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? (web based preferably rather than mailing list - or a mailing list archive URL) -- Alex Bligh GX Networks (formerly Xara Networks)

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... Please take this off-line (off NANOG) and respond to me (or noc(a)ibm.net) directly with any questions you have.

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

The Cidr Report
by Tony Bates 10 Jul '98

10 Jul '98

This is an auto-generated mail on Fri Jul 10 12:00:01 PDT 1998 It is not checked before it leaves my workstation. However, hopefully you will find this report interesting and will take the time to look through this to see if you can improve the amount of aggregation you perform. The report is split into sections: 0) General Status List the route table history for the last week, list any possibly bogus routes seen and give some status on ASes. 1) Gains by aggregating at the origin AS level This lists the "Top 30" players who if they decided to aggregate their announced classful prefixes at the origin AS level could make a significant difference in the reduction of the current size of the Internet routing table. This calculation does not take into account the inclusion of holes when forming an aggregate so it is possible even larger reduction should be possible. 2) Weekly Delta A summary of the last weeks changes in terms of withdrawn and added routes. Please note that this is only a snapshot but does give some indication of ASes participating in CIDR. Clearly, it is generally a good thing to see a large amont of withdrawls. 3) Interesting aggregates Interesting here means not an aggregate made as a set of classful routes. Thanks to xara.net for giving me access to their routing tables once a day. Please send any comments about this report directly to me.
