Morgwen, you're amazing.

I think I've mined your mind enough for the time being, so I'll keep my mouth shut for a while and give you a breather.

Well, I guess I do have one question: What do you do there in Germany? Do you teach on this subject, because your explanations are so precise and to the point.

If you ever write a book on this kind of stuff, let me know so I can pre-order it on Amazon.com!

Cheers,

No!

I "translate" what I have learned, nothing more.

Also you may want to consider that a user's reported connection speed may not be the best indicator of how quickly you can transfer files with him/her. Downloading from users with a four star quality rating will help you find the best connection speed possible.

I'll ask only one more question.

Does Limewire keep track of my broken downloads by the IP of the host?

If it does, this would be the answer for why I don't seem to resume downloads from some hosts.

In the meantime: thank you guys for the anwers for the questions I did not have to ask... Just now I begin to understand how this P2P thing works.

Oh, just one more question: why is the TTL of the query so small? Would a larger TTL clog the network?

Thanks.

Ajutagir,

Thanks for your response!

And as with most responses, it leads me to yet ANOTHER question:

What does Limewire do to determine if someone is a four-star rating? Do you Ping them somehow as Morgwen suggested? If so, Morgwen said that that's not always reliable. Couldn't they be a four-star rating one second and a one-star the next depending on their activity?

The reason I ask is that this dovetails with my question on how can I determine the speed of someone with whom I'm uploading or downloading a file. Can I rate the person myself? (By the way, how do I refer to someone I'm uploading or downloading with? Are they a "host" or...?)

Thanks!

Kind of off topic but....

I was wondering about Ethernet connections. Namely, 10Mbps vs. 100Mbps and Half-Duplex vs. Full Duplex. Are these two things independant from each other? What I mean is can you have four different combinations like 10Mbps Half Duplex, 10Mbps Full Duplex, 100Mbps Half Duplex, and 100Mbps Full Duplex?

Or is it only two? Like 10Mbps is only Half Duplex and 100Mbps is Full Duplex?

Thanks in advance...

I think I know a couple of these...

Moe:

Yes. It's just like the requery function. If a few thousand users really were sending 5 or 6 requeries every 300 seconds, and queries were allowed to hop to 15 hosts, there would be a ton of congestion.


I'm not sure about that, but it could very well be that a four-star host suddenly filled his upload slots or signed off before you got a chance to connect to him. Napster's ping results were always very reliable for me; however, I think a DOS ping command doesn't follow the same route to the pinged host as your file transfer will, so it won't be an accurate estimate of speed.


Sounds good to me.


mdouma46:

10 Mbps and 100 Mbps are bandwidths, just like a 56 kbps modem (except a few thousand times faster). It means 10 million bits per second, or 1.25 million bytes per second (8 bits in a byte). Your nicer university networks run 100 Mbps, and home networks are usually 10 Mbps. You can say "ten mega baud" if you don't like "ten million bits per second."

You have an maximum upload speed and a separate maximum download speed. According to this speed test, I can run 350 kB/s on uploads and about 1.5 MB/s on downloads. If your network card is capable of full-duplex, you can upload and download something to and from a host simultaneously. In half-duplex mode, you can be sending or receiving, but not both. I was under the impression that under full-duplex, you were guaranteed both your maximum upload and download speeds at any given time, whereas in half-duplex, a heavy download could deplete some of your upload bandwidth. I may be misinformed.

Hoping there's at least one truthful sentence in this post,

Thanks, for the response, Brandan!

I'm not sure, but I think that reading this thread can get you college credits at most Universities!

To all you guys who have, politely and without smartypantsness, helped us rookies understand the mysteries of file sharing, thank you so much!

Of course, that doesn't mean I'm done asking questions...
