1. NetFPGA - an open network development platform Presented by: Andrew W. Moore (University of Cambridge) andrew.moore@cl.cam.ac.uk MSN2008 http://NetFPGA.org (some slides courtesy John W. Lockwood)

2. What is the NetFPGA? PC with NetFPGA 1GE FPGA 1GE 1GE Memory 1GE NetFPGA Board NetworkingSoftware running on a standard PC CPU Memory PCI A hardware accelerator built with Field Programmable Gate Arraydriving Gigabit network links

3. Introduction Don’t think of this as an FPGA thing, just as programmable hardware. Who uses the NetFPGA Educators Students Researchers How they use the NetFPGA To run the Router Kit To build modular reference designs IPv4 router 4-port NIC Ethernet switch, … To create new networking systems

4. How is the NetFPGA Used?User-space development, 4x1GE line-rate forwarding OSPF BGP My Protocol user kernel Routing Table “Mirror” 1GE FPGA Fwding Table Packet Buffer 1GE 1GE 1GE 1GE IPv4 Router 1GE Memory 1GE 1GE Usage #1 CPU Memory PCI

5. How to use a NetFPGA in a Network? Internet Gateway Network Servers running email andweb services Network of NetFPGA Routers Gigabit Ethernet Links Clusters of PCs and Workstations accessing serversand running Peer-to-Peer applications
