ATM to the desktop never took off, whats wrong with Ethernet over ATM ? With devices such as IADS, it allows for easy differentiation of traffic. Now you can cary voice and data over the same physical link without worry. [..]
Ever tried it without that? I have done quite a bit of less than scientific testing of VoIP over a QoS-less infrastructures. Small VoIP packets seem to have little trouble squeezing thru and it works actually pretty well. That's without ATM QoS crap on a broadband connection.
I have to concede here. We were able to run the VOIP traffic using UBR, out network not being saturated, this may have helped, on a busy network, a lot of problems could have arrisen. What is nice, is that QOS is easy to enable in ATM. There are many reasons that ATM has not taken off, from a CLEC perspective, I believe it to be the superior technology. I would much rather have a 10 Mbps Ethernet feed from a company like Cogent but those links do not compare in pricing with DSL.
