Dear WG,
We submit a new draft draft-zheng-netconf-fragmentation-00.
This draft present a mechanism which allows NETCONF to handle large size data as fragmented RPC messages.
For example, in some scenarios, the <rpc-reply> message might be very large.  Such as, when NMS is retrieving a large amount of routes in a core router or doing a full-synchronizing with a device, the <rpc-reply> data might exceed Mega-Byte amount.  Or the client want to retrieve a continuous stream of operational data from the operational datastore to perform network analytics.

To address this problem define a new rpc <get-block>, which can help to retrieve the large size reply:
-There should be a Max-Size for fragmentation. E.g. 64K bytes.
-When the message reaches the Max-Size, it is sent to the client and the next message could be created in advance.
-Using <get-block> to retrieve the fragmented blocks and using <discard-fragment> to terminate.

More details please see the document, the links are shown below. Please review it, comments and suggestions are welcome!

Best Regards!
-Michael

Abstract:
   This document introduces an extension to NETCONF (Network
   Configuration) protocol.  The extension allows NETCONF to handle
   large size data as fragmented RPC messages.  Specifically, this
   document defines a new <get-block> capability and relevant operations
   to handle the fragmentations.

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.
