re: Nortel Puts On a Brave Face
Does anybody else have stats that talk to the issue of circuit vs packet traffic? I thought we were already up to 50/50, but what do I know :-)

I am very interested in reading up to date studies regarding this topic.

re: Nortel Puts On a Brave Face That 50/50 figure was for data vs voice, not data vs circuit.
Basically, the network is still overwhelmingly circuit-switched (ie, DS-0/1/3), but more than 50% of these circuits contain data.

As for how much of the network is non-circuit-switched, I think this is a tougher question to answer. First, do you consider ATM a form of circuit switching? If not, then the figure's got to be fairly high (but remember, a lot of this ATM traffic is circuit-emulated DS1/3s). If not, then the figure is very low, because only a few networks are really based on OC-48c/192c MPLS packet pipes. And then I have no idea if a network like Quest's (which supposedly has a lot of MPLS) is running circuit emulated traffic, or are these truly packetized services?

Anyone know?
