Basically, difference means to provide different QOSfor 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. Differentiated Services #@~lo Driver of QoS Technology Hello B A Internet QoS Service Drive Operation Drive • VoIP • IPTV/VoD • Triple-Play • …… • Multi-Service in one netwok • CapEX • OpEX • …… Precise operation mode Extensive operation mode characteristic services Bandwidth QoS Technology Differentiated service Bandwidth Basic service Bandwidth Capability bearing network Capability of service

Security problems we faced today Crimes on IP network: Personal behavior ->organization activities Non-profits -> Profits They may take anything away!!! Security Laws: ISO17799, SOX, … Laws demand: Any information transmitted is traceable!!!
