| Proxy Profiles |
|---|
Ten Squid proxies participated in our study so far. For each proxy, we collected at least one day worth of logs. The proxies represent all levels of caching hierarchy starting with leaf university proxies and ending with the root proxy of NLANR international hierarchy. We are still expanding our collection with new proxies for future experiments. Here we summarize important facts about participating proxies.
