6. Overview of Nile Project Example of Nile Applications: Traffic Monitoring

7. Integrated QoS Management Initial approach: tight coupling System level inter-dependence Control level inter-dependence * Focus: optimal control New approach: loose coupling System level design: orthogonality Legacy compatibility Integrated control * Focus: deployability & robustness

8. Q-Bahn Where the QoS rubber meets the road –Features: Deployability & Scalability * legacy apps running over legacy OS –Primary target: Intra-domain * enterprise, government, educational –Eventual extension: Inter-domain * inter-AS policy barriers System Architecture –Single QoS control currency –Orthogonality –Business model * warranty model Networking client client client server tv card OpenMCU monitor snmp netflow cisco 7206 Hardware Software: legacy app & OS

9. Q-Bahn Testbed –9-node IP-over-SONET backbone –Abilene/Internet2 topology –Cisco 7206 VXR, custom IOS Brings together –Noncooperative game theory –Aggregate-flow scheduling –Traffic theory –Integrated wireline/wireless network Networking scalability, deployability, business model purdue-ios: scalable QoS switching Intel IXP1200 Network Processor DB & Sec Sec
