PILOT: A Methodology for Modeling the Performance of Packet Connections

Network Services automation requires predictable Quality of Service (QoS) performance, measured in terms of
throughput, delay and jitter, to allow making proactive decisions. QoS is typically guaranteed by
overprovisioning capacity dedicated to the packet connection, which increases costs for customers and network
operators, especially when the traffic generated by the users and/or the virtual functions highly varies over the
time. This paper presents the PILOT methodology for modeling the performance of packet connections during
commissioning testing in terms of throughput, delay and jitter. PILOT runs in a sandbox domain and constructs
a scenario where an efficient traffic flow simulation environment, based on the CURSA-SQ model, is used to
generate large amounts of data for Machine Learning (ML) model training and validation. The simulation
scenario is tuned using real measurements of the connection obtained from a set of active probes.
