Hi ftth. I just wanted to say that upon re-reading my reply to you in #7016 it might seem that I was being condescending in some ways. I wasn't. I don't mean to sound overly pedantic or authoritarian, but I've received some E-mails and PMs recently citing the value of the thread, accompanied occasionally by a request to be more accommodating to the lay folk who stop by to *lurk 'n' learn.* That explains some of the instances in my previous several posts where I've used parenthetical explanations for acronyms and spent a little more time in clarifying and explaining issues than I normally would if we were talking it out over the phone. We've been through this before, as you know, and it usually wears off after a while and then it's business as usual. If that occurs, lurkers, just send a PM to bring it to our attention. A nudge sometimes goes a long way. Maybe it's time to attach a list of glossaries to the front page of this thread, as was someone started doing on the front page of the Last Mile Technologies forum thread. See the bottom of the introductory post: Subject 4754 Let's discuss this further. Some means of assigning board space for tutorials and glossaries, such as the lists of stocks that fall under some thread banners, is probably a good idea. As in this list of symbols organized in the Gorilla and King Portfolio candidates - Moderated thread, beneath the banner opener: Subject 54354 Your thoughts, as coming from the moderator of this thread, are welcome ;) FAC frank@fttx.org

The following is a discussion (message no. 4310 from this board) that I referenced yesterday in my message no. 7016, uplinked, above. In this instance we examine a November 2001 situation that centers on the ongoing plight of a small Canadian cable operator who is offering Internet services to cable modem customers, and the advice he's receiving from the manager of a larger ISP who is showing him the ropes. After considerable frustration over not being able to obtain the upstream (WAN) bandwidth that he needs, the smaller cable op asks: -------- >The dsl is no better as we share the same line to the south..the problem is >that there is only so much bandwidth for everyone to use. Is there satellite >bandwidth out there that is $3000 or less per 1 Mb? ------ And the advice that is offered: Sat bandwidth will introduce a 450+ms latency issue. You REALLY need to find out what type(s) of traffic is most used... if their cache'able then cache them. If not... find out who's doing the most traffic.. It's the old 80/20 rule... 80% of your bandwidth is used by 20% of your customers.. If you have a guy doing 5 gig of FTP or NNTP or ANYTHING traffic... kick them off for overusage of your network. Put up firewalls.. kill programs like Napster, KuZdU (or whatever it is), and the rest of the high bandwidth usage programs... ban the ports both in and out at the firewall before it ever enters the network... Kill all inbound packets to your customers below 1024.. then they can't run common things such as DNS/FTP/HTTP etc servers on common ports. The biggest thing is you MUST be able to tell what your traffic patterns are... You should be able to say something like "65% of my traffic is HTTP/HTTPS, 25% is FTP, 5% e-mail, and 5% misc traffic" If it's HTTP traffic that's getting you... then get a SAT connection and redirect your HTTP traffic to a caching proxy server that gets it's feed from the Sat. If it's streaming Multicastable audio/video/etc... then get a Multicast connection from MulticastISP (or someone like them) Ftp... find out who's doing it.. and kick them off your network. I had a guy that was eating almost 10 GB a day in NNTP (news feed) by himself... the rest of the network's traffic didn't even come to what this guy was doing in just NNTP traffic... I sent him a letter and told him that he had to quit the traffic... that didn't work.. so I blocked the port (port 119) so that he could no longer do it.. The point is that I did piss him off on that, but I got him to realize that he's eating up a few K a month in bandwidth that he's paying 50 bucks a month for.... he went to a competitor of mine... and got kicked off their network for the same thing. You can't be a nice guy to the customers all the time.. the days of the free rides, free websites.. free e-mail and everything else are comming to an end.. ---end Message 16648057 ---------------- FAC frank@fttx.org
