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

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

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

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

6. 6WARFP 2006 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.
