| Summary: | In order to meet the demand for real-time and highly reliable data transmission, the Ethernet standard for terrestrial networks introduces time-sensitive networking (TSN), which effectively reduces delay jitter by the means of traffic shaping and traffic scheduling. However, the deployment of terrestrial networks is limited by environmental factors, and it is difficult to cover remote areas and airborne service objects, which can’t meet the strict requirements for delay jitter. Considering that low-orbit satellite networks have the advantage of wide-area three-dimensional coverage, the applicability assessment of TSN technology in low-orbit satellite networks was carried out. OMNeT++ was used to construct a simulation platform for time-deterministic technology in low-orbit communication networks, and the design principles and workflow of each functional module of the simulation platform were introduced in detail. Meanwhile, the key mechanisms were analyzed in depth. Through simulation evaluation, it verifies the performance advantages of TSN technology in guaranteeing the end-to-end delay, delay jitter, and packet arrival rate of time-sensitive services in low-orbit satellite networks. |
