The “Cache Discovery Protocol” is already implemented in the latest version of the mainline client The protocol allows ISP’s to detect the most popular torrents, cache the data, and seed it. ISP’s like it because it’s cheaper to use bandwidth within their network than to use external traffic.
So in the near future it could be that you’re downloading your favorite torrents from your ISP’s server instead of some random seed or peer at the other side of the globe.
Currently, “regular” BitTorrent is traffic is suffering from throttling ISP’s that claim that BitTorrent traffic is cluttering their pipes. This morivated the developers of the most popular BitTorrent clients implement encryption to protect BitTorrent users from being slowed down by their ISP’s.
However, Bram Cohen, the creator of the BitTorrent protocol and the developer of the mainline BitTorrent client did not believe that encryption was the solution, and found (tohether with Cachelogic) a more ISP friendly alternative. However, this new and improved version is promising the opposite, downloads will be accelerated instead of throttled. However, only for commercially licensed content.
Ashwin Navin, President and Co-founder of BitTorrent states:
“CacheLogic has developed an innovative solution to address a major problem that all ISPs face with respect to network congestion. Today, people use the Internet for many bandwidth-intensive services and consumers are increasingly aware of the quality of service needed for their favourite applications. With the popularity of BitTorrent usage worldwide, ISP networks are being taxed in a way they weren’t designed for. As a remedy to this, the Cache Discovery Protocol is providing carriers with an economical and scalable solution that improves the end-user experience for applications that consumers are growing to love.”
