<span class="h1">RSVP-TE Extension for Additional Signal Types in</span>
<span class="h1">G.709 Optical Transport Networks (OTNs)</span>
Abstract
RFCs 4328 and 7139 provide signaling extensions in Resource
ReserVation Protocol - Traffic Engineering (RSVP-TE) 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.

<span class="h2"><a class="selflink" id="section-1" href="#section-1">1</a>. Introduction</span>
[<a id="ref-RFC7139">RFC7139</a>] updates the portions of text related to the Optical channel
Data Unit (ODU) described in [<a href="./rfc4328" title=""Generalized Multi-Protocol Label Switching (GMPLS) Signaling Extensions for G.709 Optical Transport Networks Control"">RFC4328</a>] to provide extensions to
Resource ReserVation Protocol - Traffic Engineering (RSVP-TE) to
support control for [<a href="#ref-G.709-v3" title=""Interfaces for the optical transport network"">G.709-v3</a>] in the OTN-TDM SENDER_TSPEC and OTN-
TDM FLOWSPEC objects. However, it does not specify Signal Types for
the ODU1e, ODU3e1, and ODU3e2 containers defined in [<a href="#ref-G.Sup43" title=""Transport of IEEE 10GBASE-R in optical transport networks (OTN)"">G.Sup43</a>]. 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 to transport 10GBASE-R signals in
optical transport networks. As a supplement, [<a href="#ref-G.Sup43" title=""Transport of IEEE 10GBASE-R in optical transport networks (OTN)"">G.Sup43</a>] does not
guarantee interoperability in the data plane for these containers.
<span class="h2"><a class="selflink" id="section-2" href="#section-2">2</a>. RSVP-TE Extension for Additional Signal Types</span>
[<a id="ref-RFC7139">RFC7139</a>] 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 Types for
ODU1e, ODU3e1, and ODU3e2, as defined in the IANA Considerations
section. They are allocated via the Specification Required policy
added to the subregistry by [<a href="./rfc7892" title=""IANA Allocation Procedures for the GMPLS OTN Signal Type Registry"">RFC7892</a>].
<span class="h2"><a class="selflink" id="section-3" href="#section-3">3</a>. Security Considerations</span>
This document does not introduce any additional security issues
beyond those identified in [<a href="./rfc7139" title=""GMPLS Signaling Extensions for Control of Evolving G.709 Optical Transport Networks"">RFC7139</a>].
<span class="h2"><a class="selflink" id="section-4" href="#section-4">4</a>. IANA Considerations</span>
IANA maintains the "Generalized Multi-Protocol Label Switching
(GMPLS) Signaling Parameters" registry that contains the "OTN Signal
Type" subregistry. IANA has added the following three allocations
for ODU1e, ODU3e1, and ODU3e2 in the subregistry via the
Specification Required policy [<a href="./rfc5226" title="">RFC5226</a>]:
Value Type
----- ----
23 ODU1e (10Gbps Ethernet [<a href="#ref-G.Sup43" title=""Transport of IEEE 10GBASE-R in optical transport networks (OTN)"">G.Sup43</a>])
26 ODU3e1 (40Gbps Ethernet [<a href="#ref-G.Sup43" title=""Transport of IEEE 10GBASE-R in optical transport networks (OTN)"">G.Sup43</a>])
27 ODU3e2 (40Gbps Ethernet [<a href="#ref-G.Sup43" title=""Transport of IEEE 10GBASE-R in optical transport networks (OTN)"">G.Sup43</a>])
These Signal Types are carried in the Traffic Parameters in OTN-TDM
SENDER_TSPEC and OTN-TDM FLOWSPEC objects [<a href="./rfc7139" title=""GMPLS Signaling Extensions for Control of Evolving G.709 Optical Transport Networks"">RFC7139</a>].
