The availability of correct ground truth information is critical to many experimental scientific activities. In particular, the accuracy in determining the application and protocol behind each flow in an Internet traffic trace is necessary to allow advances in Internet measurement research, such as the study of new traffic classification mechanisms.
gt is a software suite for associating accurate ground truth information
with Internet traffic traces. By probing the monitored host's kernel to obtain
information on open Internet sessions, gt gathers guaranteed truth at the
application level.
gt has been designed and developed by the
NTW team
in cooperation with Politecnico di Torino, with
further contributions from CAIDA.
