 A YANG model to manage the optical interface parameters for an external transponder in a WDM network
 
 draft-ietf-ccamp-dwdm-if-param-yang-11.txt
 Date: 05/07/2024
 Authors: Gabriele Galimberti, Dharini Hiremagalur, Gert Grammel, Roberto Manzotti, Dirk Breuer
 Working Group: Common Control and Measurement Plane (ccamp)
 This memo defines a Yang model related to the Optical Transceiver parameters characterising coherent 100G and above interfaces. 100G and above Transceivers support coherent modulation, multiple modulation formats, multiple FEC codes including some not yet specified (or in phase of specification by) ITU-T G.698.2 or any other ITU-T recommendation. Use cases are described in RFC7698. Is to be noted that the Transceivers can be located on the Transponders (optical layer) or on the Router (in general packet layer) in form of Pluggable modules. The Yang model defined in this memo can be used for Optical Parameters monitoring and/or configuration of the endpoints of a multi-vendor IaDI optical link. The use of this model does not guarantee interworking of transceivers over a DWDM. Optical path feasibility and interoperability has to be determined by tools and algorithms outside the scope of this document. The purpose of this model is to program interface parameters to consistently configure the mode of operation of transceivers.
 A YANG Data Model for Optical Impairment-aware Topology
 
 draft-ietf-ccamp-optical-impairment-topology-yang-17.txt
 Date: 21/10/2024
 Authors: Dieter Beller, Esther Le Rouzic, Sergio Belotti, Gabriele Galimberti, Italo Busi
 Working Group: Common Control and Measurement Plane (ccamp)
 In order to provision an optical connection through optical networks, a combination of path continuity, resource availability, and impairment constraints must be met to determine viable and optimal paths through the network. The determination of appropriate paths is known as Impairment-Aware Routing and Wavelength Assignment (IA-RWA) for WSON, while it is known as Impairment-Aware Routing and Spectrum Assignment (IA-RSA) for SSON. This document provides a YANG data model for the impairment-aware TE topology in optical networks.
 A YANG Data Model for Transport Network Client Signals
 
 draft-ietf-ccamp-client-signal-yang-13.txt
 Date: 01/08/2024
 Authors: Haomian Zheng, Aihua Guo, Italo Busi, Anton Snitser, Chaode Yu
 Working Group: Common Control and Measurement Plane (ccamp)
 A transport network is a server-layer network to provide connectivity services to its client. The topology and tunnel information in the transport layer has already been defined by generic Traffic- engineered models and technology-specific models (e.g., OTN, WSON). However, how the client signals are accessing to the network has not been described. These information is necessary to both client and provider. This draft describes how the client signals are carried over transport network and defines YANG data models which are required during configuration procedure. More specifically, several client signal (of transport network) models including ETH, STM-n, FC and so on, are defined in this draft.
 Common YANG Data Types for Layer 1 Networks
 
 draft-ietf-ccamp-layer1-types-18.txt
 Date: 23/02/2024
 Authors: Haomian Zheng, Italo Busi
 Working Group: Common Control and Measurement Plane (ccamp)
 This document defines a collection of common common data types, identities, and groupings in the YANG data modeling language. These derived common common data types, identities, and groupings are intended to be imported by modules that model Layer 1 configuration and state capabilities. The Layer 1 types are representative of Layer 1 client signals applicable to transport networks, such as Optical Transport Networks (OTN). The Optical Transport Network (OTN) data structures are included in this document as Layer 1 types.
 A YANG Data Model for Ethernet TE Topology
 
 draft-ietf-ccamp-eth-client-te-topo-yang-07.txt
 Date: 14/10/2024
 Authors: Chaode Yu, Haomian Zheng, Aihua Guo, Italo Busi, Yunbin Xu, Yang Zhao, Xufeng Liu
 Working Group: Common Control and Measurement Plane (ccamp)
 This document describes a YANG data model for Ethernet networks when used either as a client-layer network of an underlay transport network (e.g., an Optical Transport Network (OTN)) or as a transport network itself.
 Framework and Data Model for OTN Network Slicing
 
 draft-ietf-ccamp-yang-otn-slicing-07.txt
 Date: 07/07/2024
 Authors: Aihua Guo, Luis Contreras, Sergio Belotti, Reza Rokui, Yunbin Xu, Yang Zhao, Xufeng Liu
 Working Group: Common Control and Measurement Plane (ccamp)
 The requirement of slicing network resources with desired quality of service is emerging at every network technology, including the Optical Transport Networks (OTN). As a part of the transport network, OTN can provide hard pipes with guaranteed data isolation and deterministic low latency, which are highly demanded in the Service Level Agreement (SLA). This document describes a framework for OTN network slicing and defines YANG data models with OTN technology-specific augments deployed at both the north and south bound of the OTN network slice controller. Additional YANG data model augmentations will be defined in a future version of this draft.
 Common YANG Data Types for Layer 0 Networks
 
 draft-ietf-ccamp-rfc9093-bis-12.txt
 Date: 04/12/2024
 Authors: Sergio Belotti, Italo Busi, Dieter Beller, Esther Le Rouzic, Aihua Guo
 Working Group: Common Control and Measurement Plane (ccamp)
 This document defines a collection of common data types, identities, and groupings in the YANG data modeling language. These common types and groupings, derived from the built-in YANG data types, identities, and groupings are intended to be imported by modules that model Layer 0 configuration and state capabilities, such as Wavelength Switched Optical Networks (WSONs) and flexi-grid Dense Wavelength Division Multiplexing (DWDM) networks. This document obsoletes RFC 9093 by replacing the YANG module it contained with a new revision that includes additional YANG data types, identities and groupings.
 YANG Data Model for FlexE Management
 
 draft-ietf-ccamp-flexe-yang-cm-05.txt
 Date: 25/11/2024
 Authors: Minxue Wang, Liuyan Han, Xuesong Geng, Jin Zhou, Luis Contreras, Xufeng Liu
 Working Group: Common Control and Measurement Plane (ccamp)

 Use cases,Network Scenarios and gap analysis for Packet Optical Integration (POI) with coherent plugables under ACTN Framework
 
 draft-ietf-ccamp-actn-poi-pluggable-usecases-gaps-00.txt
 Date: 21/10/2024
 Authors: Oscar de Dios, Jean-Francois Bouquier, Julien Meuric, Gyan Mishra, Gabriele Galimberti
 Working Group: Common Control and Measurement Plane (ccamp)
 This document provides general overarching guidelines for control and management of packet over optical converged networks with coherent pluggables and focuses on operators' use cases and network scenarios. It provides a set of use cases which are needed for the control and management of the packet over optical networks which comprise devices with mixes of packet and optical functions where the optical functions may be provided on coherent pluggables. The document provides a gap analysis to solve the use cases.
 Integrating YANG Configuration and Management into an Abstraction and Control of TE Networks (ACTN) System for Optical Networks
 
 draft-ietf-ccamp-actn-optical-transport-mgmt-02.txt
 Date: 28/11/2024
 Authors: 谭艳霞, XingZhao, Chaode Yu, Daniel King, Adrian Farrel
 Working Group: Common Control and Measurement Plane (ccamp)
 Many network technologies are operated as Traffic Engineered (TE) networks. Optical networks are a particular case, and have complex technology-specific details. Abstraction and Control of TE Networks (ACTN) is a management architecture that abstracts TE network resources to provide a limited network view for customers to request and self-manage connectivity services. It also provides functional components to orchestrate and operate the network. Management of legacy optical networks is often provided via Fault, Configuration, Accounting, Performance, and Security (known as FCAPS) using mechanisms such as the Multi-Technology Operations System Interface (MTOSI) and the Common Object Request Broker Architecture (CORBA). FCAPS can form a critical part of configuration management and service assurance for network operations. However, the ACTN architecture as described in RFC 8453 does not include consideration of FCAPS. This document enhances the ACTN architecture as applied to optical networks by introducing support for FCAPS. It considers which elements of existing IETF YANG work can be used to solve existing scenarios and emerging technologies, and what new work may be needed. In doing so, this document adds rich-detail network management to the ACTN architecture. This enhanced architecture may then be used to evolve networks from CORBA and MTOSI FCAPS interfaces to IETF-based YANG and RESTful APIs.

Charter for Working Group

The CCAMP working group is responsible for standardizing a common
control plane and a separate common measurement plane for non-packet
technologies found in the Internet and in the networks of telecom
service providers (ISPs and SPs). Examples of the devices in such
networks include photonic cross-connects, OEO switches, ROADMs, TDM
switches, microwave links, and Ethernet switches.

In this context, measurement refers to the acquisition and
distribution of attributes relevant to the setting up of tunnels
and paths.

The working group develops extensions to core Traffic Engineering
protocols that are under the care of other working groups. The CCAMP
working group will coordinate with the TEAS working group to ensure
that extensions that can be generalized for use with more than one
technology are made appropriately, and with the working groups that
have responsibility for the specific protocols.

CCAMP WG work scope includes:

  • Definition of protocol-independent metrics and parameters
    (measurement attributes) for describing links and paths that are
    required for routing and signaling in technology-specific
    networks. These will be developed in conjunction with requests
    and requirements from other WGs to ensure overall usefulness.

  • Maintenance and extension of the Link Management Protocol (LMP).

  • Functional specification of extensions for GMPLS-related routing
    (OSPF, ISIS) and signaling (RSVP-TE) protocols required for path
    establishment and maintenance in non-packet, technology-specific
    networks. Protocol formats and procedures that embody these
    extensions will be done jointly with the WGs supervising those
    protocols and the TEAS working group has the responsibility to
    determine whether such protocol extensions should be generalized
    for Traffic Engineering in any network.

This may include protocol work to support data planes that have
already been approved by another Standards Development
Organization. Note that the specification or modification of data
planes is out of scope of this working group

  • Definition of management objects (e.g., as part of MIB modules
    or YANG models) and control of OAM techniques relevant to the
    protocols and extensions specified within the WG. The OAM work
    will be synchronized with the LIME WG

  • Describe non-packet-specific aspects of traffic engineering
    including for multi-areas/multi-AS/multi-layer scenarios and
    define protocol extensions in cooperation with the TEAS and
    PCE working groups.

  • Define how the properties of network resources gathered by a
    measurement protocol (or by other means such as configuration)
    can be distributed in existing routing protocols, such as OSPF,
    IS-IS, and BGP-LS. CCAMP will work with the WGs that supervise
    these

The CCAMP WG currently works on the following tasks:

  • Protocol extensions in support of WSON.

  • Protocol extensions in support of flexible grid lambda networks.

  • Maintenance of existing protocol extensions for non-packet
    technology-specific networks (Ethernet, TDM, OTN) already
    specified by CCAMP.

  • Maintenance of LMP.
