RSVP-TE Extension for Additional Signal Types in G.709 Optical Transport Networks (OTNs)
G.709光传输网络（OTN）中附加信号类型的RSVP-TE扩展
Abstract
摘要
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.
RFCs 4328和7139在资源预留协议-流量工程（RSVP-TE）中提供信令扩展，以控制全套光传输网络（OTN）功能。但是，这些规范不包括G.Sup43（ODU1e、ODU3e1和ODU3e2）中定义的附加光信道数据单元（ODU）容器。本文件为这些附加容器定义了新的信号类型。

[RFC7139] updates the portions of text related to the Optical channel Data Unit (ODU) described in [RFC4328] to provide extensions to Resource ReserVation Protocol - Traffic Engineering (RSVP-TE) 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 ODU1e, ODU3e1, and ODU3e2 containers defined in [G.Sup43]. This document provides RSVP-TE signaling extensions to support these additional Signal Types.
[RFC7139]更新了[RFC4328]中描述的与光信道数据单元（ODU）相关的文本部分，以提供对资源预留协议-流量工程（RSVP-TE）的扩展，以支持对OTN-TDM发送方和OTN-TDM FLOWSPEC对象中[G.709-v3]的控制。但是，它没有为[G.Sup43]中定义的ODU1e、ODU3e1和ODU3e2容器指定信号类型。本文档提供RSVP-TE信令扩展，以支持这些额外的信号类型。
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, [G.Sup43] does not guarantee interoperability in the data plane for these containers.
这些容器是非标准数据平面帧格式（未在ITU-T建议中定义）。它们是网络中用于在光传输网络中传输10GBASE-R信号的一些域内方法之一。作为补充，[G.Sup43]不保证这些容器在数据平面中的互操作性。
[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 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 [RFC7892].
[RFC7139]定义OTN-TDM SENDER_TSPEC和OTN-TDM FLOWSPEC对象中流量参数的格式。这些交通参数有一个信号类型字段。本文件定义了IANA注意事项部分中定义的ODU1e、ODU3e1和ODU3e2的信号类型。它们通过[RFC7892]添加到子地区的规范要求策略进行分配。
This document does not introduce any additional security issues beyond those identified in [RFC7139].
除[RFC7139]中确定的安全问题外，本文件不引入任何其他安全问题。
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 [RFC5226]:
IANA维护“通用多协议标签交换（GMPLS）信令参数”注册表，该注册表包含“OTN信号类型”子区。IANA已通过规范要求策略[RFC5226]为分区中的ODU1e、ODU3e1和ODU3e2添加了以下三种分配：
Value Type
----- ----
23 ODU1e (10Gbps Ethernet [G.Sup43])
26 ODU3e1 (40Gbps Ethernet [G.Sup43])
27 ODU3e2 (40Gbps Ethernet [G.Sup43])
Value Type
----- ----
23 ODU1e (10Gbps Ethernet [G.Sup43])
26 ODU3e1 (40Gbps Ethernet [G.Sup43])
27 ODU3e2 (40Gbps Ethernet [G.Sup43])
These Signal Types are carried in the Traffic Parameters in OTN-TDM SENDER_TSPEC and OTN-TDM FLOWSPEC objects [RFC7139].
这些信号类型在OTN-TDM SENDER_TSPEC和OTN-TDM FLOWSPEC对象[RFC7139]中的流量参数中携带。
