Self-tuning Distributed Hash Table (DHT) for REsource LOcation And
Discovery (RELOAD)
draft-ietf-p2psip-self-tuning-14.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.
