FYI: - - - - - - - - Verizon Communications, Inc. v. Fed. Communications Comm'n Decided: 05/13/02 No. 00-511 Full text: http://laws.findlaw.com/us/000/00-511.html TELECOMMUNICATIONS (Federal Communications Commission's (FCC) Rules Under Telecommunications Act of 1996 Valid) The United States Supreme Court held 8-0 (opinion by Souter; concurrence by Breyer; dissent in part by Breyer; O'Connor took no part in decision) that the FCC can require state commissions to set the rates charged by incumbents for leased elements on a forward-looking basis untied to the incumbents' investment and can also require the combination of elements. The Telecommunications Act of 1996 (Act) was intended to eliminate the monopolies enjoyed by the inheritors of AT&T's local franchises. The Act entitles the new entrants to lease elements of the incumbent carriers' local-exchange networks, and directs the FCC to prescribe methods for state utility commissions to use in setting rates for the sharing of those elements. The FCC promulgated rules that created pricing provisions, based on a forward-looking pricing methodology, and required incumbent local telephone companies to combine certain previously uncombined network-elements when a new entrant requests the combination. Incumbent carriers and state commissions challenged the FCC's rules. The Court of Appeals for the Eighth Circuit invalidated both of these rules, holding that the Act required that rates be based on the actual, not hypothetical, cost of providing the network element and that there was no authority for the FCC to require the combination of elements. The United States Supreme Court reversed, stating that the FCC's rules were reasonable interpretations of the Act and the incumbents did not meet their burden of showing unreasonableness to defeat the deference due the FCC.

actually gre fragmentation itself has nothing to do w/df bit. you either leave the tunnel with default mtu (and use ip fragmentation - of course depending on df) or you may cause it fragmenting packets and resembling them at the tunnel end. on cisco boxes this is triggered by using larger 'ip mtu' (not interface mtu) value. there are some memory and cpu drawbacks due to defragmentation (a hold queue for fragments until they all arive etc.) -- Tomas Daniska systems engineer Tronet Computer Networks Plynarenska 5, 829 75 Bratislava, Slovakia tel: +421 2 58224111, fax: +421 2 58224199 A transistor protected by a fast-acting fuse will protect the fuse by blowing first. > -----Original Message----- > From: Forrest W.

5.2 Earthquake in Northern California
by Sameer R. Manek 14 May '02

14 May '02

We just had a 5.2 magnitude earthquake at 10pm, it was centered SW of Gilroy, CA. Cingular's network was peaked for a few minutes after the call, presumably as everyone called friends/family. No reports of phone/power outages yet. Sameer ------------------------------------------------------------------------- Sameer R.

I can understand your lack of belief. Imagine my surprise when I got 9 emails in response to my question and 15 questions about how to replicate my sig. LOL!!! I've been laughing about that all day. Who says engineers can't have a sense of humor. If you met me somewhere besides work, or even at work, you probably wouldn't think I was an engineer. But I am. -----Original Message----- From: Rik Thomas [mailto:rikt@smartbackups.com] Sent: Monday, May 13, 2002 8:08 PM To: Heath_Dieckert(a)exchange.dell.com; nanog(a)merit.edu Subject: Re: DirecPC Engineering Contact And I can't believe an engineer would know any better than to post that signature.

BGP and aggregation
by Ralph Doncaster 13 May '02

13 May '02

I have transit in 2 cities. I have a circuit connecting the 2 cities as well. So far I've been using non-contiguous IPs, so there's been no opportunity for aggregation. Having just received my /20 from ARIN, I'm trying to plan my network. Lets say I split the /20 into 2 /21's, one for each city. I'd like to announce the aggregate /20 instead of 2 /21's, as long as the circuit connecting the 2 cities is working. If the circuit goes down I want each city to announce the local /21. Is this possible? (using either a Cisco router or Zebra) Ralph Doncaster principal, IStop.com div. of Doncaster Consulting Inc.

Certain websites (mainly financial) send large packets and set DF. This probably works around some security issue but the result was that these SSL servers couldn't reach clients over the GRE. -- Roger Marquis Roble Systems Consulting http://www.roble.com/

Does anybody on the list work for DirecPC or have an engineering contact at directPC. I can't believe they are selling non-routable addresses as an ISP to the general public. Please reply offline. Heath Dieckert Network Engineer Dell US Internetworking Systems 512.723.5026
