基于工厂方法模式嵌入式通信中间件设备管理框架设计与实现

通信中间件屏蔽了底层网络通信设备,为上层应用程序提供统一消息处理接口,在嵌入式软件中得到了广泛的应用。由于嵌入式软件需求多样、资源受限,通信中间件需要根据项目需求管理特定的网络通信设备。对网络通信设备的管理能力,决定了通信中间件软件的扩展能力和灵活性。基于上述背景,本文基于工厂方法模式设计了嵌入式通信中间件设备管理框架,对具体网络通信设备的管理和使用进行了抽象,实现了通信中间件业务逻辑与具体设备的解耦,提高了嵌入式通信中间件的扩展能力。

Design and implementation of device management framework in embedded Communication Middleware based on The Factory Method Pattern

The communication middleware shields the underlying network devices and provides unified message processing interface for the upper application program,which is widely used in embedded software.Due to the variety of embedded software requirements and limited resources,communication middleware needs to manage specific network devices according to project requirements.The management ability of network equipment determines the expansion ability and flexibility of communication middleware software.Based on the background above,this paper designs a device management framework for the embedded communication middleware based on the factory method pattern.Through the abstracted device factory and communication components,the communication middleware software function is decoupled from the specific devices,thereby improving the expansion ability of the embedded communication middleware.
