some light reading on complexity and the internet
by David Meyer 07 Nov '02

07 Nov '02

Many people have asked me to put the references from my complexity panel talk up somewhere. You can find some of the relevant literature on http://www.maoz.com/~dmm/complexity_and_the_internet I will try to keep this up to date, and please let me know if there are other documents that I should have here. Thanks, Dave

DNS timeline corrections
by Sean Donelan 06 Nov '02

06 Nov '02

I received some corrective input at the last Nanog meeting concerning some events on my DNS timeline (http://www.donelan.com/dnstimeline.html) from people who were there. I missed NIC.NORDU.NET as the first root name server outside the USA. Although I can't identify the precise date it was added to the root list. I took most of the dates from the namedroppers mailing list archives. Other corrective input is welcome. Also I noticed the change to the root server list on November 5 2002 was the first root server change since Dr. Postel died. Here is a copy of Dr. Postel's previous root server change announcement in August 1997 about bringing up M.Root-Servers.Net in Japan. http://ops.ietf.org/lists/namedroppers/namedroppers.199x/msg02852.html

High Processor Rates.

Yes, the sh proc cpu command is how you see the 5 second, 1 mintues & 5 minute CPU rates... But nothing shows here... Any other thoughts ?

Fw: Where is the edge of the Internet?
by alok 06 Nov '02

address (as per your scenario). You look up the destination in the routing table, and don't find it. So we look in RFC792 on page 5: If, according to the information in the gateway's routing tables, the network specified in the internet destination field of a datagram is unreachable, e.g., the distance to the network is infinity, the gateway may send a destination unreachable message to the internet source host of the datagram. In addition, in some networks, the gateway may be able to determine if the internet destination host is unreachable. Gateways in these networks may send destination unreachable messages to the source host when the destination host is unreachable. -------------> who does? the source is reachable.......via BGP.....its a valid internet address... And you send that to the bogus source address *HOW*? ------> how what??...it still isnt a problem for the actual traffic, the "source" network may exist on a BGP router as being advertised from another AS ......but not on the edge router from where it uplinks ......as was being discussed here Also, note the following: Another case is when a datagram must be fragmented to be forwarded by a gateway yet the Don't Fragment flag is on. In this case the gateway must discard the datagram and may return a destination unreachable message. Getting Path MTU Discovery to work is tough enough without some bozo network engineer assuming that assymetric paths with unroutable endpoint addresses will actually work. Yeah, sure - the destination *MIGHT* have a route back, but if *you* don't have a route back, things will break in subtle ways. ---------------> suggest u read the thread... we were : 1. discussing a ip spoofed attacks 2. the network/ip may exist on a BGP running router as being advertised from antoher AS/ differnet ISP.. its still present on the internet, .... but its a BGP route, not an IGP route...although that network uplinks from ur network...whats the problem? where does all this cause a problem? all ur edges will 0.0.0.0/0 to some bgp running router and the packet will get there.. ......there are enuf asymmetric networks, i can assure of of that... for one, you could simply try running a traceroute to some tracert sites from ur PC and a reverse trace from those servers to you.... ull find lots...

RE: High Processor Rates on Routers.

Try a show proc cpu to see what the router is doing if you really want to find out. -Jim -----Original Message----- From: internetguy205(a)hotmail.com [mailto:internetguy205@hotmail.com] Sent: Wednesday, November 06, 2002 8:22 AM To: nanog(a)merit.edu Cc: headguy(a)techies.com Subject: High Processor Rates on Routers. Ladies & Gentleman. Was wondering if it is common for processor rates on higher end Crisco boxes to race from 1 or 2 % show on the 5 second processor rate interval, to anywhere from 70 to 90 %, instanteously, then drop back down to 1 or 2 % after 10 seconds. The above mentioned scenario would happen every 30 seconds. The higher end boxes are very lightly loaded, with total traffic throughput of maybe 100 Meg, in some cases. Think that if these boxes are loaded more, to the point where the aggragated throughtput approaches a Gig, this will cause the processors to run at high levels constantly, driving the CPU rates indicators on the box for 1 & 5 minute intervals up to the values mentioned above. ( 70 to 90 % ). Higher end devices would be something like 7200, 7500, 12xxx series routers. This scenerio would be in a large ( very large network, atleast a tier 2 OR tier 1 provider )... possible rebutals to the fact that processors could race like mentioned above on lightly loaded devices of a higher end nature would be that BGP scanner is causing the problem, Telnet to the devices, show config when on the devices... So what happens to the processor rates when the devices are more heavily loaded ( 1 G aggragated throughput opposed to 100 Meg throughtput )? Will the devices work worrectly AND would a large internet be stable ? Is it also common for BGP Routing tables to be changing version every 1/2 second ? Same high end routers, lightly loaded, large Autonomous System. Thank-you for your time on this query.
