But with the Internet now used for serious applications, thefocus point of a carrier hotel and exchange becomes much more mission critical. Ane because it is a focus point, it becomes much harder to haveredundancy in the buildings (to provide for disaster tolerance). So thenatural avenue is to strenghten/re-inforce your one central building.
It is not.The Internet can be mission critical. (Well, not really, but it's trying.) And for something mission critical, a single point, no matter how well reinforced, is not good enough.
The exchange point should _NOT_ be mission critical. As I explained multiple times in the thread, if that is your only vector, your design is broken. Period. Care to argue otherwise?
And if the IXP is not your only vector, if your redundancy is greater than any single building however deeply it is buried, then that IXP / building / vector is not mission critical. Treating it at such raises its price, which raises its barrier of entry, which lowers its utility.
Unless you think only NORAD-approved networks should peer? -- TTFN, patrick
