卫星通信基于Pub/Sub软件的应用研究

卫星通信设备软件中,需要与很多的设备和模块进行交互,这些设备和模块不断产生和消费数据,需要一个实时、高效、可靠、独立性强的通信模型来构建软件架构。而基于Pub/Sub模式的通信模型是一个非常适用于规模化、松耦合的分布式系统中,因此将两者结合是一个非常好的尝试。文中对Pub/Sub模式的通信模型进行了详细介绍,对其3种实现方式进行了优缺点分析,并基于卫星通信应用提出了改进意见。

In the software of satellite communication equipment, many devices and modules need to interact. These devices and modules constantly produce and consume data. A real-time, efficient, reliable and independent communication model is needed to build the software architecture. The communication model based on Pub/Sub mode is very suitable for large-scale and loosely coupled distributed systems, so it is a very good attempt to combine the two. In this paper, the communication model of Pub/Sub mode is introduced in detail, the advantages and disadvantages of the three implementation modes are analyzed, and the improvement suggestions based on the application of satellite communication are put forward.
