Bittorrent Implements Cache Discovery Protocol 170
An anonymous reader writes "CacheLogic and BitTorrent introduce an open-source Cache Discovery Protocol (CDP) that allows ISP's to cache and seed Bittorrent traffic. Currently, Bittorrent traffic is suffering from bandwidth throttling ISP's that claim that Bittorrent traffic is cluttering their pipes. This motivated the developers of the most popular Bittorrent clients implement protocol encryption to protect bittorrent users from being slowed down by their ISP's. However, Bram Cohen, the founder of Bittorrent doubted that encryption was the solution, and found (together with CacheLogic) a more ISP friendly alternative."

How many people download Linux ISOs using BT? If 30 people on one ISP download a new release, and it's using this, the ISP saves about 20-30GB and the users get the full 300KB/s they pay for instead of 2-3KB/s.

Why don't they use multicasting? (Score:5, Insightful)
The sender can multicast the file in a loop. The recipients will get the pieces starting from whenever they started "listening" on the ongoing multicast, and then get the earlier parts, when the sender finishes and starts over again.
This is far more efficient, than for the sender to push the same data to each client in parallel.

Most networking researchers seem to believe multicast is technologically feasible and helpful, which is why a lot of Internet architecture research seems to provide methods for multicast, even though hardly anybody uses it today.

It's not GNU/Linux distributions that have caused ISPs to decide to bandwidth throttle bittorrents.
