Overview of Nile Project Example of Nile Applications: Traffic Monitoring
Integrated Qo. S 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
Networking Q-Bahn • Where the Qo. S 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 Qo. S control currency – Orthogonality – Business model * warranty model client Open. MCU tv card server client cisco 7206 monitor cisco 7206 Hardware Software: legacy app & OS snmp netflow
Networking • Q-Bahn Testbed – 9 -node IP-over-SONET backbone – Abilene/Internet 2 topology – Cisco 7206 VXR, custom IOS Network Processor Intel IXP 1200 purdue-ios: scalable Qo. S switching • Brings together – Noncooperative game theory – Aggregate-flow scheduling – Traffic theory DB & Sec – Integrated wireline/wireless network scalability, deployability, business model Sec
