Differentiated Services Basically, difference means to provide different QOS for different customers and different services User QoS Highly perceptional, hard to quantify. Application QoS Applications change so do requirements. Network QoS Easy to quantify, well defined. All other QoS can be expressed in these terms. Metrics well defined. Availability Delay Delay Variation Throughput (Bandwidth) Packet Loss Rate.
