Network Coding and Reliable Communications Group Replacing WiMAX’s HARQ/ARQ with Network Coding: an Implementation Surat (Au) Teerapittayanon [email protected] Network Coding and Reliable Communications Group Architecture 2 Network Coding and Reliable Communications Group Measurement Tools • RAW IP Traffic Generator – https://github.com/Wisdom/ipgen • UDP Traffic Generator – 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 Network Coding and Reliable Communications Group • RAW IP Traffic Generator – 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 Network Coding and Reliable Communications Group • UDP Traffic Generator – https://github.com/Wisdom/udpgen • • • Description: A simple UDP TRAFFIC GENERATOR Evaluate % of successful packets compared to transmitted packets • • Compilation: gcc udpgen.c -o udpgen -O3 • • • • There are two types of unsuccessful packages 1.
