"The network, dubbed the Infrastructure for Resilient Internet Systems (IRIS), will speed up searches and information transfer over the internet, and aims to foil "Denial of Service" attacks by hackers - in which a web server is swamped with requests for a page until it crashes."
"IRIS is being designed specifically to solve these problems. Its three design criteria are to guarantee:
• that as long as there is no physical break in the network the target file will always be found;
• that adding more information to the network will not affect its performance;
• that machines can be added and removed from the network without any noticeable adverse affects. "
