Summary n There are many perspectives on QoS: adjectives provide more precision. n For User-User QoS, customer expectation and application design play a role. n Network QoS Objectives are in terms of packet transfer performance parameters, and are divided into a small number of Classes n E2E QoS Signaling Requirements Development under way in SG 11 and IETF NSIS n Several pieces needed: Subscription, Authorization, Accounting, Priorities
