HOL4P4, BMv2 Setup

Follow the regular installation instructions.

DPDK Setup

Clone the kth-step fork of Pktgen-DPDK, check out the for_hol4p4 branch and follow the regular installation instructions.

Setup hugepages on every startup:

sudo python3 dpdk-hugepages.py -p 1G --setup 2G

Then run e.g.

sudo ./test_hol4p4.sh

while ensuring the configuration parameters of the script is what you want.

petr4 Setup

Clone the regular petr4 repository and check out the mininet-interface branch, first install as usual.

The mininet-interface branch requires also to do

opam install rawlink-lwt cohttp-lwt-unix hex

on top of regular installation instructions, as well as changing rawlink.lwt to rawlink-lwt in the bin/dune file.

After make, the a symlink will be located at ./_build/install/default/bin/petr4. It doesn't seem to replace the existing one, that requires make install.

Run the switch by running something like

sudo petr4 switch -i 0@s1-eth1 -i 1@s1-eth2 -I p4include conditional.p4

Note, this needs the virtual network to be set up (s1-eth1, s1-eth2).
