新型FC逻辑架构中ASM通信设计

Design of ASM Communication in New FC Logic Architecture

光纤通道匿名用户消息协议(FC-AE-ASM)在航空电子环境子系统的互联通信方面应用广泛,该协议采用的停止等待协议不仅占用处理器资源,还影响数据发送效率。该研究从FC硬件结构和逻辑架构上进行改进,在ASM通信上进行大队列模式优化管理设计,使同类型消息共享缓冲。方案对比及工程实践结果表明,该设计能够增加支持的消息数量,减少逻辑的资源使用量,同时满足实际使用需求。

Fibre Channel-Avionics Environment-Anonymous Subscriber Messaging(FC-AE-ASM)is widely used in the interconnected communication of avionics environment subsystem.The stop-wait protocol adopted in this protocol not only occupies processor resources,but also affects the efficiency of date transmission.By improving from FC hardware and logic architecture,the large queue mode is designed to optimize the management so that the same type of message can share buffer in ASM communication.The results of the scheme comparison and engineering practice show that the design can increase the number of messages supported and reduce the use of logical resources.It can satisfy actual use needs at the meantime.
