Abstract

   This document describes the distributed data export 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.

Requirements Language

   The key words "MUST", "MUST NOT", "REQUIRED", "SHALL", "SHALL NOT",
   "SHOULD", "SHOULD NOT", "RECOMMENDED", "MAY", and "OPTIONAL" in this
   document are to be interpreted as described in RFC 2119 [RFC2119].
