Upper Bound Analysis of TSN End-to-End Delay Based on Network Calculus

Abstract

To analyze the upper bound of end-to-end delay in time-sensitive networks, an improved calculation model of end-to-end transmission delay based on network calculus is derived according to the relevant knowledge of deterministic network calculus. The effects of GCL gate opening time, scheduling period, the overlap of transmission Windows, and different priorities of traffic on the delay index were analyzed experimentally, and the end-to-end worst-case transmission delay of time triggered (TT) traffic in the whole process of traffic transmission was calculated. Finally, through comprehensive analysis of GCL and reasonable configuration of parameters, good transmission capacity of the communication network is ensured, which provides a theoretical basis for efficient deployment of the communication network and optimal allocation of network resources.
