摘　　要：实时交换机可为用户提供微秒级硬实时通信性能,在航空航天领域具有广阔的应用前景。本文提出采用硬件优先级队列来实现FC实时交换机,以支持航电统一网络的硬实时通信。标准的FC协议采用虚电路方式支持实时通信。相对于虚电路方式实现的实时通信,本文设计的FC实时交换机具有实时通信延迟小、系统吞吐量高等优点。Real-time switch can provide user with the function of hard real-time communication in microsecond, and it can be used in the field of aviation and space flight broadly. The paper puts forward a method to realize FC real-time switch based on hardware priority queue. FC standard adopts virtual circuit to realize real-time communication. Comparing to virtual circuit, the method proposed in the paper has less communication delay and higher network throughout.
