[02:35:10] <TheSHAD0W> And what implications does this have for the internet?
[02:35:11] <TheSHAD0W> http://www.wired.com/wiredscience/2010/02/looped-leaf-networks/
[02:39:02] <The_8472> uh, something we already knew. that static routes are a bad idea
[02:39:40] <The_8472> if some peering link is severed packets _should_ find alternative routes
[02:39:47] <The_8472> but they can't if they're configured statically
[02:39:50] <The_8472> so... yeah
[02:39:55] <alus> the internet is not a tree
[02:40:13] <The_8472> not everywhere, no
[02:40:28] <The_8472> but in some areas it's very tree-like
[02:40:49] <alus> also note: trees are not like leaves
[02:41:05] <alus> branches of a tree do not connect to themselves
[02:41:07] <The_8472> ty captain obvious :)
[02:41:55] <The_8472> i think some root networks can though

[13:49:59] <pevangelista> Hello, all!
[13:51:15] <pevangelista> I have a question about when a peer just entered a swarm.
[13:51:16] <pevangelista> There is the optimistic unchoke and the unchokes dependent on upload rate to the client.
[13:51:54] <pevangelista> So, the client just entered the swarm and he is not downloading data from anyone
[13:52:17] <DeHackEd> there's also seeds who don't care about upload rate
[13:52:23] <pevangelista> Therefore, he will only upload data to the optimistically unchoked peer?
[13:52:50] <pevangelista> @DeHackEd: Is that a mod?
[13:52:58] <DeHackEd> no
[13:53:58] <pevangelista> I have to study the seed mode yet
[13:55:21] <DeHackEd> oh dear
[13:55:34] <pevangelista> One thing at a time
[13:55:50] <DeHackEd> I fear you've got your things out of order
[13:57:04] <pevangelista> How so?
[13:57:29] <DeHackEd> If you don't know what a seed is, I'm not sure now's a good time to start studying the protocol internals
[13:58:00] <pevangelista> I know what a seed is!! And I also know that the protocol for unchoking peers differs from a seeder and a leecher
[13:58:42] <pevangelista> I mean, there is no sense for a seeder to use the transmission rate to classify the peers he unchokes
[13:59:29] <pevangelista> like, in the first specification, a leecher ordered the peers in its unchoke list based on their upload rate to the client, but when in seed mode, the download rate was used
[14:00:03] <kjetilho> makes sense to me?
[14:00:56] <pevangelista> but what about peers with lower bandwidth? They were left out of this list. The whole idea of the unchoking mechanism was to ensure fairness
[14:01:52] <kjetilho> the idea is that a fast downloader is a fast uploader, so it will help the swarm better
[14:27:01] <pevangelista> Here, I found another unchoking algorithm when in seed mode.
[14:27:25] <pevangelista> Every 10 seconds, the unchoked peers are ordered according to the time they were last unchoked.
[14:28:04] <pevangelista> The first two consecutive periods of 10 seconds the fourth most recent unchoked peer is choked and an additional random choked and interested peer is unchoked.
[14:28:49] <pevangelista> The third period of 10 seconds the 4 most recent unchoked peers are kept unchoked.
[14:29:07] <pevangelista> This way, each leecher in the swarm gets the opportunity to download from a seeder
[14:30:59] <pevangelista> considering that there can only be 4 unchoked peers simultaneously
[14:33:03] <pevangelista> So, that is why I said one thing at a time. I am studying the choking algorith when in leech mode, and when done, I will focus on the seed mode

[17:46:06] <skampler> is there any mainstream client out there which optimizes for consequtive read + writes to avoid disk seeks?
[17:53:13] *** goussx has joined #bittorrent
[17:54:04] <Andrius> "avoid disk seeks" and "bittorrent" don't really get along
[18:05:39] <kjetilho> I believe one of the superseeding implementations did some of it
[18:05:53] <kjetilho> don't know about clients
[18:06:40] <kjetilho> a client will need to write data from different pieces concurrently
[18:06:44] <FarmerSHAD0W> If a client implements piece-sized buffering, it tends not to make a lot of seeks.
[18:06:51] <kjetilho> yeah
[18:14:11] *** rot has joined #bittorrent
[18:25:08] <alus> skampler: most clients sort their disk jobs and do then in order

[20:38:25] <alus> how is too expensive "perfect"? :P
