Anyone got numbers on peering vs transit?
by Aleksi Suhonen 05 May '06

05 May '06

Hello, I wonder if anyone has done any estimates on how many percent of the Internet traffic: A) does not pass a peering relationship (i.e. is AS internal or passes through transit connections only) B) passes a public peering relationship C) passes a private peering relationship I know this is fairly impossible to estimate globally, so even any local or network specific research is appreciated. -- Aleksi Suhonen / Axu TM Oy Internetworking Consulting Cellular: +358 45 670 2048 World Wide Web: www.axu.fi

Usage-based billing
by ravi 03 May '06

03 May '06

Hello all, read through the charter/guidelines and I believe (hopefully correctly!) that my questions are not out of place. I am looking for advice on usage based billing solutions. I am interested both in the data collector / collection part and the billing part, and would ideally want separation between these two parts (so that the collector could be used with alternate billing systems, including in-house ones). Any suggestions on NetFlow/SFlow use? Tools (apart from Cflowd and flow-tools)? Commercial solutions? What are the general concerns with using NetFlow for billing? I understand I am asking a question that is very wide in scope, but would appreciate even generic pointers in response. Also, Juniper provides a set of alternate Network Accounting Solutions as their "response" to Flow-based accounting. Any pointers to comparison of their solution with others? Experiences? Implementation documents? Thank you, --ravi

RE: Strange network problem accessing Ebay and versiontracker websites

We don't use PPOE. Our network setup is DSL Modem -->ATM-->BLC (Occam)-->IP--->Router--->Transit provider. Basically we turn on the service and it's always running. We don't require any authentication or do any subscriber management on our users. I will start looking into the MTU issue though.

It sounds like that is a possibility. Are the DSL users being served by PPPoE? Setting the IP MTU on your PPPoE access template, depending on whose gear you're using to provide the servide provider end of your DSL services, to 1492 may help. jms

Strange network problem accessing Ebay and versiontracker websites
by Shane Owens 03 May '06

03 May '06

All, I know this probably isn't the best forum for this question but I'd like to rule out a network problem before I tell a customer he has a PC problem. I run a small CLEC network that is single homed to BTN for transit. I have 3 sites all interconnected via DS3's and provide DSL services from each site. From anywhere on my network we have problem with Ebay and versiontracker.com but only on certain browsers. IE on a windows machine can access these sites without any problems, but Firefox on the same machine cannot open the websites (Ebay can be opened with addblocking software installed). On a Mac the only browser that works for these sites is Opera. With this knowledge I would say it is something with the coding on the website, but if I take the same machine and connect it to another network other than mine (Verizon, SBC and local municipal wifi have been tested) everything works fine. Can anyone give me any suggestions as to what routes to take to troubleshoot this? Logic tell me that is I have reach ability and one browser work but another doesn't it's a software problem with either the browser or the site, but being able to take the same machine to another network and have it work points to a whole different problem. Could this be a MTU issue? Shane Owens DNA Communications Inc 601 1st Ave Rochelle, IL 61068 work (815)562-4290 ext 201 mobile (815)793-3822

We have a feedback loop with them on a netblock we moved off of about 24 months ago; I've emailed their postmaster at least 12 times with no response and no change. I've called and they refuse to talk and say I must email or use the form on the postmaster site to be removed; no effect. David

Interesting to notice someone (perhaps from this list?) has removed Cogent from the T1 list. They did however leave http://en.wikipedia.org/wiki/Cogent alone. -Scott -----Original Message----- From: owner-nanog(a)merit.edu [mailto:owner-nanog@merit.edu] On Behalf Of Martin Hannigan Sent: Wednesday, May 03, 2006 10:07 AM To: Richard A Steenbergen; Robert Sherrard Cc: nanog list Subject: Re: Tier 2 - Lease?
