Paul -- you know, i was advoicating cacheing for a long time. But the problem with USENET is not in transmission technology. Fundamentally, it is inability to keep the S/N ratio high enough by keeping away trash generators. If someone posts an article, it has to show up in some kind of directory. Otherwise people won't be able to find and to pull it. USENET-style directories (listing subject lines, timestamp, and originator's pseudonym) do not carry enough information to detect spam. The net result - even if someone's using spam filters at his end, he still has to pull all articles. No gain whatsoever. (Pruning newsgroup distribution trees is another issue altogether - it can be done with little modification to the existing software). What USENET needs is a distributed system for collection of per-article and per-sender ratings, and for filtration based on those ratings. That would be useful for other applications, as well :) --vadim

Re: Reducing Usenet Bandwidth
by Vadim Antonov 11 Feb '02

USENET is by its nature a commons facility for sharing rivalrous resources (e.g. bandwidth and storage capacity). Elementary reasoning (if anyone's interested, Lawrence Lessig's "The Future of Ideas" contains as detailed discussion as anyone can bear :) leads to the conclusion that lacking usage control mechanisms such commons are doomed to disintegrate. No exceptions were found so far. (Such control mechanisms do not have to be market-based to be effective and successful; public policy or code may embed usage controls as well - TCP's cooperative congestion control is an excellent example). When the Internet was small, the personal reputation was strong enough limiter to abuse of shared resources. It only works when community is smallish and elitary. This is clearly no longer the case. In other words - USENET cannot be fixed with technological improvements as long as the root problem (admission control) is not solved. Improving transmission or storage systems would only let spammers to send more spam for free. Therefore, i'd say it is time to declare USENET defunct. It was fun while it lasted. --vadim PS. Talking about commons... A lot of network and computing resources are quite under-utilized. Many owners of those resources would be quite willing to donate underused capacity to the community - providing that such donation will not have any noticeable negative impact on resources' performance for primary functions. While most modern OS-es have mostly adequate prioritization mechanisms, a lot of would-be donors are turned out by the effective inability to protect their primary network capacity. Therefore, i would like to ask ISPs to be civic-minded and standartize on an IP TOS for "community" traffic, giving normal IP traffic an absolute queueing and drop-policy preference over packets with community TOS. Correspondingly, though most backbone (and some access) IP routing equipment already has everything needed to implement community TOS, they could be similarly civic-minded by making such preference turned on by default and by improving per-TOS utilization data collection, so NMS-es won't cry wolf seeing links being highly utilized by low-priority traffic. Another area which needs improvement is making L2 switches similarly aware of community TOS in IP packets.

If the USENET distribution system passed pointers to Just to chime in, the idea of passing pointers around has come up in several different versions over the last so many years and combined with pre-fetching/caching seems like a very good idea; it's a pity that no one has really tried it given that many of the tools already exist (disclaimer: I've been dabbling with writing something using existing protocols on and off for some time). So far, and this was inspired by the loss of a clariNet newsfeed, I've written a silly little personal nntp server based on an SQL back-end that collects RSS pointers to website "articles". The server stores the "pointers" (URLs) and retrieves the article directly from the remote webserver (or local http cache) on demand (currently spits out html, ugh). The header info (overview) is composed of the RSS data (unfortunately quite sparse in most cases) and the "headline" fetcher script builds a "score" for each article based on my predefined criteria. I've found at least one mailing list archive that produces RSS files for each mailing list that can be simliarly used to populate a "newsgroup". So mailing lists provide a simple way of creating a "publishing" method other than a website. In all these cases, "replying" to a message is a bit involved, but not impossible. So, as far as I can tell, all the tools exist to implement a new set of newsgroups based on existing protocols that don't involve the massive bit movement of Usenet however preserve the highly efficient news reading mechanisms of news readers. Anyone have a sample, open-source, robust NNTP server implemented in Java or perl that needs a SQL backend and article population mechanism? Adi
