We are in the process of delving into the world of enterprise QoS. Our current WAN connections are currently untrusted and they handle the QoS for us with a basic bronze/silver/gold system. We're moving some services to a centralized/virtualized environment and would like to have some control over the QoS on the LAN and across the WAN for critical services (Oracle, SQL, etc.).
So, I've been tasked with learning QoS. Thusfar my experience with it is utilizing the auto-qos features on our switches for our voice traffic.
For now I think we will just be starting out with a 4-class model with the potential to migrate to something a bit more complex once I get my head around it.
So a few questions:
Is there a more up-to-date document than the Enterprise QoS SRND version 3.3?
Also, any reference documents or configuration examples for a QoS beginner would be wonderful if you have any to share. Books, websites, etc. are also welcome.
Thanks in advance,
4.0 has some slight updates
As for books, I recommend this one:
