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.
This document is a product of the Interface to the Routing System Working Group of the IETF.
