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/
