Hi WG,

The draft-ietf-netconf-udp-pub-channel-00(https://tools.ietf.org/html/draft-ietf-netconf-udp-pub-channel-00) was adopted with two parts content, one regards to the distributed data collection and the other regards to the UDP publication channel.

During the DT discussion, we decided to extract the distributed data collection part, generalize this topic and generate a new draft: draft-zhou-netconf-multi-stream-originators-00 (https://tools.ietf.org/html/draft-zhou-netconf-multi-stream-originators-00).

While preparing the new revision, we look forward to your comments and suggestions on this new draft.

Abstraction:
This document describes the distributed data collection mechanism that allows multiple data streams to be managed using a single subscription. Specifically, multiple data streams are pushed directly to the collector without passing through a broker for internal consolidation.

Issues Being Worked:
*Subscription Decomposition
--Keep track of resources and the associated publisher
--Make decision on decomposing the global subscription into multiple component subscriptions.
*Publication Composition
--Compose the component notifications into one.
*Subscription Management
--Error codes related to the Subscription Decomposition and Component Subscription
*Notifications on Subscription State Changes
--Each component subscription maintains its own subscription state and is responsible for sending its own OAM notifications.
*Potential Issues
--Synchronization
--Configured Subscription and Call Home

Thanks,
Tianran
