Requirements for Subscription to YANG Datastores
RFC 7923, “Requirements for Subscription to YANG Datastores”, is an Informational document published in June 2016 by E. Voit, A. Clemm, A. Gonzalez Prieto. The canonical text is published by the RFC Editor.
Abstract
This document provides requirements for a service that allows client applications to subscribe to updates of a YANG datastore. Based on criteria negotiated as part of a subscription, updates will be pushed to targeted recipients. Such a capability eliminates the need for periodic polling of YANG datastores by applications and fills a functional gap in existing YANG transports (i.e., Network Configuration Protocol (NETCONF) and RESTCONF). Such a service can be summarized as a "pub/sub" service for YANG datastore updates. Beyond a set of basic requirements for the service, various refinements are addressed. These refinements include: periodicity of object updates, filtering out of objects underneath a requested a subtree, and delivery QoS guarantees.
