Batchy NSDI measurements

Please install Batchy and its dependencies properly. For details, check the main README. Start BESS before running measurements.

It is advised to run the measurements on bare-metal. Virtual CPUs tend to cause significant performance fluctuation that leads to distorted results.

To prepare a PCAP file for the l2l3pcap scenario, generate the next hop statistics file first:

python3 ../create_pcap_stats.py PCAP_FILE

We used the 2019 CAIDA trace equinix-nyc.dirA.20190117-130600.UTC.anon for our measurements. To get access to that trace, contact CAIDA here.

Edit the configuration file settings.sh to set BESS install directory, PCAP source file and output directory.

A shell script covers a scenario. The script will fire up Batchy and run measurements. As an example, to run L2L3 measurements: bash l2l3.sh

BESS daemon tends to silently stop processing packets. In that case you will see 0-s after a given control period in Batchy results.
