Well I'm back. Lots of geek stuff and lots of Jack Daniels and Coke.
Biggest takes from the sessions I took:
QoS has really matured - marking at the edge using diffserv has really advanced. The tools availible at the WAN and VPN edge have also advanced to make use truly complete control on what app does what on a slow line (read...everything but a LAN.)
Cat6K is continually adding incredible features at wirespeed
Cisco is pushing voice big time - good or bad? It depends on where you look. I'm still in between.
Wireless is a big push - I still don't like it. I kept hearing "Wireless is a viable and cheaper option than a wired network". I don't buy it. Wireless in my mind (and from experience) is a big steaming slow hunk of crap.
Multicast is coming of age and lots of new features and design guidelines mean all you gurus should brush up on it...a lot has changed in the last 1-2 years.
DVDM and optical are (as predicted) making leaps and bounds squeezing every lambda out of a single fiber with the routing/switch power to boot.
So what happened to optical routing?
