GMPLS Routing Extension for Optical Transport Networks with Beyond 100G
in G.709 Edition 5
draft-fan-ccamp-gmpls-g709v5-ospf-ext-00.txt
Abstract
The International Telecommunication Union Telecommunication
Standardization Sector (ITU-T) has extended the Recommendation G.709
to support beyond 100G (B100G) features. Corresponding Open Shortest
Path First - Traffic Engineering (OSPF-TE) routing protocol
extensions are included in this document.

1. Introduction
G.709 [G.709-2016] defines the interfaces to Optical Transport
Network (OTN) and includes new features to support beyond 100G
(B100G). In order to advertise this information in routing, this
document extends the encoding specific to OTN technology for use in
GMPLS OSPF-TE as defined in [RFC7138].
Routing information for Optical Channel (OCh) layer is beyond the
scope of this document. Please refer to [RFC6163] and [RFC6566] for
further information.
2. Terminology
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 [RFC2119].

3. OSPF-TE Extensions for B100G
As discussed in [GMPLSv5-fwk], OSPF-TE must be extended to be able
to advertise the 5G Tributary Slot Granularity, the multiplexing
capabilities of ODUCn connection requests, and the support
information of OTUCn sub rates (OTUCn-M).
