I agree, that Cisco book is pretty good. But it doesn't really offer an
enterprise-wide solution. My advise is to first verify that you need
QOS in your networks. Once you've established that occasionally (or
more) you're maxing out capacity in certain portions of the network, you
need to first baseline and identify the traffic that's using that
bandwidth. IP accounting, netflow, and NBAR protocol discovery are
great for this. Once you've got data, you want to approach your
management and verify that the traffic you think is most important is
what they think is most important. Then you can apply the multitude of
Cisco techniques to totally block what's not needed, limit or police
what's not real important, prioritize what's time critical and/or
business critical, and best-effort forward what's left. That a real
brief overview, but it's a start.

Hey Joe,
I think that by far that best source for QoS knowledge and understanding
is the Cisco Press book, DQoS. I read it and other books on the topic
and in my opinion, this book has the clearest, most logical explanations
and comprehensive coverage of the topic available today. Off-hand, I
don't have the ISBN or author, but just go to the Cisco Press site and
you can find it there.
