This repo provides evaluation scripts to test performance of Partov and compare it with performance of Hping3 (a program created specially for sending different kinds of packets; as a base line for comparisons) and with performance of NS-3 (a famous network simulator).
You can run prepare.sh file to download NS-3, PartovNSE, and CF codes and compile/prepare them automatically. The script will warn about possible problems which may need manual intervention. Those cases are listed below:
- NS-3 requires python2 and can not work with python3. If you faced any error during preparing NS-3, make sure that python2 binary exists and works. Then resume the prepare.sh script again,
- When the partovnse.git folder get created, use .sql files in deploy/bin folder to create database and a user for running evaluation scenarios. Either create a user with 'paper' username and '1234' password or edit the credentials of created user in the info.sh file,
- Either libpcap 1.5.1 must be installed or backward compatibility for pre-1.0 libpcap API must be enabled. For enabling backward compatibility see the INSTALL guide in the partovnse.git/ folder.
Following files must be edited manually:
- The ns-allinone-3.19/ns-3.19/src/emu/examples/emu-ping.cc file: There, update 3 items:
- interface name which is currently set to enp2s0,
- default local IP address which is currently set to 192.168.42.101 (select an IP within your local network IP range),
- gateway IP address which is currently set to 192.168.42.1,
- The cf.git/info.sh file: Update user and pass parameters there (to be equal to credentials of user that you have created in the PartovDB database),
- All files starting with config in the partovnse.git/PartovServer/deploy/config/ folder: Update database connection information, interface name, IP address and MAC address of gateway, and IP address of virtual routers installed on those network interfaces,
- All .map files in the partovnse.git/PartovServer/deploy/config/ folder: Update interface name,
- The emulation-ES3.1.map and emulation-ES3.2.map files in partovnse.git/PartovServer/deploy/config/ folder: Update next-hop with IP address of the gateway,
- In a terminal, go to partovnse.git/PartovServer/deploy/bin/ folder and run ./setcapability.sh to give packet injection capability to created Partov binary executable file.
First double check that above tasks are completed correctly. If everything was OK, you must be able to run hping3 to ping some host on the Internet by these commands (as root):
hping3 -c 3 -i 1 -d 1024 -1 126.96.36.199
and also be able to do the same with the NS-3, using following commands (again as root):
cd ns-allinone-3.19/ns-3.19/ ./waf --run src/emu/examples/emu-ping
and do the same using Partov by following commands (as a normal, non-root, user):
cd partovnse.git/PartovServer/deploy/bin/ ln -f ../config/emulation-ES3.1.map ../config/routers.map ln -f ../config/config-emul-with-timeout.ini ../config/config.ini ./partov
and watch sent/received packets using tcpdump program. If you do not see packets as expected, check installation guides and readme files of related part and fix the problem manually before moving forward.
Then, go to scripts folder and run evaluation scripts one by one to obtain experiments results within the outputs folder. Each script will print additional messages about its progress and an estimation about required time to complete that experiment. For a more detailed description about what is being performed in each evaluation scenario, look in the evaluation-guide.md file.
After completion of each evaluation script, you can find a message about created output file(s). Copy them from the outputs folder to the plots folder and run corresponding GnuPlot scripts to generate eps figures from obtained data files. Use epstopdf program to convert eps figures to pdf figures afterwards. Some figures like boxplots which are more complicated can not be rendered correctly in raw eps form and must be converted to pdf to become correctly viewable. You can also use plots/prepare-plots.sh script to generate all plots at once.
