Xelif - Download 30X faster with the Xelifaster!
Xelif improves the efficiency of the Internet by reorganizing data so that it is closer to you when you need it. Like an ice cream truck that brings the best ice cream to your block, Xelif ensures that popular data is close and quick to access. Imagine being able to download a 600MB movie from an online video store, and have it take just 30min? At that speed the movie can be streamed, so you can start watching immediately. Xelif can make this happen, not in a couple years, or once other technology is complete, but right now.

The Scarce Resource - Bandwidth
ISPs have long faced a problem with fairly allocating their scarcest resource; bandwidth. The practice of overselling bandwidth in an open unmetered network leads to a small percentage of users using a large percentage of the available bandwidth. Lacking an efficient solution to the bandwidth inequity problem, ISPs have turned to solutions that degrade network performance for some users. Traffic shaping limits the bandwidth of some users to less than what they pay for. The second option, creating a two-tiered Internet, leads away from the traditions of the Internet being an open and unbiased exchange of information. Until now the technology to equalize bandwidth usage for ISPs without harming consumers has not been available. Xelif can equalize bandwidth usage, and instead of doing this at the expense of the consumer, Xelif actually improves their network performance. Xelif's exciting technology leverages the fact that the Internet was not designed with content distribution in mind.

Content Distribution on the Internet
One of the last remaining technological problems on the Internet is the distribution of large files (or any large amounts of content). Even today, an average Internet user cannot simply post a 600MB video or popular 25MB video, in spite of the amount of unused bandwidth (dark fiber) available in the Internet core. Excess bandwidth in the Internet core hints that the content distribution problem has other roots besides lack of bandwidth. The Internet was designed to be a reliable method of exchanging information, and was not designed with large scale file distribution in mind. Various solutions to improve content distribution on the Internet have been attempted, like throwing a lot of server iron and bandwidth at the problem, but the expense of these solutions simply highlights their inefficiency. Peer-To-Peer is also an attempt to get around Internet limitations by spreading the bandwidth and computing requirements across many computers. The Peer-To-Peer approach also has several limitations however, most notably that downloads are typically slow. Slow downloads are a symptom of the fact that P2P does not address the underlying structure of the Internet, the peer you are downloading from may be in Europe, instead of in your city.

Increasing Internet Efficiency
The Internet as a whole is structured as a web of interconnected networks. To get a file which is hosted on one network to many other networks requires communication between the networks. Inter-network communication is known as transit bandwidth. This transit bandwidth is typically both expensive for an ISP and slower than sending files within the local network. To quickly and cheaply transfer a file, or any data, the ideal location for the file is hosted locally on each ISP's network.

Xelif provides a means of automatically reorganizing data on the Internet to meet local demands. This automatic reorganization means that popular data is localized to the areas where it is needed, leading to faster downloads for the end user, and bandwidth savings for the ISP. Instead of focusing on whole files Xelif treats each download separately, and simply "fills in the blanks" in the connection. Most often the Xelif server you are connected to may be in your city, or very close within the ISP's network

So does Xelif store popular files on a local server?
There is no concept of a "file" in the Xelif system, so files are not stored.

How do I tell what data Xelif has locally? How can I access data on the server?
Xelif only speeds up your connection, there is no way to directly access anything on the server.
