Utorrent question

[abhinav_sinha]

But, wouldn't "..\..\download" path is a relative one

Yes.
I tested it today after your post. Thanks for pointing out.
Actually I was testing it via Run and forgot that it is getting executed in c:\ thus opening it.

If Seeds r greater than Peers then also u will get good speed....

E.g. Seeds: 20(40) Peers:4(8)

But I am seeeing in many torrents seeds have dissappeared a little

I think if Seeds are good in number, (like 10, 20 or more) you WILL get a good speed, irrespective of number of Peers.

Glad, the confusion has been cleared.

What do you mean, disappeared? The numbers will always vary each time the torrent is restarted, as it reconnects.

Well, just like the editor of digit wrote, piracy is definitely starting to dissappear.....

But if Peers r greater than Seeds then it will be tough time for Seeds to give the download to each peers...

E.g.10 seeds & 40 peers means ratio is 1:4 so each seed will allocate upload to 4 Peers...& if 10 seeds & 20 peers than ratio is 1:2 so each peers will get good speed

It works slightly different to that. Cause data flows in small pieces. And also once you receive, you start to seed back...!

Theoretically, your statement makes sense. But practically that just doesn't justify the problem.
First, it rarely happens that a peer are connected with EACH and every seed. And also, no ONE seed, is distributing data to ALL the peers. So the ratio which you mentioned just isn't perfect.
Second, as asingh explained, a peer also distributes data. A few peers can collectively act as a seed. So, in many situations, all the data can be distributed over just by peers!

I have made a dirty diagram to show this concept:

But if I m downloading a file then i m also counted as peers coz i m also uploading data...

& u r true the seed giving parts to peers keeps changing....

but remember dat peers doesnt have full data file.& u cant get the whole file only from peers there shud be atleast one seeder to get 100% file

Peers and Seeders both can upload data. It is not necessary that a seeder be available to complete the file. I could have "part" which can completed via peers. Just remember the full file is never gotten from one seeder. It is always from different people on the end nodes.

Though if there are no peers and only one seeder -- then the DL'er is dependent on that one seeder.

Exactly true.

I never said that. But you are true again.

I think you will have to read my previous post again. I had explained this point only. I had made this statement, "A few peers can collectively act as a seed.", which explains your above quote.

Torrents are turning out to be very complicated. I thought they were pretty simple but they are not!

Nothing is simple, if you look too closely. And yet, everything is simple, if you understand it.

I just downloaded a torrent to see my upload download speeds,,,,

Was surorised to see that my upload speeds reached 10 kbps although I was just downloading.

 

[Zangetsu]

"A few peers can collectively act as a seed."

True only if adding all the peers data makes a whole file.but if a single piece is not there in all the peers then no use only a seeder comes into play

Happens with me too. I guess those are just false readings for a few seconds, when a new torrent starts.

Are you assuming the nature of downloading, from seeds/peers to be static. It isn't. Remember, the peer who is providing you data, is also downloading its remaining data from somewhere else. So by the time, you will need a piece of data, it can be possible that the peer have d/w'ed it in the meantime.

BTW, I think, this discussion have gone way over-board. I suppose, its quite clear now, how torrent works!

 

[Vyom]

I still find them very complex. I though a .torrrent file just contined info about ip where the entire file is located. But now their working is very very complex.
Phew.

From Wikipedia:

The torrent file contains metadata about all the files it makes downloadable, including their names and sizes and checksums of all pieces in the torrent. It also contains the address of a tracker that coordinates communication between the peers in the swarm.

Have you opening a torrent file in notepad? Its unreadable after first few lines. But the sheer amount of data inside it, is just overwhelming!
So yeah, it IS very complex.

 

[thetechfreak]

Removed

Copy paste of a .torrent file....few website names removed and file size= 2 kb

 

[Vyom]

^^ Purpose of posting that??
Yeah, we can see, it contains URL's of trackers.

 

[asingh]

Basically it is a descriptor file.

 

[Zangetsu]

We can see the list of peers connected with their IP addresses...& their port nos...

if i change my port no to say 50000 which same as a peer in the list then what will happen?

 

[asingh]

You will need to reacquire the peers again.

Ok...I saw in preference tab "Apply Limit to uTp Connections" was checked & I unchecked it...what does it do?
