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 !
