  1. NICTA-SEACS Seminar D. B. Hoang Advanced Research in Networking IICT – Faculty of IT University of Technology, Sydney A Programmable Platform for Internet Service Architecture

  2. Acknowledgement Reference Paper:T. Lavian, D. B. Hoang, F. Travostino, P. Wang, S. Subramanian, and I. Monga, “An Extensible, Programmable, Commercial-grade Platform for Internet Service Architecture,” to appear in IEEE Transactions on Systems, Man, and Cybernetics, Autumn 2003. • This is a joint work between D.B. Hoang and other researchers at Nortel Network as listed in the paper below.

  3. Outline of the talk • The current Internet? • Next Step? Service Architecture • Router programmability • Programmable edge device as a service platform – its architecture • Some applications • About ARN

  4. Convergent IP (Connectivity) Wireless Internet (Mobility, Location) Optical (Scalable bandwidth) Current Internet Serves well as a connectivity infrastructure Does not handle mobility well Does not possess adequate intelligence to deal with bandwidth

  5. Here Great infrastructure for connectivity Internet – Where do we go from here? Next Generation Networks: Adapt to people, not the other way around! • Mobility • Services • Services on-demand • Resource Sharing What we need is a service architecture

  6. Convergent IP (Connectivity) Optical (Scalable bandwidth) ARN Wireless Internet (Mobility, Location) ARN Positioning ARN : Services and Service Enabling Mechanisms

  7. Programmable Service Platform Domain 1 Domain 3 Domain 2 • Can introduce services on-demand • Can compose/negotiate end-to-end services • Can allocate resources (computing & storage) • Provide strong security • Can address mismatches Internet Service Architecture – Programmable Service Platform Programmable Service Platform

  8. Trust C Resiliency R Security S Control E Provider B Server Bandwidth Q Trust T Provider F Provider A latency P Admin L Technology G Access Long Haul Client Regional Metro Service Composition • How are we composing the next generation Internet? • Service Architecture instead of Connectivity Architecture • Composing end-to-end services by negotiation • Deploying Optical Agility with Programmability and Scalability properties

  9. IP Packet 1. Check IP Dest. Addr 2. Routing Table Lookup 3. Select Forwarding Path Packet Processing in a traditional IP Router • Look at the destination address • Identify routing-table entries for a forwarding path • Select the best match using longest prefix matching for the IP address • Send the packet out to the output queue for the correct outgoing interface. 4. Send packet to output Q

  10. Router Programmability?

  11. (1) Control Intensive computation CE (2) (3) FE Programmability: Possible Control Functions CE: Control Element FE: Forwarding Element • Control functions that reside wholly in the control plane • Control functions that insert software in the critical data path • Control functions that allow control entities to act both in the • control plane and in the data forwarding plane without adding • software in the data path

  12. Policy Filters Programmability: Active Flow Manipulation • A key enabling technology of Openet • Two abstractions • Primitive flows • Primitive actions • Customer network services exercise active network control • Identifying specific flows • Apply actions to alter network behavior in real-time AFM Action Filter Packet Packet Forwarding Processor Forwarding Processor Packet

  14. Programmable edge device as a service platform

  15. Openet/Alteon Apps Apps Unified Service Interfaces iSD JDiffServ JFWD JSNMP UNI NASA UNI Internet Optical Networks or Wireless Networks or Converged IP Networks iSD Programmable Service Platform • The programmable service platform is positioned at the edge network. • Accommodating services and intelligent agents for policy negotiation, addressing mismatches, etc.

  16. Features of the Platform • Enabling services on-demand • Preserving the hardware data path • Differentiating traffic based on application contents • Accommodating powerful computation components • Accommodating real-time AFM • Extensible resources
