Real-time Emulation of MASQUE-based QUIC Proxying in LTE Networks using ns-3

Abstract

Tools for real-time emulation of mobile networks are valuable for researchers due to the high amount of time and resources it allows to save compared to carrying out measurements in live networks. In this paper we present the rationale, design and prototype implementation of a novel net device in the ns-3 open source network simulator that allows for end-to-end real-time emulation of LTE networks with real endpoints. We then show the performance evaluation of a QUIC proxy built on MASQUE using our emulated LTE setup. Our results confirm the intended behavior of the implementation, however, we also show the limitations of the real-time capabilities of ns-3.
