Research Progress of Traffic Scheduling in Time-triggered Ethernet
Time-triggered Ethernet(TTE)combines time triggered technology with the flexibility,high bandwidth and other characteristics of traditional Ethernet,and solves the problems of high real-time and high reliability that traditional Ethernet cannot meet.Traffic scheduling is one of the key technologies in the TTE standard,which can effectively ensure reliable real-time communication in the TTE network.Firstly,the basic time synchronization mechanism of traffic scheduling is introduced,and the TTE traffic scheduling problem is mathematically described,including the topology of the TTE network,traffic model,and constraint conditions.Then,the research status of TTE traffic scheduling is emphasized,and the advantages and disadvantages of different scheduling algorithms and different application scenarios are analyzed and compared.The types of scheduling traffic,scheduling objectives,and scheduling properties of various scheduling schemes are summarized.Finally,the development direction and trend of TTE traffic scheduling are discussed.
