Abstract

With the increasing popularity of time-sensitive network applications and the gradual integration of the Tactile Internet into people’s lives, how to ensure ultra-low latency has become a demand and challenge for network performance. Therefore, it is extremely important to analyze the performance of the Tactile Internet. In this paper, we propose an analytical model based on deterministic network calculus (DNC) to quantitatively derive the end-to-end performance bounds of the Tactile Internet, develop a tandem model describing the communication of the Tactile Internet network, and analyze delay-related traffic parameters, such as arrival rate and burst size. We investigate the variation of the accuracy of the DNC analytical model and the measurement model under different parameters, and verify the accuracy of the proposed DNC analytical model by theoretical derivation and analysis and comparison with the measurement model under the NS3 platform. We discuss the impact of relevant parameters on the delay boundaries to determine which network configuration enables the end-to-end delay to meet the established requirements. This will provide valuable guidance for the design of Tactile Internet architectures.
