  Service Discovery Usage for REsource LOcation And Discovery (RELOAD)
               draft-ietf-p2psip-service-discovery-15.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.

1.  Introduction

   REsource LOcation And Discovery (RELOAD) [RFC6940] 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
