Networking has become just too darn cool. A couple of years ago, decisions were tough enough, what with migration issues, bandwidth concerns and trying to dope out which vendors were going to be around for the long haul.

That's where our second annual Buzz issue comes in. Whether it's policy management, Java in the enterprise, Layer 3 switching or voice over IP, we've peeled back the onion to find out exactly where these trends are coming from - and what they really mean to the enterprise.

Plus, we've set up an online forum: What are the most overhyped technologies you've seen - and what are your strategies for getting to the heart of things?
