  1. NetFPGA Greg Watson Prof. Nick McKeown, Martin Casado High Performance Networking Group Stanford and many Stanford students… WARFP 2006

  2. NetFPGA • Board • Software • Vendor Tools • Class material Teach Network System design at under-graduate and graduate level classes WARFP 2006

  3. Overview • Motivation • Version 1 • CS344 – Build an IP Router • Version 2 • Research • Where now? WARFP 2006

  4. Motivation • Provide practical experience in designing computer network systems (routers, switches, etc.) WARFP 2006

  5. Version 1 • Custom board • 3 FPGAs • SRAM, 8 10Mb/s Ethernets • Racked – remote development and debugging! WARFP 2006

  6. CS344 – Build an IP Router • 10 week class. Masters/PhD level. • Build a router with: • Hardware path for valid IP. • Software path for ARP, OSPF, invalid. • Provide CLI to manage the router. WARFP 2006

  7. 171.64.5.26 Web Server Web Browser 171.64.5.3 VNS Router software CS344 setup NetFPGA Campus Internet WARFP 2006

  8. Version 2 • Issues with Version 1 • Custom Rack (expensive, complicated) • Slow (10Mb/s) • Software/hardware interface not ideal • Old technology WARFP 2006

  9. Version 2 • PCI, Four 1Gbps interfaces. WARFP 2006

  10. Version 2 512Kx36 SRAM 512Kx36 SRAM RocketIO on SATA Quad Eth PHY 4 x 1G V2P30 RocketIO on SATA Spartan FLASH PCI 32@33MHz WARFP 2006

  11. Typical Student design Eth MAC Student Verilog (e.g. router) To SRAM Eth MAC To SRAM Eth MAC Eth MAC registers DMA Virtex2Pro30 PCI 32@33MHz WARFP 2006

  12. Research • Why? • “Fast and easy to use” • “Enough gates, RAM, and bandwidth to do real network systems” • RCP @ Stanford (congestion protocol) • IDS @ ICSI • Can touch every packet WARFP 2006

  13. Where now • Classroom • Cheap, and easy to use • Develop interesting classes • Funding for support, testing, and development • Exploit on-chip CPUs (embedded systems) • Research • EmuLAB/PlanetLab type configurations? • Easy to use WARFP 2006
