Time-Triggered Ethernet (TTE) sends communication tasks at regular time triggered by a reasonable scheduling timetable to ensure the real-time and safety-critical performance.This paper proposes a scheduling algorithm of TTE based on time-slot partition.The algorithm obtains information of the switches in the network topology, and partitions the scheduling timetable of each end system.According to the routing information of TT traffic, the sending time is configured in the corresponding partition, so as to ensure the conflict-free transmission of TT traffic in the physical link.At the same time, the scattered free time-slots are combined to reduce the delay of RC traffic and to avoid the waste of network resources.Experimental results show that the proposed algorithm has advantages in network resource integration and computing speed while ensuring the schedulability of TT traffic.
