3 Network Coding and Reliable Communications Group Measurement Tools RAW IP Traffic Generator – https://github.com/Wisdom/ipgen https://github.com/Wisdom/ipgen UDP Traffic Generator – https://github.com/Wisdom/udpgen https://github.com/Wisdom/udpgen Evaluate % of successful packets compared to transmitted packets Thanks to: Harry Mussman, Ivan Seskar and Abhimanyu Gosain and others. 3

4 Network Coding and Reliable Communications Group RAW IP Traffic Generator – https://github.com/Wisdom/ipgen https://github.com/Wisdom/ipgen Description: A simple RAW IP TRAFFIC GENERATOR (require sudo) Evaluate % of successful packets compared to transmitted packets Compilation: gcc ipgen.c -o ipgen -O3 There are two types of unsuccessful packages 1. Loss or drop by lower layers. 2. Fail the checksum. This program counts both losses. Usage:./ipgen [-v] -[s|c] [-n NUM_PACKET] [-l PACKET_LENGTH_IN_BYTES] [-b BANDWIDTH_IN_BYTES_PER_SEC] IPADDRESS PORT -v means verbose -s means server -c means client e.g../ipgen -vcl 1000 -b 10000 127.0.0.1 5556./ipgen -vsl 1000 127.0.0.1 5556 4
