The biggest worry to me is that depite all the promises offered and realities
measured in the labs on all this MPLS, IP switching etc etc -- Internet
protocol cannot provide the QoS for voice and video multicasting with 5 Nines
reliability. IETF and Carrier Class 5 Nines reliability in a bulletproof
manner are like 2 cities still poles apart. Efficiency feathers went to IP-
cannot we be a little more honest and praise the Optical media and the Fibres
since even POS needs layer 1 optical PHYs.
Traffic management is another name of 99.99999% reliabiity at the end of the
day !
Just a comment , we are comparing apples with Oranges !

Yes, that's its problem.
From issue 10 of "New Carrier" (http://www.totaltele.com/newcarrier";, p 22:
... the past several years' debates over the relative technical
merits of [the] Internet Protocol versus other network technologies
like ATM, often missed the point. IP and its associated technologies
haven't taken over because they produce a brilliantly efficient network,
but because they together seem capable of creating a dynamic
openness for the network economy; this is because of, and not
despite, a simplicity and a lack of carrier-style attributes.
