As we know only the telephone network suffered more whereas internet remained stable. Their might have been some problems in the access because of the flash crowd problem. A particular slide from the nanog 23 presentation http://www.nanog.org/mtg-0110/ppt/misconfig/sld010.htm shows the behaviour on 9/11. Just observe closely the slide in the above link. It covers a period from a period from 8/1 to 9/26 and there was variation of 40-60 prefixes (between aug and september), except on 9/11 (there was 100 changes.) Only 0.1% of the route table was lost. BGP was more unstable during code red propagation(http://www.renesys.com/projects/bgp_instability/.) A quick peek into both the graphs will make one thing clear: *BGP is robust enough to withstand any extreme congestion.* But the question is: what can be an effective solution for access congestion on days like 9/11? __________________________________________________ Do You Yahoo!?
