Technical Summary
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. 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.
Working Group Summary
Working consensus for requirements was honed over 6 months (May -Nov 2015).
WG LC done on individual draft 5/26/2015 to 6/9/2015
WG LC done with All of requirement drafts 10/6/2015 to 10/20/2015
Document Quality
Are there existing implementations of the protocol? Have a
significant number of vendors indicated their plan to
implement the specification? Are there any reviewers that
merit special mention as having done a thorough review,
e.g., one that resulted in important changes or a
conclusion that the document had no substantive issues? If
there was a MIB Doctor, Media Type, or other Expert Review,
what was its course (briefly)? In the case of a Media Type
Review, on what date was the request posted?
