由于航电系统通信需求的日趋复杂化,对基于FC-AE-1553组网的通信系统需要采用多网络控制器(NC)构建分布式网络环境,如何实施多个控制器之间的控制权分配,并解决跨域业务冲突的问题是其中的关键。为实现多NC协同调度,提出了一种主从NC协作的多NC动态带宽调度机制,采用并发通信方式提高网络带宽利用率,同时提升各类业务的传输保障能力。对于周期性业务采用固定时隙进行传输,对于强时效性突发业务采用抢占式带宽分配,对于一般突发业务按照“先跨域后域内”分别进行带宽分配。通过OMNeT++搭建FC-AE-1553网络仿真平台,结果表明:该调度机制可以满足多NC条件下不同类型通信业务的协同带宽分配和调度,对于周期性业务和强时效性突发业务,可以保障其实时性通信要求;对于一般突发业务,在网络负载不超过57%时也能为其提供合适的带宽进行传输。与单NC集中式相比,当网络负载大于0.5或跨域/域内业务比值大于0.8时,多NC控制具有较明显的时延优势。
