Main focus is given to the current concept - massive distributed transparent caching.
We deployed cooperating cache farms in most major network nodes and developed software to coordinate cache configurations. As a result, most of our users' requests are being cashed. TEN-155 CZ is the Czech national research and academic network. It connects all Czech universities and most institutions of the Czech Academy of Sciences. About 30,000 computers and more than 100,000 people are using this network.
