OT: Advice needed on dialup problems - TCP corruption? (windows users)
by Jeffrey Wheat 10 Jul '02

10 Jul '02

Good day everyone, I am seeing a strange problem on my network lately after adding a new terminal server, a Lucent MAX TNT with madd modems in it. The symptoms are that users can connect, they can ping and traceroute without any trouble. Anything that is TCP based however is failing. In some cases, disabling software compression fixes the problem for a short period of time. I am not experienced enough with the MAX TNT units to know how to debug the TCP packets as they come from the user. I am running 10.0.0 TAOS on the unit. Can anyone please offer some advice or suggestions? I am too young to go bald :) Cheers, Jeffrey --- Outgoing mail is certified Virus Free.

Mail Software Used by ISPs
by Crist J. Clark 10 Jul '02

10 Jul '02

I am interested in information on what software small, medium, and large ISPs use for email services. When I refer to "email services" I mean SMTP, POP, IMAP, web mail interfaces, and the back-end administrative tools. Do many/most ISPs use big, expensive enterprise tools for this? Piece their own systems together using various commerical/free tools for the different parts? Or do they roll their own almost top to bottom? I have experience doing email for small and medium corporate sites (in the 100's of internal users), but the particular project I am working on is for customers, not internal users, and could quickly balloon from the few dozen on the current demonstration system to thousands. Any firsthand info or pointers to more information would be greatly appreciated. -- Crist J. Clark | cjclark(a)alum.mit.edu | cjclark(a)jhu.edu http://people.freebsd.org/~cjc/ | cjc(a)freebsd.org

I agree, but as a regional player most large players won't peer with us anyway from my discussions with them.

I'm not sure if there is a better list for this but I know this reaches some of the key audience members:). Could anyone interested who can offer transit at the E-xchange facility at 200 Paul in SF contact me privately. I'm looking for some transit for a new project. Thanks Scott

Out of those options I think Big Brother probably comes closest and it was on the checklist to see if it is useable. I should probably have been more specific. What we are looking for is an automated checking system that can send a text message if a problem is found. It doesn't have to be all in one as I believe we currently have an email-sms gateway available to us.

RE: multicast (was Re: Readiness for IPV6)
by David Sinn 10 Jul '02

10 Jul '02

There is also a "cart and horse" issue here: Where is the pervasive content? Most content providers don't want multicast because it breaks their billing model. They can't tell how many viewers they have at a given moment, what the average viewing time is, or any of the other things that unicast allows them to determine and more importantly bill their advertisers for. There is no Nielsen's Ratings for multicast so that advertisers could get a feel for how many eyeballs they are going to hit. Then add in the latest from Congress with regard to streaming audio over the net, and you have a source payment issue making you not want to go down the multicast path. (Leaving Congress living up to their name as being opposite of progress.) Multicast is a great technology. It just is stuck looking for a problem to solve that doesn't create even more problems.

Speaking from a provider who used to run multicast, and now doesn't: Customers don't want it. I can count our customer requests for multicast on both hands for the last two years. Of those, only one thought it was important, the rest were just playing with it. In fact, pretty much the only place we see it anymore is on RFP's from educational groups. My own view is that customers don't want it, because end users don't have it. Dial up users will probably never get multicast. So that leaves Cable Companies (good luck for them to do something intelligent) or DSL providers (perhaps they might) to make it happen. If a few million end users could just 'get it', then people running streaming services would be beating on backbone providers to carry it around. There is also a payment problem. If a unicast bit enters your network, you can be assured it takes one path to the destination. When a multicast bit enters your network, it could take one path, or it could take 50 paths through your network. The latter does cost the ISP more. This also makes peering an issue, as many people use ratio. If there was a significant amount of multicast traffic, hosting ISP's would send end-user ISP's one small stream that they would then replicate. That would pretty much make the ratio completely opposite of what it is today, due to unicast streaming. I'll be the first to jump on the multicast bandwagon, but I don't work for an eyeball provider. The first adopters need to be DSL and cable modem providers, to the end user, on by default. Then we can go somewhere. -- Leo Bicknell - bicknell(a)ufp.org - CCIE 3440 PGP keys at http://www.ufp.org/~bicknell/ Read TMBG List - tmbg-list-request(a)tmbg.org, www.tmbg.org
