3. Dec. 3-5, 2001 3 DARPA AN PI Meeting Our Mission Developing enabling mechanisms for the AN technology transition and Knowledge transfer Finding good industry relevance research and technologies and incorporating them into future products Deploying commercial high performance network devices to construct a programmable AN platform —Supporting customizable network intelligences —Supporting excellent AN-specific research projects —Addressing AN and optical networking issues

4. Dec. 3-5, 2001 4 DARPA AN PI Meeting 1 st Expl: Collaboration with a Major Carrier A major Carrier is interested in some aspects of the research and technologies incubated by the AN community The main value is to role out new services – and fast Unfortunately - the current market condition slowed down the interest (great direction – but no money now) 

7. Dec. 3-5, 2001 7 DARPA AN PI Meeting Challenge 1: Infinite Bandwidth Challenge 1: Infinite Bandwidth Why this change the playground? 3-4 orders of magnitudes bandwidth growth in many dimensions –Core – Optical bandwidth - (155mbps  1Tbps) –LAN – (10mbps  10Gbps) –Access – Cable, DSL, 3G – (28kbps  10mbps, 1.5mbps, 384kbps) Silicon Wire-speed routing How to benefit from these valuable resources? For example: streaming media on the net? –Peer to Peer – driving bandwidth –Streaming video, multicast, video is coming –Web traffic will be minor (streaming is constant)

8. Dec. 3-5, 2001 8 DARPA AN PI Meeting Challenge 2: Programmable Networking The streaming media demand & the infinite bandwidth drives the need for programmability and dynamic services on the net Need programmability on commercial devices to address this challenge since software based routers cannot address it adequately. However, unlike Linux routers and software based routers, software cannot be added to the data plane —Data plane : Wire speed silicon forwarding, multi Gigabit —Control plane : –Can’t see the data in wire speed. –Can dynamically modify the silicon knobs

9. Dec. 3-5, 2001 9 DARPA AN PI Meeting Our Solution: Programmable Services Service-enablement will prove most effective where “impedance mismatches” occur in the network — Optical vs. Wireline (3-4 oom) — Wireline vs. wire-less (3-4 oom) — Secure vs. non-secure — Customer-premises vs. Content-provider-land (3-4 oom) — SLA (x) vs. SLA (y) — Resource-constrained vs. unwashed unlimited computing A service-enabled box can wear multiple hat oom – Order of Magnitude

10. Dec. 3-5, 2001 10 DARPA AN PI Meeting Our Works We have implemented programmable Gigabit Routing Switch (backplane 256 Gbs) AN in the control plane (slows down in the data plane) Capable of dynamic monitoring and modification of silicon knobs —The granularity is streams and not packets —Short time granularity (part of apps and not human intervention, keyboard, telnet, cli, snmp) Enabling New Types of intelligence on programmable network device to handle Infinite Bandwidth resources, Wire speed routing capability, and nontrivial Streaming media application.
