Google Summer of Code’ 17 with phpMyAdmin – Summary

This post summarizes the work done and tasks accomplished during the last twelve weeks. It was carried out as a part of Google Summer of Code 2017 with phpMyAdmin.

The project involved two separate sub-lists of tasks, one related to phpMyAdmin’s Error Reporting Server and the other related to phpMyAdmin’s selenium test-suite.

Tasks related to Error Reporting Server:

pcap_to_ditg Python library released

Yesterday, I packaged and released my first python library pcap_to_ditg‘s version 0.1.1.

The library can be used to convert the Packet capture files generated from Wireshark, TCPDump etc. into DITG script files. This would make it possible to read a trace file generated from any port of any topology and replay the traffic exactly onto your custom topology. I hope this would go on and help the network researchers while testing their prototypes in real traffic scenarios.

Since last semester, I had been working with Dr. K. Haribabu, who is an Assistant professor at BITS Pilani currently working on the research areas like Software Defined Networking (SDN), Hybrid and cost-effective SDN deployment, P2P networks etc. I co-authored a paper with him which was presented in July, 2016 at the International Network Conference 2016, Frankfurt, Germany. For the performance evaluation, we were in need of replicating real Network traffic and check how our prototype delivers and scales.

I researched and tried out various traffic generators mentioned in this list, but no one was fulfilling our requirements exactly. Moreover, even after one gets the real network traces (for ex, we used one here), since there is no prior knowledge of the topology of the network of the trace, it’s not very simple to replicate it as it is. So, I manually mapped the hosts and IPs in the traces to the hosts in our test topology and we decided that we would use the DITG script files to replay the traffic. Once the mapping is complete, the library would generate the script files for all our hosts, which can then be run as it is.

The library installation and usage details are available in README on Package Index page or on my Github (where mostly its future development should go on).

Share it with your friends if you know someone who might need to use it. Contributions in Pull Requests, Feature Requests, Bug reports etc. are always welcome (through Github tracker).
