基于微服务架构的物联网中间件设计
|
摘要
以传统SOA架构搭建的物联网系统在扩展能力和异构设备持续集成方面存在不足,且随着物联网生态系统概念的成熟,如今物联网更强调与第三方物联网系统间的互操作支持能力。为解决上述问题,提出了基于微服务架构的物联网中间件,阐述了其内部组成和功能目标,详细研究了其中异构设备的服务抽象过程以及多用户环境下的冲突解决机制。通过微服务架构的灵活性和服务间的松耦合特点,提出的物联网中间件除了能保证异构设备的动态集成和统一的服务化抽象外,还能有效支持第三方物联网系统的接入。最后通过实例验证了该中间件设计的可行性。
IoT(Internet of Things) systems based on traditional SOA(Service-Oriented Architecture) are poor in sca-lability and are hard to support heterogeneous devices with continuous integration.Moreover,IoT platforms' interope-rability with third-party becomes crucial as the IoT ecosystem enhances.Thus this paper proposed a general IoT middleware based on microservices architecture to solve the problems mentioned above,throughoutly researched the internal components and their effects,especially studied the service abstraction process of heterogeneous devices and the conflict resolution mechanism in multi-user enviroment in detail.Through the flexibility of the microservice architecture and the loose coupling between services,not only heterogeneous devices but also third-party IoT systems can be integrated at runtime as services.In the last place,actual devices are used to verify the applicability of this middleware.
