   Self-tuning Distributed Hash Table (DHT) for REsource LOcation And
                           Discovery (RELOAD)
                  draft-ietf-p2psip-self-tuning-15.txt

Abstract

   REsource LOcation And Discovery (RELOAD) is a peer-to-peer (P2P)
   signaling protocol that provides an overlay network service.  Peers
   in a RELOAD overlay network collectively run an overlay algorithm to
   organize the overlay, and to store and retrieve data.  This document
   describes how the default topology plugin of RELOAD can be extended
   to support self-tuning, that is, to adapt to changing operating
   conditions such as churn and network size.
