+ + + + + + CCAMP Working Group + + + + + +This document defines a collection of common data types and groupings + in the YANG data modeling language. These derived common types and + groupings are intended to be imported by modules that model Layer 0 + optical Traffic Engineering (TE) 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. + + + + + + + + + + + + +
Introduction + +YANG is a data modeling language used to model + configuration data, state data, Remote Procedure Calls, and + notifications for network management protocols such as the Network + Configuration Protocol (NETCONF) . The YANG language + supports a small set of built-in data types and provides mechanisms + to derive other types from the built-in types. + +This document introduces a collection of common data types derived + from the built-in YANG data types. The derived types and groupings + are designed to be the common types applicable for modeling Traffic + Engineering (TE) features as well as non-TE features (e.g., physical + network configuration aspects) for Layer 0 optical networks in + model(s) defined outside of this document. The applicability of + Layer 0 types specified in this document includes Wavelength Switched + Optical Networks (WSONs) and , and flexi-grid Dense + Wavelength Division Multiplexing (DWDM) networks + . + +This document adds new type definitions to the YANG modules and + obsoletes . For further details, see the revision + statements of the YANG module in or the summary in + . + +The YANG data model in this document conforms to the Network + Management Datastore Architecture defined in . + +

Security Considerations + +The YANG module specified in this document defines a schema for data + that is designed to be accessed via network management protocols such + as NETCONF or RESTCONF . The lowest NETCONF layer + is the secure transport layer, and the mandatory-to-implement secure + transport is Secure Shell (SSH) . The lowest RESTCONF layer + is HTTPS, and the mandatory-to-implement secure transport is TLS + . + +The Network Configuration Access Control Model (NACM) + provides the means to restrict access for particular NETCONF or + RESTCONF users to a preconfigured subset of all available NETCONF or + RESTCONF protocol operations and content. The NETCONF protocol over + Secure Shell (SSH) specification describes a method for + invoking and running NETCONF within a Secure Shell (SSH) session as + an SSH subsystem. + +The objects in this YANG module are common data types and groupings. + No object in this module can be read or written to. These + definitions can be imported and used by other Layer 0 specific + modules.

+ + + + + + + + + + + + Amplified multichannel dense wavelength division multiplexing applications with single channel optical interfaces + + ITU-T Recommendation G.698.2 + + + + + + + + + + The YANG 1.1 Data Modeling Language + + + + YANG is a data modeling language used to model configuration data, state data, Remote Procedure Calls, and notifications for network management protocols. This document describes the syntax and semantics of version 1.1 of the YANG language. YANG version 1.1 is a maintenance release of the YANG language, addressing ambiguities and defects in the original specification. There are a small number of backward incompatibilities from YANG version 1. This document also specifies the YANG mappings to the Network Configuration Protocol (NETCONF). + + + + + + + + + Network Configuration Protocol (NETCONF) + + + + + + + The Network Configuration Protocol (NETCONF) defined in this document provides mechanisms to install, manipulate, and delete the configuration of network devices. It uses an Extensible Markup Language (XML)-based data encoding for the configuration data as well as the protocol messages. The NETCONF protocol operations are realized as remote procedure calls (RPCs). This document obsoletes RFC 4741. [STANDARDS-TRACK] + + + + + + + + + Network Management Datastore Architecture (NMDA) + + + + + + + + Datastores are a fundamental concept binding the data models written in the YANG data modeling language to network management protocols such as the Network Configuration Protocol (NETCONF) and RESTCONF. This document defines an architectural framework for datastores based on the experience gained with the initial simpler model, addressing requirements that were not well supported in the initial model. This document updates RFC 7950. + + + + + + + + + Key words for use in RFCs to Indicate Requirement Levels + + + + In many standards track documents several words are used to signify the requirements in the specification. These words are often capitalized. This document defines these words as they should be interpreted in IETF documents. This document specifies an Internet Best Current Practices for the Internet Community, and requests discussion and suggestions for improvements. + + + + + + + + + + Ambiguity of Uppercase vs Lowercase in RFC 2119 Key Words + + + + RFC 2119 specifies common key words that may be used in protocol specifications. This document aims to reduce the ambiguity by clarifying that only UPPERCASE usage of the key words have the defined special meanings. + + + + + + + + + + Generalized Labels for Lambda-Switch-Capable (LSC) Label Switching Routers + + + + + Technology in the optical domain is constantly evolving, and, as a consequence, new equipment providing lambda switching capability has been developed and is currently being deployed. + Generalized MPLS (GMPLS) is a family of protocols that can be used to operate networks built from a range of technologies including wavelength (or lambda) switching. For this purpose, GMPLS defined a wavelength label as only having significance between two neighbors. Global wavelength semantics are not considered. + In order to facilitate interoperability in a network composed of next generation lambda-switch-capable equipment, this document defines a standard lambda label format that is compliant with the Dense Wavelength Division Multiplexing (DWDM) and Coarse Wavelength Division Multiplexing (CWDM) grids defined by the International Telecommunication Union Telecommunication Standardization Sector. The label format defined in this document can be used in GMPLS signaling and routing protocols. [STANDARDS-TRACK] + + + + + + + + + Generalized Labels for the Flexi-Grid in Lambda Switch Capable (LSC) Label Switching Routers + + + + + + + GMPLS supports the description of optical switching by identifying entries in fixed lists of switchable wavelengths (called grids) through the encoding of lambda labels. Work within the ITU-T Study Group 15 has defined a finer-granularity grid, and the facility to flexibly select different widths of spectrum from the grid. This document defines a new GMPLS lambda label format to support this flexi-grid. + This document updates RFCs 3471 and 6205 by introducing a new label format. + + + + + + + + + YANG Data Model for Traffic Engineering (TE) Topologies + + + + + + + + + This document defines a YANG data model for representing, retrieving, and manipulating Traffic Engineering (TE) Topologies. The model serves as a base model that other technology-specific TE topology models can augment. + + + + + + + + + OSPF Extensions in Support of Generalized Multi-Protocol Label Switching (GMPLS) + + + + + This document specifies encoding of extensions to the OSPF routing protocol in support of Generalized Multi-Protocol Label Switching (GMPLS). [STANDARDS-TRACK] + + + + + + + + + + Common YANG Data Types for Traffic Engineering + + Huawei + + + Futurewei Technologies + + + Alef Edge + + + Cisco Systems Inc. + + + Individual + + + + This document defines a collection of common data types and groupings + in YANG data modeling language. These derived common types and + groupings are intended to be imported by modules that model Traffic + Engineering (TE) configuration and state capabilities. This document + obsoletes RFC 8776. + + + + + + + + + + + GMPLS OSPF-TE Extensions in Support of Flexi-Grid Dense Wavelength Division Multiplexing (DWDM) Networks + + + + + + + + The International Telecommunication Union Telecommunication standardization sector (ITU-T) has extended its Recommendations G.694.1 and G.872 to include a new Dense Wavelength Division Multiplexing (DWDM) grid by defining channel spacings, a set of nominal central frequencies, and the concept of the "frequency slot". Corresponding techniques for data-plane connections are known as "flexi-grid". + Based on the characteristics of flexi-grid defined in G.694.1 and in RFCs 7698 and 7699, this document describes the Open Shortest Path First - Traffic Engineering (OSPF-TE) extensions in support of GMPLS control of networks that include devices that use the new flexible optical grid. + + + + + + + + + RESTCONF Protocol + + + + + + This document describes an HTTP-based protocol that provides a programmatic interface for accessing data defined in YANG, using the datastore concepts defined in the Network Configuration Protocol (NETCONF). + + + + + + + + + Using the NETCONF Protocol over Secure Shell (SSH) + + + + This document describes a method for invoking and running the Network Configuration Protocol (NETCONF) within a Secure Shell (SSH) session as an SSH subsystem. This document obsoletes RFC 4742. [STANDARDS-TRACK] + + + + + + + + + The Transport Layer Security (TLS) Protocol Version 1.3 + + + + This document specifies version 1.3 of the Transport Layer Security (TLS) protocol. TLS allows client/server applications to communicate over the Internet in a way that is designed to prevent eavesdropping, tampering, and message forgery. + This document updates RFCs 5705 and 6066, and obsoletes RFCs 5077, 5246, and 6961. This document also specifies new requirements for TLS 1.2 implementations. + + + + + + + + + Network Configuration Access Control Model + + + + + The standardization of network configuration interfaces for use with the Network Configuration Protocol (NETCONF) or the RESTCONF protocol requires a structured and secure operating environment that promotes human usability and multi-vendor interoperability. There is a need for standard mechanisms to restrict NETCONF or RESTCONF protocol access for particular users to a preconfigured subset of all available NETCONF or RESTCONF protocol operations and content. This document defines such an access control model. + This document obsoletes RFC 6536. + + + + + + + + + + + + + + + + + Spectral grids for WDM applications: DWDM frequency grid + + ITU-T Recommendation G.694.1 + + + + + + + + Spectral grids for WDM applications: CWDM wavelength grid + + ITU-T Recommendation G.694.2 + + + + + + + + + + Framework for GMPLS and Path Computation Element (PCE) Control of Wavelength Switched Optical Networks (WSONs) + + + + + + This document provides a framework for applying Generalized Multi-Protocol Label Switching (GMPLS) and the Path Computation Element (PCE) architecture to the control of Wavelength Switched Optical Networks (WSONs). In particular, it examines Routing and Wavelength Assignment (RWA) of optical paths. + This document focuses on topological elements and path selection constraints that are common across different WSON environments; as such, it does not address optical impairments in any depth. This document is not an Internet Standards Track specification; it is published for informational purposes. + + + + + + + + + Framework and Requirements for GMPLS-Based Control of Flexi-Grid Dense Wavelength Division Multiplexing (DWDM) Networks + + + + + + + + + To allow efficient allocation of optical spectral bandwidth for systems that have high bit-rates, the International Telecommunication Union Telecommunication Standardization Sector (ITU-T) has extended its Recommendations G.694.1 and G.872 to include a new Dense Wavelength Division Multiplexing (DWDM) grid by defining a set of nominal central frequencies, channel spacings, and the concept of the "frequency slot". In such an environment, a data-plane connection is switched based on allocated, variable-sized frequency ranges within the optical spectrum, creating what is known as a flexible grid (flexi-grid). + Given the specific characteristics of flexi-grid optical networks and their associated technology, this document defines a framework and the associated control-plane requirements for the application of the existing GMPLS architecture and control-plane protocols to the control of flexi-grid DWDM networks. The actual extensions to the GMPLS protocols will be defined in companion documents. + + + + + + + + + A YANG Data Model for Layer 0 Types + + + + + + + + This document defines a collection of common data types and groupings in the YANG data modeling language. These derived common types and groupings are intended to be imported by modules that model Layer 0 optical Traffic Engineering (TE) configuration and state capabilities such as Wavelength Switched Optical Networks (WSONs) and flexi-grid Dense Wavelength Division Multiplexing (DWDM) networks. + + + + + + + + + Routing and Wavelength Assignment Information Model for Wavelength Switched Optical Networks + + + + + + + This document provides a model of information needed by the Routing and Wavelength Assignment (RWA) process in Wavelength Switched Optical Networks (WSONs). The purpose of the information described in this model is to facilitate constrained optical path computation in WSONs. This model takes into account compatibility constraints between WSON signal attributes and network elements but does not include constraints due to optical impairments. Aspects of this information that may be of use to other technologies utilizing a GMPLS control plane are discussed. + + + + + + + + + Routing and Wavelength Assignment Information Encoding for Wavelength Switched Optical Networks + + + + + + + + A Wavelength Switched Optical Network (WSON) requires certain key information fields be made available to facilitate path computation and the establishment of Label Switched Paths (LSPs). The information model described in "Routing and Wavelength Assignment Information Model for Wavelength Switched Optical Networks" (RFC 7446) shows what information is required at specific points in the WSON. Part of the WSON information model contains aspects that may be of general applicability to other technologies, while other parts are specific to WSONs. + This document provides efficient, protocol-agnostic encodings for the WSON-specific information fields. It is intended that protocol- specific documents will reference this memo to describe how information is carried for specific uses. Such encodings can be used to extend GMPLS signaling and routing protocols. In addition, these encodings could be used by other mechanisms to convey this same information to a Path Computation Element (PCE). + + + + + + + + + + A YANG model to manage the optical interface parameters for an external transponder in a WDM network + + Cisco + + + Deutsche Telekom + + + Juniper + + + Juniper + + + + 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 by in phase of specification by) ITU-T G.698.2 or any + other ITU-T recommendation. Use cases are described in RFC7698. + + 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.
