Yes you are right, they double the full-duplex bandwidth

http://www.lightreading.com/document.asp?doc_id=188948&; With the upgrade, Cisco can run 140 Gbit/s per slot, with switching capacity of 4.48 Tbit/s per chassis. (The latter figure is doubled to count ingoing and outgoing traffic at the same time, as the industry tends to do.)

If you don't mind me asking what did you work on (juniper, ALU, etc.), and what exactly was your role ?

I work in support for the mobile core router side where we use carrier-grade routers but nothing as big as the big Internet core routers.

Hey Maven,

I actually work for a competitor of Cisco but I used to work for Cisco. I guess I'm more of a test engineer than anything else. But I also go to customers and setup/troubleshoot our gear and other vendors. Sometimes I might do a little bug fixing but mostly I'm working with customers trying to get their networks to work.

I'm not comfortable posting my employer here but if you want to continue this conversation go ahead and mail me at smutt AT depht D0T com.
