Making BitTorrent Clients Prioritize By Geography?

Posted by timothy on from the hey-you're-blocking-my-bandwidth dept.

Daengbo writes "While I live in S.Korea and have virtually unlimited bandwidth in and out of the country, not all my Asian friends are so lucky. Many of the SE Asian and African countries have small international pipes. Even when a user has a high-speed local connection, downloads from abroad will trickle in. Bittorrent clients apparently don't prioritize other users on the same ISP or at least in the same country. Why is that? Is it difficult to manage? If I were to write a plug-in for, say, Deluge, what hurdles would I be likely to come across? If this functionality is available in other clients or through plug-ins, please chime in."

  1. Azereus already has a plugin for this by dave562 · · Score: 4, Informative

    There is already a plugin for Azereus that does this. I downloaded it about a year ago. I'm at work right now or otherwise I would look at my installation and tell you the exact name of it.

      Is that the same plugin that constantly runs a barrage of pings in a hidden shell? Can't remember the name, but I ran a similar sounding plugin and didn't see much speed improvement but it sure did chew up my CPU.

      It is called Ono and it can be found here

    uTorrent has a feature called local peer discovery that does that exactly. It was even able to discover other people at my university sharing the files.

      Local peer Discovery works only within a lan, the corresponding broadcast messages are not routed over the internet

  3. Ono by pythonax · · Score: 5, Informative

    There is a plugin for Vuze (formerly Azureus) called Ono which does exactly that. Not sure what the problems they ran into, but as it is a college project I am sure they would be willing to discuss some of it with you. http://www.aqualab.cs.northwestern.edu/projects/Ono.html

  4. Already Made "Ono" by StarWreck · · Score: 4, Informative

    What you're looking for is an Azureus plugin called "Ono". It prioritized based on router hops. Theoretically, this would make those connected to the same ISP preffered. After that it would make ISP's with direct connections to your ISP preferred. After that, resonably close geographically, ie same country.

  5. For Vuze, there's Ono and P4P by chrysrobyn · · Score: 5, Informative

    For Vuze, formerly Azureus, there are Ono and P4P, which should do what you're looking for, although for different reasons. Unfortunately, they both rely on people in your region being interested in the same torrents you are, while P4P additionally benefits from an iTracker, an ISP provided tracker that's topology aware (they did some work to prioritize based on ping latency, using that as a distance estimate, but I don't know if it's a fallback mechanism). Due to the iTracker infrastructure and possibly conflicting supporters, there are some privacy concerns.

  6. Tune your TCP Receive Window first by WinDev · · Score: 5, Informative

    The biggest speed issue facing Asia/Australia is the latency of traffic to the rest of the planet. The (Windows) TCP Receive Window is tuned too small for the distances required. If you change the receive window to the maximum, you can get 4x more data in the same period using any client (P2P, browsers, etc...).
