Performance Evaluation of QUIC Vs. TCP for Cloud Control Systems

QUIC is a UDP-based transport layer protocol developed by Google that is designed to deliver lower latency performance than TCP. However, its performance has been found to vary across different studies due to discrepancies in targeted applications and experimental configurations. Therefore, the protocol evaluation is heavily dependent on the QoS requirements of the target application. In this paper, we evaluate the performance of QUIC for cloud control systems by comparing it with TCP and TCP-based protocols. We performed the evaluation under two different cloud environments: a private edge cluster and public cloud. Different networks were utilized under multiple scenarios, including 5G, Ethernet LAN and Internet. Our objective is to determine if QUIC can meet the QoS requirements of a cloud control system. By focusing on this specific use case, we aim to provide a more comprehensive understanding of the potential benefits and limitations of QUIC on cloud control systems. The results of our evaluation suggest that the performance of different protocols varies based on the characteristics of different control systems. However, QUIC offers more advantages in deploying and enhancing time-critical systems.
