What is CoDeeN?

CoDeeN is an academic testbed Content Distribution Network (CDN) built on top of PlanetLab by the Network Systems Group at Princeton University. This testbed CDN consists of a network of high-performance proxy servers. Currently, proxy servers have been deployed on many PlanetLab nodes. These proxy servers behave both as request redirectors and server surrogates.

CoDeeN follows an opt-in model: to take advantage of CoDeeN's service, you need to make a small change to your browser's proxy configuration.

Here are some tutorials for your browser:

Privacy

All accesses via CoDeeN are logged, mostly to aid in identifying abuse and other forms of damage control. PlanetLab sometimes monitor these logs, report abuse, and release entries to aid in investigations. In case of suspicious traffic, PlanetLab may access URLs from the logs to determine what kind of content is passing through our network. PlanetLab are also using these logs in our own research, so they may be examined as needed for non-abuse reasons. For normal users, PlanetLab do not expect that we will intentionally release any personally-identifying information. To prevent abuse, some sites have requested we pass along the client IP addresses, and these are included with every request forwarded to those sites.
