3. Overview (1/2) QoS Signaling Protocol AAA infrastructure

4. Overview (2/2) Design Goals: –Diameter interaction independent from a particular QoS signaling protocol –QoS parameter description independent from specific link layer technologies –Ability to deal with different authorization scenarios Review comments captured in issue tracker: http://www.tschofenig.com:8080/diameter-qos/
