utorrent 3.4 adds Canonical Peer Priority

[mikezilla2]

The uTorrent development team officially released the long-awaited version 3.4 release of their popular BitTorrent client a few hours ago. The new release completely changes the way uTorrent chooses peers in a swarm, which ultimately improves download speeds while preventing DDoS attacks.

With well over 150 million active users a month uTorrent is by far the most used BitTorrent client.

The popular application began as a minimalist and no-nonsense client targeted at a BitTorrent-savvy crowd, but evolved into a feature-rich download tool during the years that followed.

This week the uTorrent development team released uTorrent version 3.4. Aside from the standard bug fixes, new features and aesthetic upgrades, the latest release includes one of the most significant changes in years.

Spearheaded by BitTorrent developer Arvid Norberg, the new release includes a new method of connecting people who are sharing the same file. This change is welcome, since the traditional way of choosing peers has some major drawbacks.

“If [a BitTorrent client] chooses poorly, or if there are malicious actors in the swarm, the connections between clients are not well distributed through the swarm, leading to a large number of hops from node to node. That slows down the ability to each client to pass data on to the next,” BitTorrent’s Adam Kelly explains.

With Canonical Peer Priority, as it’s called, peers will no longer be selected on a first come first serve basis.

The new peer selection method will now give priority to peers who are close in the network (fewer hops away). This means that when uTorrent has reached the maximum number of connections for a torrent, it will still accept incoming peers with a higher priority.

Instead of refusing the connection of the new peer, it will accept it and kick out a lower priority peer. This will help peers to connect to each other faster, and also reduce the distance between peers, which ultimately results in faster downloads.

In addition to increased connection times and faster downloads, the new peer selection method also prevents DDoS attacks against larger swarms.

With the old method malicious parties could flood a swarm with download requests, pretending to offer a piece of the file. By doing so, they could lock up dozens of connection slots, seriously degrading download performance by taking up space of legitimate peers.

“There’s an opportunity to DDoS a swarm by filling up everyone’s connections slots, and continuously making incoming connections at such rate that peers won’t have an opportunity to connect to anyone else,” Norberg explained.

With the new selection method this problem is solved, as low priority peers will be swapped out for newcomers who have real data to offer.

uTorrent users are not expected to notice a difference right away. The effectiveness depends on how many other peers in the swarm use uTorrent 3.4, which will be relatively low for now. However, as time changes this is expected to pick up. Whether other BitTorrent clients plan to implement the same technology has yet to be seen.

In addition to the new peer selection method and other improvements, the uTorrent team also announced that it will release newer versions of the software more quickly. In recent month there have been some complaints in the forums from users about a lack of updates and fixes.

BitTorrent Inc. has put more developers on uTorrent, so fixes and new features are expected to come out faster in the months to come. This is expected to include a paywall to unlock premium bundles from artists.

 

old news but wondering what everyone thinks ?

I wouldn't recommend the newer utorrent. There is just too much shit baked into it. Media players, device syncing, ratings? Oh, and ads, don't forget the ads. (I know one can 'disable' the ads etc., but simply hiding them is not a solution.)

And as for the new peer selection method: If it gets adopted by the more important clinets (i.e. rTorrent/libTorrent, Deluge etc.) then great. If it doesn't... then great. It makes no difference to the people who use real torrent clients.

Note: I use utorrent 2.2.1 as my main Windows torrent client because everything sucks.

I think this should be stressed more. Many seedboxes don't offer μTorrent as default client (my offers it as alternative), because of this, it will not make big changes for private trackers with large torrents (like ADC).

Checking some of torrents I am seeding/leeching currently, I saw clients like BitComet, Xunlei, QQDownload, μTorrent 1.6.1, BitTorrent, libTorrent, Torch, Mainline, Transmission and qBitTorrent (among others), so I don't see this changing much for users like me (anime downloaders).

As for new versions of μTorrent, I am with JohnFlower. There are too may unnecessary junk I could live without, not to mention technical problems I had with it. Older versions work just fine, and I am still using μTorrent 2.2.1.

it's great/nice and all, but i refuse to upgrade until they stop those ridiculous spam ads.

The problem I have with the new version is it keeps saying finding peers and stays that way when going through BakaBT.

You can't upgrade torrent clients, till BakaBT adds them to their whitelist; or you will not be able to use BakaBT.

Yeah I know.     I just hope they update
