Comcast contact
by Vinny Abello 11 Apr '03

11 Apr '03

Can some network engineer/admin from Comcast contact me off list? Or if anyone knows how to get in touch with someone at Comcast that is an network engineer or admin for their network... There seems to be less than the usual amount of contact information available for their network people than most ISP's unless I'm just looking in the wrong places which may be entirely possible.

NANOG/ARIN in Chicago
by Susan Harris 11 Apr '03

11 Apr '03

Greetings everyone - NANOG and ARIN are very happy to announce our 2nd back-to-back meetings, NANOG29 and ARIN XII: ----------------------------------- The 2003 Joint NANOG/ARIN Meetings ----------------------------------- October 19 - 24, 2003 Chicago, Illinois ----------------------------------- ARIN is the American Registry for Internet Numbers, www.arin.net. If you've never attended an ARIN meeting, take this opportunity to influence address assignment policy for N. America, a portion of the Caribbean, and sub-equatorial Africa. The striking thing about ARIN meetings is who's in front of the room -- for the most part it's users on the Advisory Council or Board of Trustees, not the ARIN staff. The community has the main voice in ARIN decision-making -- your input plays a huge role in policies for v4 and v6 address requests, allocations, assignments, abuse, and privacy. NANOG will meet Sunday - Tuesday, Oct. 19-21, and ARIN Wednesday - Friday, Oct. 22-24. Looking forward to seeing you then!

During the Civil War, it was common for Union politicians to label anything they didn't like as "rebellious" or "treasonous." In the 20th century, the word was "nazi," or, especially the McCarthy era, "communist." Now it is "terrorist." In any case, it is inaccurate, manipulative, and childish, and does not belong on a professional mailing list. Call me a treasonous communist nazi terrorist, but do it off list, please. -Dave On 4/11/2003 at 11:51:31 -0500, Daniel Golding said: > > This is a joke, right?

dual router vs. single "reliable" router
by David Barak 11 Apr '03

11 Apr '03

Okay, I'll bite... the mentioned file, http://www.nspllc.com/New%20Pages/Reliable%20IP%20Nodes.pdf seems to be fluff to me. There are many assumptions and statements about reliability, but the methodology of how the numbers were reached is not present. If one assumes that one has a router which fails very rarely, this would dramatically affect network design. However, this is an assumption, not a conclusion. The assumption of the paper is that the Alcatel box has ultra-low failure rates, while the Juniper and Cisco boxen have relatively high failure rates. Personally, before I let something like this influence my buying/design decisions, I'd want to see some serious raw data... ===== David Barak -fully RFC 1925 compliant- __________________________________________________ Do you Yahoo!?

I would hope you do get someone who speaks English, given that it's the official language there. :) Of course, the accent of some Singaporeans (naming no-one!) can be quite...erm...challenging. BB

[snip] Tear this page out of the notebook and highlight it. Even a small shop that "can't afford" a testbed or lab can dramatically reduce problems with formal procedures borrowed from software engineering.
