These volunteers keep the board organized and moving. Moderators are authorized to: (in order of increasing severity) Move posts to the correct forums. Many times, members post in the wrong forum. These off-topic posts may impede the normal operation of the forum. Edit posts. Moderators will edit posts that are offensive or break any of the House Rules. Delete posts. Posts that cannot be edited to comply with the House Rules will be deleted. Restrict members. This is one of the last punishments before a member is banned. Restrictions may include placing all new posts in a moderation queue or temporarily banning the offender. Ban members. The most severe punishment. Three or more moderators or administrators must agree to the ban for this action to occur. Banning is reserved for very severe offenses and members who, after many warnings, fail to comply with the House Rules. Banning is permanent. Bans cannot be removed by the moderators and probably won't be removed by the administration. The Rules 1. Warez, copyright violation, or any other illegal activity may NOT be linked or expressed in any form. Topics discussing techniques for violating these laws and messages containing locations of web sites or other servers hosting illegal content will be silently removed. Multiple offenses will result in consequences. File names are not required to discuss your issues. If filenames are copyright then do not belong on these forums & will be edited out or post removed. Picture sample attachments in posts must not include copyright infringement. 2. Spamming and excessive advertising will not be tolerated. Commercial advertising is not allowed in any form, including using in signatures. 3. There will be no excessive use of profanity in any forum. 4. There will be no racial, ethnic, or gender based insults, or any other personal attacks. 5. Pictures may be attached to posts and signatures if they are not sexually explicit or offensive. Picture sample attachments in posts must not include copyright infringement. 6. Remember to post in the correct forum. Take your time to look at other threads and see where your post will go. If your post is placed in the wrong forum it will be moved by a moderator. There are specific Gnutella Client sections for LimeWire, Phex, FrostWire, BearShare, Gnucleus, Morpheus, and many more. Please choose the correct section for your problem. 7. If you see a post in the wrong forum or in violation of the House Rules, please contact a moderator via Private Message or the "Report this post to a moderator" link at the bottom of every post. Please do not respond directly to the member - a moderator will do what is required. 8. Any impersonation of a forum member in any mode of communication is strictly prohibited and will result in banning. 9. Multiple copies of the same post will not be tolerated. Post your question, comment, or complaint only once. There is no need to express yourself more than once. Duplicate posts will be deleted with little or no warning. Keep in mind a forum censor may temporarily automatically hold up your post, if you do not see your post, do not post again, it will be dealt with by a moderator within a reasonable time. Authors of multiple copies of same post may be dealt with by moderators within their discrete judgment at the time which may result in warning or infraction points, depending on severity as adjudged by the moderators online. 10. Posts should have descriptive topics. Vague titles such as "Help!", "Why?", and the like may not get enough attention to the contents. 11. Do not divulge anyone's personal information in the forum, not even your own. This includes e-mail addresses, IP addresses, age, house address, and any other distinguishing information. Don´t use eMail addresses in your nick. Reiterating, do not post your email address in posts. This is for your own protection. 12. Signatures may be used as long as they are not offensive or sexually explicit or used for commercial advertising. Commercial weblinks cannot be used under any circumstances and will result in an immediate ban. 13. Dual accounts are not allowed. Cannot explain this more simply. Attempts to set up dual accounts will most likely result in a banning of all forum accounts. 14. Video links may only be posted after you have a tally of two forum posts. Video link posting with less than a 2 post tally are considered as spam. Video link posting with less than a 2 post tally are considered as spam. 15. Failure to show that you have read the forum rules may result in forum rules breach infraction points or warnings awarded against you which may later total up to an automatic temporary or permanent ban. Supplying system details is a prerequisite in most cases, particularly with connection or installation issues. Violation of any of these rules will bring consequences, determined on a case-by-case basis. Thank You! Thanks for taking the time to read these forum guidelines. We hope your visit is helpful and mutually beneficial to the entire community. |

Host Evaluation Some time ago, there was a discussion on this board about a scheme called Host Evaluation Number, or HEN, to increase the overall availability of files on Gnutella, which suffers a lot from the presence of so-called freeloaders (Hosts that don't share any or very few files or don't allow to download their shared at a decent bandwidth while at the same time downloading very much themselves). As I still think the idea is quite good and as it seems to have been more or less forgotten, I'm bringing it up again for discussion. The basic idea is to assign an 8 bit number (the HEN) with every host to indicate how much of a freeloader/generous sharer it is, and then give those hosts with a high HEN preference over those with a low HEN as soon as they try to download something. The HEN is calculated by dividing the number of uploaded bytes in all filetransfers during the last 48 hours through the number of bytes downloaded in the same time period and then multiplying the result with 128. (Thus, a HEN of 0 means the host hasn't uploaded anything; 128 means the host has uploaded as many bytes as it has downloaded; 255 means it has uploaded more than twice as much as it has downloaded.) If the host is an UltraPeer/Supernode/whatever-you-want-to-call-it, every byte transferred to or received from a Leafnode over a Gnutella connection counts as a byte uploaded in a file transfer. When Node now tries to download a file from another node, it sends its HEN as an additional HTTP tag along with the download request. If the sharing host has not yet reached its maximum number of simultaneous uploads, the HEN of the downloading host is stored and the download request is accepted. If the sharing host has already reached its maximum number of simultaneous uploads and if the HEN of the downloading host is more than 10 points higher than the average HEN of all the other hosts which are currently downloading from that sharing host, the sharing host opens an extra upload slot for the download requester. If even the number of extra uploads of this sharing host is reached and if the downloading hosts HEN is more than 20 points higher than the lowest HEN in the sharing hosts list of established downloads, the upload to which that lowest HEN belonged is cancelled and the new download request accepted instead. What do you think of this? |

Looks like you put some good though into that. Except, what about those that have recently joined Gnutella and don't have anything to share yet? How do they efficiently fill up their shared files pool? -- Mike |

While it appears that a lot of thought was put into this proposal and theoretically it would work to a degree, I'm generally not a fan of any ideas which remove or cripple anyone else's ability to use the network. The Gnutella network is supposed to be an open and free network. Participating freely on the network should not rely on whether someone has uploaded anything at all. All in all, using this proposal I forsee those people with T1 and higher getting the most preferencial treatment above all. They are ultimately the ones who can provide the throughput and the bandwidth necessary to share and to still download with no degradation to their service. And, with large (or even non-existent) bandwidth limits I'm sure, they can afford to share all they want and ultimately gain a high HEN. I see a lot of modem users being hurt the most because ultimately, it's hard to share and to download at the same time. Personally, if I were a modem user, I would be most concerned with finding and getting the files I needed and then disconnecting... I wouldn't want to worry about sharing my files with others because sharing while I'm downloading just hurts my downloading. Therefore I would probably never reach a high HEN. And then there are people in my situation. I may have a broadband DSL connection, but I also have a bandwidth limit on it. While I do share a lot, there are times when I may be downloading rather large files and my bandwidth limit doesn't allow me to get what I want and still upload to others. If that were the case, my HEN would probably be low and my chances of being disconnected from a host while downloading are increased dramatically and most possibly because of a T3 user who has a higher HEN wanting to download files from the same host I'm connected to. At any rate, this is just my 2 cents on the subject. Last edited by Smilin' Joe Fission; April 10th, 2002 at 02:14 PM. |

To cultiv8tor: Please notice that this approach doesn't block freeloaders. As somebody who doesn't share anything, you might have the bad luck that someone with a high HEN causes your downloads to break, but you still can download something - probably even more than in current network. To Smilin' Joe: Quote:
On the other hand, if there are any T1+ users out there who don't share much, this scheme will encourage them to raise their upload bandwidth limitator. With the current model of network these T1 users are more likely to leave Gnutella completely behind them and run off to FastTrak or some other. Quote:
BTW, to be able to download files with high reliability in this kind of network, you don't need an exceptinally high HEN of more than 128, you just need a HEN that's slightly above average. And with all those asynchronous connections out there, this average will probably not even be very high - about 40 or 50 perhaps. This can easily be achieved, even with a modem connection. You are speaking about the risk that some T3 user might come along and cause your downloads to stop. Hey, if there were that many T1 or T3 users out there that you'd actually have to worry about this, then the network wouldn't have a problem right now (and it definitely has...). With this scheme enabled, you would benefit a whole lot more from all those modem users start to actively share what they have than you would suffer from those few high bw users who might cause your downloads to stop from time to time. Remember, the goal of this whole thing is not to cause huge inequalities among Gnutella user, but to encourage freeloders to become sharers again. Currently, many people are freeloaders just because they see no benefit for themselves in actively sharing their files. Guido |

As for modem users being a benefit to me, like I said above, I prefer not to rely on modem users particularly because of the speed issue.... so added modem users probably wouldn't benefit me much at all (especially not for the rather large files I tend to download). Yes, their files eventually get distributed amongst others on the network, but like I said before, I haven't had any problems finding the files I've been looking for already... more of the same thing probably wouldn't help much at all. Quote:
Besides, there is one flaw that would have to be addressed in order for this system to work. And that is that a servent's HEN value is generated by the servent itself. This leaves the door open to someone who might want to guarantee their place in everyone's upload queue by modifying an open sourced servent to spoof their HEN values. If enough servents were to do this, the entire system could be rendered invalid and we'd be better off right back where we started. Of the few ways I've thought of to try to guarantee the HEN value is correct (and I will admit that I haven't thought of every possible option), every method could be spoofed in some manner. |
