摘要
分析了AS6802标准中支持的多种业务消息的传输特性,设计了一种时间触发以太网多种业务消息发送的混合业务调度器。采用发送计划表和允许发送帧长控制,实现了时间触发数据的按时发送。基于允许发送帧长控制和非抢占优先级调度的非时间触发业务发送,保证了带宽利用率,实现了PCF业务的事件触发特性、RC业务的速率限制特性和BE业务的尽力而为特性。混合业务调度器满足了时间触发以太网多业务传输要求。
Analyzes the transmission characteristics of multi-service messages supported by AS6802 standard, and designs a hybrid service scheduler for multi-service message transmission in Time-Triggered Ethernetnetwork. The transmission schedule and frame length control are used to realize the timely transmission of time-triggered data. Based on the frame length controlmechinism and non-preemptive priority scheduling, the bandwidth utilization is guaranteed, and the event triggered characteristics of PCF service, the rate constraint characteristics of RC service and the best-effort characteristics of BE service are realized. The hybrid service scheduler meets the requirement of time-triggered Ethernet multi-service transmission.
