how to run EuhatOfp

by

create three vmware guest machines for example,
ip of no.1 guest machine is 192.168.204.33
ip of no.2 guest machine is 192.168.204.34
ip of no.3 guest machine is 192.168.204.35

setup dpdk in every machine, all script and binary are in the setup directory, refer to <5. setup dpdk> in

compile ofp over dpdk in vmware

modify test/servers.cfg

192.168.204.33:8061
192.168.204.34:8062
192.168.204.35:8063

for every guest machine modify self ip setting in test/ofp_netwrap.cli

in no.1 guest machine

cd test
./release/test 0

in no.2 guest machine

cd test
./release/test 1

in no.3 guest machine

cd test
./release/test 2

then you can check the log files in test/log directory.

how to build EuhatOfp

by

EuhatOfp is a library for peer to peers communication framework through user space tcp stack, now implemented in OFP over DPDK.

1. build ofp over dpdk

compile ofp over dpdk in vmware

2. build EuhatOfp

1

git clone https://github.com/euhat/EuhatOfp.git

modify the paths of dpdk, odp-dpdk and ofp in test/Makefile.

modprobe uio
insmod igb_uio.ko
ifconfig ens33 down

run dpdk-19.11/usertools/dpdk-setup.sh
>>> select and run "Setup hugepage mappings for non-NUMA systems", enter 128
>>> select and run "Bind Ethernet/Baseband/Crypto device to IGB UIO module", will display like

>>>>>> enter 02:01.0
>>> Exit Script

6. test

let the vmware guest machine use NAT.

use ipconfig check ip settings in host machine. for example, my ip for "VMware Network Adapter VMnet8" is 192.168.204.1.
