摘要：

为提高网络化嵌入式系统的安全性与可靠性,提出一种基于Actor模型的软总线设计方法,以解决分布式全数字仿真测试中系统及组件间的通信问题。采用以Actor模型为中心的发布/订阅机制，实现分布式节点之间的同步、异步通信。在此基础上，提出一种基于线程池技术的任务调度方法，实现Actor模型的协同工作，并通过规则链表进行Actor消息的处理及转发。实验结果表明,与HLA、OpenDDS总线相比,在大数据量并发处理的情况下,该软总线程序执行效率提升30%以上,能够满足网络化嵌入式系统测试对实时性与并发性的需求。

Abstract:

In order to improve the security and reliability of networked embedded systems,a soft bus design method based on Actor model is proposed to solve the communication problem between systems and components in distributed full digital simulation testing.Actor-based publish/subscribe mechanism is adopted to realize synchronous and asynchronous communication among distributed nodes.On this basis,a task scheduling method based on thread pool technology is proposed to realize the collaborative work of the Actor model,and the processing and forwarding of the proposed Actor message through the rule list.Experimental results show that compared with HLA and OpenDDS buses,the execution efficiency of the proposed soft bus program is improved by more than 30% in the case of massive data concurrent processing,which can meet the real-time and concurrent requirements of networked embedded systems testing.

Key words: networked embedded systems, Actor model, distributed full digital simulation, strong real-time, concurrency
