  Service Discovery Usage for REsource LOcation And Discovery (RELOAD)
               draft-ietf-p2psip-service-discovery-08.txt

Abstract

   REsource LOcation and Discovery (RELOAD) does not define a generic
   service discovery mechanism as a part of the base protocol.  This
   document defines how the Recursive Distributed Rendezvous (ReDiR)
   service discovery mechanism used in OpenDHT can be applied to RELOAD
   overlays to provide a generic service discovery mechanism.

Internet-Draft     Service Discovery Usage for RELOAD      February 2013

1.  Introduction

   REsource LOcation And Discovery (RELOAD) [I-D.ietf-p2psip-base] is a
   peer-to-peer signaling protocol that can be used to maintain an
   overlay network, and to store data in and retrieve data from the
   overlay.  Although RELOAD defines a Traversal Using Relays around
   Network Address Translation (TURN) specific service discovery
   mechanism, it does not define a generic service discovery mechanism
   as a part of the base protocol.  This document defines how the
   Recursive Distributed Rendezvous (ReDiR) service discovery mechanism
