 An Extension to the REsource LOcation And Discovery (RELOAD) Protocol
                     to Support Relay Peer Routing

Abstract

   This document defines an optional extension to the REsource LOcation
   And Discovery (RELOAD) protocol to support the relay peer routing
   mode.  RELOAD recommends symmetric recursive routing for routing
   messages.  The new optional extension provides a shorter route for
   responses, thereby reducing overhead on intermediate peers.  This
   document also describes potential cases where this extension can be
   used.
