RE: Re: gnet + scientific applications

Yes it is a P2P network, but:
* it is asymetric (there's a central server in each project for coordinating
things, which performs very different things than clients; there's no
"servent")
* and networking is not used all the time (clients have a large autonomy,
and networking support is not even required, given that what is really
exchanged is a set of files, using any usable file transmission system;
networking is only needed when getting work units or sending results to the
central server, but this may be done on another system, for example by using
independent caching proxies working asynchronously).
* The whole topology of a BOINC project is not a mesh but a star with two
levels; that's basically the same topology as classic web browsing.

If you want a better match of P2P systems, that predates BOINC since long
you need to consider first the Internet DNS system which is more closely
related to Gnutella, because almost all hosts can act both as a client and
as a server for other hosts.

Another old P2P system is the network transporting IP routing information on
the Internet (today, it works on top of a DNS system that is used to record
the routes locally in small clusters, and with gateway-to-gateway
protocols). The P2P system is basically in these gateway-to-gateway
protocols (RIP, IGMP, ...)

These two examples have predated all "modern" P2P system since several
decennials. These were the foundation of the Internet by allowing
independent networks to interact with each other and acting as equal peers,
and discovering each other in a mesh of networks.
