If you understand the title of this post then you have headed down the road to CCNP. I was actually excited to begin ONT until I got into the book. Each book on the CCNP list is written by a different author, meaning some books match one person’s learning style and some match others. The ONT book does not seem to match mine.

The reason I am so interested in QoS right now is because we are having QoS is a big topic with a remote hosted application and we/they (the hosting company) had to implement some QoS for a couple of .pdf printers that were swamping the connection.
