I think it important that whatever we do in NETCONF we can also do in RESTCONF.   To that end, I support the WG defining "yang-push” for both protocols.

Actually, I’m a little surprised that we’re discussing this.  Maybe it’s just me, but when the WG adopted draft-ietf-netconf-yang-push, I thought that it would cover both protocols eventually.   Perhaps that a separate draft has been produced is another surprise here - do we really need another draft?

NETCONF:

These drafts is important to the I2RS pub/sub.   Is the RESTCONF draft going to be adopted (draft-voit-restconf-yang-push-00.txt)?

It would be really helpful.

Subject: [Netconf] New YANG PubSub drafts for NETCONF, RESTCONF, HTTP/2

There are a couple new drafts posted in NETCONF:

(1)  Subscribing to YANG datastore push updates
http://www.ietf.org/id/draft-clemm-netconf-yang-push-02.txt
As per earlier NETCONF discussions<http://www.ietf.org/mail-archive/web/netconf/current/msg10432.html> we are expecting this draft to become draft-ietf-netconf-yang-push in the coming days (once the NETCONF charter is approved).  Look for an OpenDaylight client in the Beryllium release (Feb).

(2) Restconf subscription and HTTP push for YANG datastores
http://www.ietf.org/id/draft-voit-restconf-yang-push-00.txt
Extends draft-clemm-netconf-yang-push in the following ways:

·     proposes Restconf subscription and push mechanisms to continuously stream information from YANG datastores over HTTP

·     provides a mechanism to support static subscriptions so that an operator can stream updates over HTTP without Restconf

·     provides YANG model extensions to leverage HTTP/2 so that individual subscriptions can get custom treatment via their own HTTP streams.

Thanks for your interest, and we look forward to the discussions!
