 ALTO-Like Activities and Experiments in P2P Network Experiment Council
                  draft-kamei-p2p-experiments-japan-08

Abstract

   This document introduces experiments to clarify how ALTO-like
   approach was effective to reduce network traffic made by a Council in
   Japan to harmonize P2P technology with the infrastructure.  And this
   also provides some suggestions that might be useful for ALTO
   architecture learned through our experiments.

1.  Introduction

   An overlay network, which is used by P2P and other applications,
   offers the advantage of allowing flexible provision of services while
   hiding the lower layer network.  The downside is that inefficient
   routes are often taken in the lower IP network, thereby increasing
   the network load.  Several proposals have been made to build an
   overlay network that takes account of the information about the lower
   layer network. [1] [2] Since the management of the Internet is highly
   distributed, it is difficult to implement such proposals and thus
   optimize a network without the cooperation of network providers.

   Recently, the controversy between the overlay network and the network
