 | View Full Version : Dcjn? infinity7 01-04-2003, 08:55 PM How is DCJN for pings and stability? I hear it is 20 something % cogent, then the rest is all NAC peers? So if it does have some cogent in it, are any of the pings affected (with the whole AOL cutting cogent's peering) Rewdog 01-04-2003, 09:00 PM I'm also interested in this. I was told they cut out the top 6 carriers and replaced those with a cogent line, along with the 70 other providers. Those 6 top carriers carry most of the internet... jayglate 01-04-2003, 09:07 PM Despite cogents aol peering mess up.. DCJN has I believe a GigE to AOL soon to be dual OC12's to them. So don't worry about AOL ;) LavaHOST 01-04-2003, 09:09 PM What exactly is premium NAC bandwidth in comparison to DCJN? jayglate 01-04-2003, 09:19 PM 70 to 80% of NAC's traffic comes from peers. The difference between NAC Premium and DCJN is what the remaining 20-30% is wheather is is cogent or williams, att, uunet above.net and genuity, amoungst others. LavaHOST 01-04-2003, 09:33 PM Does premium NAC go through cogent or WCG at any times or is that left for DCJN? jayglate 01-04-2003, 09:47 PM Only if it is the fastest route.

LavaHOST 01-04-2003, 09:52 PM Is it possible to tell if someone is DCJN or Premium NAC jayglate 01-04-2003, 09:59 PM Not very easily, no.

I wonder what is stopping hosts from lying and just saying it is pure NAC when it's DCJN, aside from the fact that they are just being honest (which is good). mdrussell 01-05-2003, 05:45 AM It used to be pretty easy to tell from a traceroute. Has that changed Jay? zerphyte 01-05-2003, 05:46 AM no it hasn't changed. if it goes though aggr1.nyc.dcjn.net its dcjn. if it doesn't its not dcjn. netdude 01-05-2003, 08:09 AM so... i lay this question for you guys that work with nac... why would someone want to peer nac.net ? whats their benefit... ?? isn't their b/w usage as one-sided as cogent's...?? so why peer with nac but not cogent? lol... (question aimed primarily at aol/nac peer)... netdude 01-05-2003, 08:13 AM o... hadn't noticed the end user base (dsl n stuff)... heh... ok, thats reason enough i guess... :D zerphyte 01-05-2003, 08:14 AM If say ispa has alot of traffic that goes to nac and nac has alot of traffic that goes to ispa, its just not logical to pay for that bandwidth when you can just peer for free. netdude 01-05-2003, 08:18 AM but putting that into the context of say cogent... who has very one-sided traffic... isp A (cogent) ... and isp B (aol for example; i'm gonna laugh about this 'till the day i die)... well... with isp A's traffic being as one sided as it is, it isn't a fair trade... so why would isp B put up with it? (answer: they didn't... LOL) mdrussell 01-05-2003, 08:22 AM But, as you mentioned, NAC's traffic isn't especially one sided - why put it into the context of Cogent? netdude 01-05-2003, 08:26 AM sorry... was refering to the peering situation as noted out in zephyte's last post... |
