We ran a permanent host during the month of February 2004 in
Poschiavo, Switzerland. GPU was running on an Internet Access Point hidden
from the user's view. All GPUs around the world automatically connected to
this node at startup; using the IP recorded in the logfile of the permanent
host we were able to tell from which country the connection came from.
Connections from around the world to a host in Switzerland
We first thought that TCP/IP timeouts might shape Gnutella in geographical
clusters. However, TCP/IP proved itself very reliable and we recorded
connections from everywhere, including countries like Brasil,
China and Japan. Gnutella is probably very close to a random graph with no
geographical clustering features.
