Tools for working with GENI to do measurements and create overlay topologies

The basic tools allow generating a configuration file with pairwise latencies between each pair of nodes in a GENI manifest. For example, you can run

python parse_geni_manifest.py -f manifest.xml > geni_nodes.txt

This will parse the GENI manifest file to generate a list of nodes with their login info. Then, you can use that list of nodes as input to the ping_all.sh script. The ping_all.sh script will ssh into each GENI node and run a ping test to each other node, and report the results.

./ping_all.sh -f geni_nodes.txt

The output from the ping_all.sh script can then be processed using format_pingout.py. This program will parse the ping results and generate an output file listing the minimum observed pairwise latency for each pair of nodes. The example below assumes the output from ping_all.sh was saved in a file pingoutput.txt.

python format_pingout.py -f pingoutput.txt
