The NETCONF Working Group, previously named after the NETCONF protocol, now renamed as the NETwork CONFiguration Working Group, is responsible for the development and maintenance of protocols for YANG data model driven management, for the necessary framework where these protocols run, and for the YANG modules that formalize protocol behavior and are required from a protocol perspective. The NETCONF protocol (RFC 6241) provides mechanisms to install, manipulate, and delete the configuration of network devices. NETCONF is based on secure transport (SSH is mandatory to implement while TLS is an optional transport). The NETCONF protocol is data modeling language independent, but YANG (RFC 7950) is the recommended NETCONF data modeling language, which introduces advanced language features for configuration management. The NETCONF WG recently finalized the development of the RESTCONF protocol (RFC 8040) which provides an interface over HTTPS for accessing data defined in YANG. RESTCONF is based on the capabilities of, and uses the datastore concept defined in, the NETCONF protocol specification. In support of RESTCONF the YANG Patch (RFC 8072) mechanism has been provided for applying patches to configuration datastores. The YANG Module Library (RFC 7895) provides information about all YANG modules used by a network management server. Last but not least NETCONF and RESTCONF Call Home (RFC 8071) have been developed, which enable a server to initiate a secure connection to a NETCONF or RESTCONF client respectively. In the current phase of NETCONF's incremental development the Working Group will focus on following items: 1. Finalize the YANG data module for a system-level keystore mechanism, which can be used to hold asymmetric private keys and certificates that are trusted by the system advertising support for this module. Based on the known dependencies this draft has the highest priority for the WG. 2. Finalize Server and Client Configuration YANG modules for both NETCONF and RESTCONF as well as the Client and Server Models for SSH and TLS. 3. Finalize the Zero-touch provisioning for NETCONF or RESTCONF-based Management as a technique to establish a secure network management relationship between a newly delivered network device configured with just its factory default settings, and the Network Management System. 4. Provide a revised version of RFC 6536 (NETCONF Access Control Model) by adding support for RESTCONF and for YANG 1.1 constructs like "action" and the (locally-scoped) "notification" statements. 5. Provide a set of documents enabling advanced notification/subscription capabilities, which gracefully co-exist with deployments of RFC 5277. The new capabilities include transport independence and multiple dynamic and configured subscriptions in a single transport session. RFC 5277 will be obsoleted in parallel with the publication of the new document set. The following specifications will be published: - A protocol-neutral notification framework, explaining the concepts of subscriptions, filters, subscription state notifications, replay, etc. and defining the associated YANG data model, RPCs, etc. - Definition of notifications sent over NETCONF and HTTP. Examples for the encoding of YANG notifications in XML and JSON will be given and considerations for parallel support and implementation compatibility with RFC 5277 will be included. - Definition of notifications sent over RESTCONF and HTTP2 and of how YANG notifications are encoded in XML and JSON, including specifics of call-home and heartbeat for subscriptions. - The subscription and push mechanism for YANG datastores allowing subscriber applications to request updates from a YANG datastore. - Definition of transport agnostic notification headers and of a mechanism for bundling multiple YANG notifications into a single transport message. 6. Based on the revised datastore concept work in NETMOD, provide a revision for the NETCONF and RESTCONF protocols and the used datastore framework. 7. Define capabilities for NETCONF and RESTCONF to support I2RS protocol and ephemeral-state datastore requirements. Based on the implementation, deployment experience and interoperability testing, the WG aims to produce a NETCONF status report in a later stage. The result may be clarifications for RFC6241 and RFC6242 and addressing any reported errata.
