Label Switch Router (LSR) for NetFPGA

Developed by Algo-Logic Systems for Google Copyright 2011, all rights reserved http://Algo-Logic.com Code distributed through Apache 2.0 software license Last Update: June 15, 2011

To use the LSR NetFPGA Switch,

(1) Starting at the top-level of a NetFPGA base distribution (typically: /home/user/netfpga), extract tarball file to populate lib and project/mpls-switch sub-directories. eg: cd ~/netfpga tar xvf lsr-netFPGA.tar

(2) Download the LSR bitfile to the netfpga nf_download ./bitfiles/mpls_switch.bit

(3) Compile the mpls control and configuration software cd ./projects/mpls_switch/sw ./make

(4) Run the command-line program to initialize LSR switch ./lsr lsr_init Will initialize tables with default values.

(5) For testing,

• connect eth1 (NIC) to nf2c0 (Port 0 of NetFPGA) with short cat5e cable,
• connect eth2 (NIC) to nf2c1 (Port 1 of NetFPGA) with short cat5e cable,
• run wireshark on eth2 to monitor output packets
• and run command like: cd /../pcap_files tcpreplay intf1=eth1 preswap.cap to verify operation of lsr switch with sample packets

(6) To add entries to SRAM to perform specfic swap, pop, push, swap+push, and pop+swap operations, use the command syntax documented by running ./lsr
