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. Acknowledgement

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

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

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

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

8. Service Composition Access Provider A Provider B Trust C Metro Technology G Provider F Control E Regional Admin L Trust T Security S Long Haul latency P Bandwidth Q Resiliency R Client Server 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. 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. IP Packet 1. Check IP Dest. Addr2. Routing Table Lookup3. Select Forwarding Path 4. Send packet to output Q

10. Router Programmability?

11. CE FE Programmability: Possible Control Functions Control Intensive computation (2) (3) (1) 1)Control functions that reside wholly in the control plane 2)Control functions that insert software in the critical data path 3)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 CE: Control Element FE: Forwarding Element

12. Programmability: Active Flow Manipulation Forwarding Processor Forwarding Processor Packet PolicyFilters AFM Packet Filte r Packet Action 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
