Actually I was thinking of a combination of 'order wires' with a combination of VSAT and in-band network conference bridges for backup. However several people of indicated that level of backup was too expensive. This problem isn't really unique to the Internet. I was looking at the backup communications network for SS7 providers and noticed a couple of major SS7 network providers don't give out their direct contact information even to other SS7 network operators anymore. They changed their listings in the emergency directory to general customer service numbers. -- Sean Donelan, Data Research Associates, Inc, St. Louis, MO Affiliation given for identification not representation

It was located in Building 6 on the 4th floor I think in E-aisle. Building 6 is the newer building behind the original collection of buildings at the corner of Naperville Rd. and Warrenville Rd. ihnp4 replaced ihnss. ihnss was one of the last large PDP 11/70s purchased at Indian Hill in Naperville in the late 1970s. I should know, I handled the SPA budget for it, and ordered it. It was a difficult decision not to buy a VAX at the time. We had to go with the proven PDP 11 because the VAX UNIX software was not stable enough when the orders were placed. We did research using ihnss. Phil Karn was new to Bell Labs and I encouraged him to take over ihnss when I left that location...I have not seen Phil since...when I returned to Indian Hill, ihnp4 was there...and Phil was gone...I assume that Phil somewhere along the line Phil convinced someone to convert it to a VAX...I suppose the increase in traffic was one of the reasons... I hope this helps to answer your questions about ihnp4 and also some of your questions about my association with AT&T... Jim Fleming Unir Corporation - http://www.unir.com

Zebra homepage?
by Alex Bligh 10 Jul '98

10 Jul '98

In Kunihiro Ishiguro's NANOG presentation it mentions a Zebra homepage of http://zebra.digital-magic.co.jp/ which appears to be unknown to DNS (at least to mine) as do all obvious permutations. Zebra also seems absent from their web page. Anyone know of a newer Zebra resource?

The cell tax is actually about 20%, based on the traces of the backbone IP traffic. Reason for this is the additional overhead imposed of partially filled cells.

Not sure what you are asking, but yes, the 32.100.0 /24 is a dial range IBM provides for Brazil...

Perhaps it might be helpful to read how some folks on the outside view the state of the Internet industry. http://www.ncs.gov/n5_hp/Information_Assurance/PSN-A97.htm Just for grins the President's National Security Telecommunications Advisory Comittee has established a working group on Internet outages. You all did get your invitiations, didn't you? http://www.ncs.gov/n5_hp/Information_Assurance/IO.htm A person asked my how I define 'tiny tykes.' Let me ask a hypothetical question. Do you think I could get 100 ISPs to sign up for this? Each contribute $25,000/annually to establish a out-of-band communication system between all the participating network operation centers. This may simply be a 'bat' phone with a really obnoxious ringer in the middle of their NOC connected via nationwide system which doesn't rely on IP, ATM, or SS7 to enable the NOCs coordinate/communicate when everything else goes to hell. In a previous life I knew this as a 'squawk box' which traders used worldwide. There have already been cases (plural, more than one) where you could not reach a provider's NOC because they obtained their 1-800 service from the same network provider supplying their network facilities, and the same event took out both. -- Sean Donelan, Data Research Associates, Inc, St. Louis, MO Affiliation given for identification not representation
