            Application Layer Multicast Extensions to RELOAD
               draft-irtf-samrg-sam-baseline-protocol-04

Abstract

   We define a RELOAD Usage for Application Layer Multicast as well as a
   mapping to the RELOAD experimental message type to support ALM.  The
   ALM Usage is intended to support a variety of ALM control algorithms
   in an overlay-independent way.  Two example algorithms are defined,
   based on Scribe and P2PCast.
