Active Drafts • WG Draft: • NETCONF Event Notificationsdraft-ietf-netconf-notification-04.txt • Individual Submissions: • Netconf System Architecturedraft-atarashi-netconfmodel-architecture-03.txt • Experience of implementing NETCONF over SOAPdraft-iijima-netconf-soap-implementation-01.txt • Generic Action RPC for Netconfdraft-lengyel-action-rpc-00.txt • Netconf Master-agent Sub-agent Communication Protoc'ldraft-kulkarni-netconf-subagent-prot-00.txt

  6. Agenda • Agenda bashing and other administrativia (5') • NETCONF notifications (as long as it takes) • Experiences with NETCONF over SOAP (5', if time permits)

  7. notification-04 issues • Meta-issue: apparent lack of thrust • 4th meeting on this doc (including interim) • little review, slow convergence • would like to WGLC before next meeting • Suggested approach • Reduce to include only essential mechanisms

  8. notification-04 issue: datamodel • I-D includes extensive (read-mostly) data model • Application of “eat or own dog food” • Introduces (as done here) a normative reference on datamodel draft • Do we need to query subscriptions? • Do we need to query event streams?

  9. notification-04 issue: filtering • Several ways of selecting notifications: • event streams • one or 1–n per subscription? (StreamsList) • filters • XPath and subtree • specified ad-hoc or by reference to named profile

  10. notification-04 issue: replay • Retrieval of saved notifications possible • could use normal <get>? • No combined replay/real-time (“tail -f”) • replay followed by real-time notifications • “temporal ordering” problem • Balasz suggests to address this by deferring live notifications on a session during replay • Client can specify start- but not end-time
