Abstract

   This document describes the distributed data export mechanism that
   allows multiple data streams to be managed by using a single
   subscription.  Specifically, device can decide to decompse one
   subscription into multiple subscriptions to the line-cards.  So that
   each line-card can directly push data to the collector without
   passing through a broker for internal consolidation.  And the device
   can indicate the subscription decomposition result to the receiver to
   check the data integrity.
