Can you get some up time of lets say 50 CISCO routers for the past 1 year (leave the scheduled maintenance) from MCI backbone and report those numbers. By the same token, get the up time of some 50 TDM switches from 50 busy cities in US and provide the data. I agree with forrester report. Packet switched networks have way to go when compared to circuit switched networks. Convergence will happen, but lot of them is hype right now. All compression algorithms are meaningless (practically) when we have DWDM available. If you do a digitization of voice calls at 64Kbps or 8KHZ sample it would yield 6400 bytes/sec in 1 direction. For 100 million phone calls, it would be 640 billion bytes/sec. With DWDM, one could carry this very easily like NT's chairman mentioned. It is regular file transfer, HTML traffic like what I am generating now which will interfere with voice traffic. Today, Nobody has a system which can scale to 100 million phones call along with data traffic. Imagine an earthquake like 1989 quake in SFO and you get 160 million phone calls into the city for the entire day with each one holding onto the phone for 15 minutes. Can CISCO solve this problem (provide a switch/router/convergence BS) in 1 year from now at the same time sending data traffic across.?.
