There are just more alternatives to use the SONET/SDH infrastructure. Of course there is no reason to have anything too complicated like ATM cell-slicing on a point-to-point SDH link between two routers, but there is also no reason to force everything to go through a router, if ATM can do guaranteed voice QOS over the same SDH cloud and bypass several routers, that can almost do it. There will be no single technology. What's going to be the net for the next generation multimedia cell phones ? They are supposed to have 2Mbit/s data rate and ip networking, but also normal telephony. VesA |
