  2. Genesis Team • Andrew T. Campbell (Columbia U) • Michael E. Kounavis (Columbia U) • Hermann de Meer (U of Hamburg, Germany) • Kazuho Miki (Hitachi, Japan) • John Vicente (Intel Corporation, USA)

  3. Observations • OPENSIG andactive networks • Can you characterize programmable networks • Networking technology • Degree of programmability • Programmable communications abstractions • Programming methodology • Architectural domain • Common ground • making networks more programmable • Enabling technology

  4. Architectural Viewpoints communication & computation support Computation model Communication model Application layer Transport layer Network layer Data link layer Management plane Control plane Transport plane

  5. Network programming interfaces Communication Model Programmable Network Architecture Network Programming Environment Computational Model Node Kernel Node Kernel Node interfaces Node HW Node HW Generalized Programmable Framework

  6. Comparison of programmable network projects

  7. Some Thoughts • Open Programmable Interfaces • Virtualization through Abstractions • Virtual Networking

  8. Director’s Meeting Conference Call Simulation Network Field Sales Network President’s Video Address to Sales Team Manufacturing Network Sales & Marketing Network IT Task Force Mgmt Network Company X Physical Network Infrastructure Virtual Networking • Requirements: Group Collaboration • Isolation • Security & privacy • Connectivity - QoS • Challenge: Automation • Deployment • Configuration • Virtualization • Separation • Resource partitioning • Management

  9. Network Objects Topology graph Resource requirements Profiling Refinement Object deployment Monitoring Admission control Management Spawning Visualization Resource partitioning Genesis Life Cycle Process Profiling Virtual Network Life Cycle Management Spawning

  10. Is there a VN Technology Gap? • State-of-the-art • How do I setup a VN in the same time it takes to open a socket/bind or RPC? • What is the middleware glue to do this? • Where are we today in the field? • TEMPEST, NETSCRIPT and X-Bone • Genesis • The middleware: a virtual network operating system? • Profiling, spawning, managing, architecting
