Abstract

Applications interacting with YANG datastores require capabilities beyond the traditional client-server configuration of network elements. One class of such applications are service-assurance applications, which must maintain a continuous view of operational data and state. Another class of applications are security applications, which must continuously track changes made upon network elements to ensure compliance with corporate policy.

             Requirements for Subscription to YANG Datastores

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.
