Sometimes it can give a hint. However, if the ISPs are following the ³interface name² convention, youıll get something like P3-1-2, which just tells you its Packet Over SONET. That can mean anything from OC-3 to OC-192. ³ge² could mean 10 gige :)
The "2488M" from glbx is nice, but not too common. It would be so nice if this were standardized between all providers. But naming conventions are really political - they sometimes provoke huge fights even within providers. -- Daniel Golding Network and Telecommunications Strategies Burton Group On 7/1/04 8:25 PM, "Cody Lerum" <[EMAIL PROTECTED]> wrote: > DNS can sometimes give you a hint > > [my nets snipped] > 4 t3-1-2-0.ar2.SEA1.gblx.net (64.211.206.113) 20.436 ms 18.309 ms 17.605 > ms <------------DS3 > 5 so1-0-0-2488M.ar4.SEA1.gblx.net (67.17.71.210) 17.607 ms 16.982 ms > 16.971 ms <-----OC-48 > 6 p3-3.IR1.Seattle-WA.us.xo.net (206.111.7.5) 17.864 ms 19.491 ms 17.181 > ms > 7 p5-1-0-3.RAR1.Seattle-WA.us.xo.net (65.106.0.197) 17.723 ms 17.632 ms > 19.045 ms > 8 65.106.0.50 (65.106.0.50) 38.133 ms 39.197 ms 49.961 ms MPLS > Label=101549 CoS=0 TTL=1 S=1 > 9 p0-0-0d0.RAR1.SanJose-CA.us.xo.net (65.106.1.61) 37.669 ms 38.572 ms > 36.517 ms > 10 p7-0.DCR1.DC-SanJose-CA.us.xo.net (65.106.2.146) 37.830 ms 36.524 ms > 37.743 ms > 11 ge1-1.CDR2.DC-SanJose-CA.us.xo.net (209.220.168.10) 38.428 ms 38.050 ms > 37.179 ms <-----Gig Ethernet > 12 205.158.6.100.ptr.us.xo.net (205.158.6.100) 40.179 ms 39.784 ms 39.444 > ms > 13 x218.cd9e6c.sj.concentric.net (205.158.108.218) 39.188 ms 39.723 ms > 39.895 ms > > However MPLS hidden hops may hide internal paths, and any connection may be > limited to slower than its line rate, and dns entries may be old.... > > It's not publicly available at one source that I'm aware of, and if there is > they don't have my info. > > -C > > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Erik > Amundson > Sent: Thursday, July 01, 2004 6:10 PM > To: [EMAIL PROTECTED] > Cc: [EMAIL PROTECTED] > Subject: Peering point speed publicly available? > > NANOG, > > I have a question regarding information on my ISPıs peering relationships. > Are the speeds of some or all peering relationships public knowledge, and if > so, where can I find this?
