How to use OML4R to write your OML application

1. Setup your Application

1.1 Download the tar file of your application

sudo su
wget http://www.gpolab.bbn.com/experiment-support/gec17/pingPlus/pingPlus_v3.tar.gz
tar xvzf pingPlus_v3.tar.gz
cd pingPlus_v3
make

1.2 Test connectivity

On the receiver

chmod +x pingPlusListener
ping -c 5 10.10.10.1
ifconfig eth1 0.0.0.0
ping -c 5 10.10.10.1
# ./pingPlusListener 10002


On the sender

ping -c 5 10.10.10.2
ifconfig eth1 0.0.0.0
ping -c 5 10.10.10.2
chmod +x pingPlus
 ./pingPlus 02:26:ae:0e:9b:3e eth1 10002

1. Observe your Output

root@sender:/users/dbhat/pingPlus_v3# ./pingPlus 02:26:ae:0e:9b:3e eth1 10002 5
RQ:'9641+4173' to 2:26:ae:e:9b:3e.

RTT = 0.920166
RQ:'2271+7533' to 2:26:ae:e:9b:3e.

RL:8858+353=9211 from 2:26:ae:e:9b:3e.
RTT = 0.489014
RQ:'447+5696' to 2:26:ae:e:9b:3e.
RL:447+5696=6143 from 2:26:ae:e:9b:3e.
RTT = 0.290039
RQ:'7238+5082' to 2:26:ae:e:9b:3e.
RL:7238+5082=12320 from 2:26:ae:e:9b:3e.
RTT = 0.252930

2. Write your Parser

3. Instrument your Application using LabWiki
