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

  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/

  5. Questions?

  6. Comparison:3GPP QoS Architecture and Diameter QoS • 3GPP • Two interfaces for QoS authz. • Builds on top of 3GPP Diameter flavor • SIP and 3GPP QoS description and flow identification • Application layer signaling AF Gq IMS Signaling (SIP) Charging (DCC) PDF Go UE GGSN Data/PDP Context • Diameter QoS • Generic QoS description and Flow identification • Build-in accounting and charging (time-based) • Number of authorization scenarios AF/PDF Application layer signaling (optional) QoS Request QoS requesting Node QoS Node Data
