Risk of Internet collapse grows

Its difficult to tell what the authors have discovered since the paper won't be published for four months. From the press release I notice some language which would indicate it may have the same issues other Internet models have predicting the impact of physical disruptions. Q: What's the difference between airline traffic and highway traffic during a snow storm in Chicago? A: A snowstorm in Chicago doesn't have much of an impact on highway traffic through Dallas. But a snowstorm in Chicago does impact air traffic in Dallas. Air traffic in the US is a tightly coupled system. Air traffic is coordinated nationally, and passengers must make connections at fixed points which are difficult to change. Its difficult to get on a different plane heading in the general direction of your destination. Automotive traffic is loosly coupled. Auto traffic is locally controlled and cars may be individually re-routed towards its destination at many different points. Which analogy is closer to what happens to the Internet? Air traffic or highway traffic? Or maybe Internet traffic is like Internet traffic.

Yah, the abstract indicates what most of us already know. Good coverage and redundancy options in urban areas; less so for rural areas. Why should this shock anyone? Imminent death of the 'net is *not predicted ;-) Eliot
Actually, I think we should all be more concerned that in most metro cities, there is always 1 major mega CO. In the CO, not only do the RBOCs have tremendous critical technology aggregated there, but almost every telcom provider also locates key technology and network there. Knocking out that facility would critically damage both voice and data in that region. It is also a critical interconnect point btw operators since they all happen to be there. Does anyone still remember that event in Atlanta where worldcom lost power in one of their facilities after a storm knocked out power, and the generator had contaminated fuel (circa 1997). That had a major affect on communications and we are not even talking RBOC CO. At 5:46 -0800 11/27/02, Eliot Lear wrote:

Doesn't that argue for a more mesh-like architecture?

From a resiliency standpoint, yes. Economics, and to a certain indirect sense capacity concerns, favor aggregation over route

How much of this research is based on marketing maps on the ISPs' web sites, versus actual maps of the networks in question? Most "tier 1" ISPs won't even let their vendors see the latter. S

last year we *measured* isp maps as part of a research project called rocketfuel and found that the marketing maps can differ significantly from the real ones quite a bit because of lack-of-detail, outdated-ness, or optimistic-projections. a paper describing the methodology and the maps themselves can be found off: http://www.cs.washington.edu/research/networking/rocketfuel/ -- ratul

and, aside from reversing the meaning of a comment you attribute to me, i heartily recommend this paper. randy
