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/
