Presentation Transcript

  1. IPv4 Internet Router Line-rate OpenFlow Switch GE SRAM FPGA GE Full-rate Traffic Generator DRAM GE GE PCI Host Quad-port Gigabit/second NIC Precision Time Protocol (PTP)

  2. Traffic Generator • Blasts data at full Gigabit Ethernet • Reads data from standard PCAP file • Also Captures and stores incoming data http://netfpga.org/netfpgawiki/index.php/Projects:Packet_generator

  3. IPv4 Reference Router • Four ports of Gigabit Ethernet • Wire-speed Packet Forwarding in Hardware • Discovers Neighbors with Lightweight OSPF http://netfpga.org/netfpgawiki/index.php/Guide#Reference_Router_Walkthrough

  4. OpenFlow Router • Four ports of Gigabit Ethernet • Wire-speed Packet Forwarding in Hardware • Supports OpenFlow Switch Function 0.85 http://openflowswitch.org/netfpga

  5. Quad-Port Gigabit NIC • Provides Four ports of Gigabit Ethernet • Standard PCI Interface • Programmable Hardware • Standard Linux Device Driver GE SRAM FPGA GE DRAM GE GE PCI Host http://netfpga.org/netfpgawiki/index.php/Guide#Reference_NIC_Walkthrough

  6. Precision Time Protocol • Synchronizes time across a network • Accurate to 10 uSeconds • Based on IEEE 1588 http://netfpga.org/netfpgawiki/index.php/Contributed#PTP:_Precision_Time_Protocol

  7. Buffer Monitor System • Provides Four ports of Gigabit Ethernet • Standard PCI Interface • Programmable Hardware • Standard Linux Device Driver GE SRAM FPGA GE DRAM GE GE PCI Host http://netfpga.org/netfpgawiki/index.php/Guide#Reference_NIC_Walkthrough
