSVP-TE extension for Additional Signal Types 105 [RFC7139] defines the format of Traffic Parameters in OTN-TDM 106 SENDER_TSPEC and OTN-TDM FLOWSPEC objects. These traffic 107 parameters have a signal type field. This document defines the 108 signal type for ODU1e, ODU3e1 and ODU3e2 as defined in the IANA 109 considerations section. They are allocated from the 110 Specification Required policy added to the subregistry by 111 [RFC7892]. 113 3. Security Considerations 115 This document does not introduce any additional security issues 116 above those identified in [RFC7139]. 118 4. IANA Considerations 120 IANA maintains a registry called "Generalized Multi-Protocol 121 Label Switching (GMPLS) Signaling Parameters" with a subregistry 122 called "OTN Signal Type". IANA is requested to make three 123 further allocations from this registry under the Specification 124 Required policy for ODU1e, ODU3e1 and ODU3e2 as follows: 126 Value Type 127 ----- ---- 128 TBD (IANA is requested ODU1e (10Gbps Ethernet [G.Sup43]) 129 to assign the value 23) 130 TBD (IANA is requested ODU3e1 (40Gbps Ethernet [G.Sup43]) 131 to assign the value 26) 132 TBD (IANA is requested ODU3e2 (40Gbps Ethernet [G.Sup43]) 133 to assign the value 27) 135 These signaled types are carried in Traffic Parameters in OTN- 136 TDM SENDER_TSPEC and OTN-TDM FLOWSPEC objects [RFC7139]. 138 5.
