Toward PrimoGENI Constellation for Distributed At-Scale Hybrid Network Test

PrimoGENI provides a GENI aggregate interface through which experimenters can launch large-scale network experiments on GENI resources consisting of both simulated network and real instances of network applications directly running on either virtual or physical machines. Real network traffic generated by the network applications can be introduced into the simulated network in real time and be subjected to proper delays and losses according to the simulated network conditions. To leverage the previous PrimoGENI prototype activities, PrimoGENI Constellation is a newly launched project, which will focus specifically on facilitating distributed at-scale hybrid experiments for real-world high-impact applications. In this paper, we provide an overview of the major achievements of PrimoGENI, and more importantly, discuss the ongoing efforts in PrimoGENI Constellation aiming to achieve the full potential of the hybrid network experiment approach. The main thrusts of PrimoGENI Constellation include: 1) supporting at-scale network experiments potentially distributed on different types of GENI resources in accordance with the GENI experiment workflow, 2) focusing on target applications supporting prominent and high-impact future Internet research, and 3) building the user community through extensive education and research training, and online archives of experiment results and user experiences.
