Hi Dear all,

We've uploaded a new version of draft-liu-netconf-multiple-replies-01. This draft was briefly presented in Dallas.

Excuse my iteration, the main idea of the draft is that in some scenarios, multiple replies for a single request might be needed. These scenarios listed in the draft are:
- Bulk reply
  The reply message is huge, needs multiple fragments
- Persistent reply
  Some operations such as Pinging, Tracert need continuous replies for the request.
- Long time reply
  Some operations might take a long time to perform, might need responses returns monitoring progress till the final result
- Datastore push updates (newly added in the 01 version)
  This is regarding to the the i2rs requirements using Subscribing to datastore push updates, which will be discussed in the upcoming meeting.
  The datastore push problem is a comprehensive issue that needs considerations in Content, Operations and Messages layer in Netconf. 
  In our draft, we only cares about the Messages layer. draft-clemm-netconf-yang-push-00 proposed to extend the Notification messaging to fulfill the requirements. This draft proposes multi-replies messaging might also cover the requirements (it needs more discussion though). 

So, with these scenarios, do you think the Netconf need to be extended at the Messages layer to support multi-replies?
(Btw, this draft also briefly discusses two solution alternatives.)

Looking forward to your comments. Thank you.

Best regards,
Bing

Abstract:
   This document discusses several scenarios that multiple replies for a
   single request are needed, with the ability to terminate the replies
   at any time.  Such scenarios are not well supported by current
   NETCONF (Network Configuration) protocol.  An extention at the
   NETCONF messaging layer is needed to fulfill the requirement.

Please note that it may take a couple of minutes from the time of submission until the htmlized version and diff are available at tools.ietf.org.
