一种基于TTE调度表的资源分配算法
|
摘要
时间触发以太网(TTE)通过精确的全局时间同步,使时间触发(TT)消息具有严格的时间确定性。TTE交换机在接收不同的TTE端系统传来的TT消息时,TT消息可能会发生冲突从而使数据包丢失。主要提出一种交换机接收端调度表资源分配算法,在保证整个网络时钟精确同步的前提下,通过预先设计好的任务调度表,使交换机在接收各个端系统发送的TT流量过程中避免了消息的冲突,减少了数据的丢失。
Time-triggered Ethernet(TTE)with precise global time synchronization,time-triggered(TT) messages are subject to strict time certainty. When a TTE switch receives TT messages from different TTE end systems,TT messages may collide and data packets may be lost. This paper proposes a resource allocation algorithm for the receiver scheduling table, which ensures the accurate synchronization of the entire network clock. By pre-designed task scheduling table,the switch avoids the TT traffic sent by each end system Message conflict,reducing the loss of data.
