  1. Service-enabled NetworksFrom The Network to My Network

  2. Four wheels traction CAGR to 2001 Internet Telephony Bring more quality Optical Internet Bring more capacity eBusiness Bring faster cycle times Wireless Internet Extend reach

  3. What’s the scoop—the techies’ view Very high-value traffic coexists with low value, low pay off traffic, all within the same commodity infrastructure TTM and product cycles make software reuse a must—enough stovepipes, layers are back with a vengeance! Increasingly, “impedance mismatches” in the network generate opportunities for intelligent edge adaptation Network wires are now much faster than I/O busses—it’s time to bring the optical revolution into servers/storage Standardization lags behind the mighty innovation curve— the IETF process hardly matches a trillion dollar business

  4. What’s the scoop—the biz view ASPs and eBiz test the market for new services, non stop— many fail, but they’ve thrown a monkey-wrench into the net Hardware innovations are fueling a steep innovation curve— what a great time for disruptive technologies to snowball! Customers demand new soft features in network gear—manufacturers cannot keep up with fast (contrasting) reqs Personalized customer care stipulations are strategic for customer expansion and customer loyalty

  10. Kiss “The Network” Goodbye!!! How about a “white-sheet” network with nodes exposing programmable control to 3rd party code? How about passing on to entrepreneurs and service providers the freedom to formulate the high pay-off services for which they have found a market For this, we will need new levels of abstraction

  11. Much like … Fred Smith invented the FedEx business in 1973, after recognizing the significance of predictable movement of packages. Smith has always used the same roads, airports, cars, and types of planes as the U.S. Postal Service … but he has programmed his own resources to work in a novel way

  12. Analogy terminals in airports, railways, roads fleet, personnel parcels APIs and resources in telephones, routers, switches Ubiquitous, shrink-wrapped software PDUs (meeting the various SLAs)

  13. Service sampler Entrepreneurs will run code inside the network for: • Ad-hoc routing or policy definition for VPNs • New protocol versions or features deployment • Multicast protocols and support tools instantiation • Stateful packet capturing; “intrusion detectors with legs” • Intentional directory services • Content-sensitive load balancing and caching • Diagnostic agents (e.g., for loops, SLAs infringements, etc.) • Customizable IP Accounting (e.g., to support “pay-for-what-u-use”)

  14. 2) ABS detect lockups and will pump brakes 1) Brake! Why inside the network and not e2e? ABS brakes are a Turing machine exploiting locality

  15. Why inside the network and not e2e? (2) • Fan-in/fan-out • Centralization/De-centralization • Visibility • Affinity with data that only lives in the network • Localization

  16. Location, location, location Service-enablement will prove most effective where “impedance mismatches” occur in the network • Wireline vs. wire-less • Secure vs. non-secure • Customer-premises vs. Content-provider-land • SLA (x) vs. SLA (y) • Low TCO vs. High TCO • Resource-constrained vs. unwashed unlimited computing A service-enabled box can wear multiple hats

  23. Top 5 Challenges to Service-enablement What do the APIs look like Scalability Service guarantees Security “I’ve got a hammer and everything looks like a nail”

  24. Who’s looking into this? Programmable Nodes community Active Networks community Akamai-like infrastructures Jain Intel’s Phoenix platform Lucent’s softswitch Nortel’ s openet.lab platform

  25. Programmable Nodes Current Nodes • Vertically integrated • Primitive scripting Programmable Nodes • Manufacturers publish extroverted APIs • I can port code and extend such network nodes • Alternately, I can operate the APIs remotely • APIs’ target audience: Manufacturers, ISPs References • IEEE P1520 • Industry alliances

  26. Active Networks Current Networks • Data in the packet, program in the network nodes • Effective, but inflexible Active Networks • The program travels with the packet, end-to-end • Flexible, but ... how about security, interoperability? • Most ambitious thus far • Target audience: ISPs, end-users References • DARPA Active Networks

  27. Partial overlap Active Networks Programmable Nodes Manufacturers extend routers Users extend routers ISP extend routers

  28. Nortel’s Openet.lab It’s an incubator for service-enabled network nodes and sample services It provides: • JVM-emancipated prototypes of Nortel routers • Java APIs to MIBs • Java APIs to Forwarding Planes, packet capturing • A runtime environment for downloaded code It’s popular among researchers (DARPA, CSIRO, …) Free downloads from http://www.openetlab.com

  32. Fast-paced innovations paint an optimal scenario for service-enablement in the network • Service-enablement is an effective way to overcome network “impedance mismatches” • It brings friend-services and friend-content closer; it pushes foes further away • Kiss The Network good bye. It’s My Network now! Conclusion

  33. Closing remark Back then, thrust wasn’t a problem; control was Likewise, network bandwidth growth is just fine; control does demand our collective efforts
