异步事件驱动的物联网服务模型

随着物联网应用的迅速发展，网络服务面对高并发请求，物联网服务和拥有大量在线用户的交通管理与信息网络服务器随时面临巨大访问量冲击，对网络服务质量形成威胁。本文提出了一种高性能网络服务模型。该模型基于EPCIS，用“阶段”划分网络服务，对象化的队列为主要构件，底层采用异步I／O技术，组件内部和组件间的通信采用事件驱动模型构建。设计和实现了一个基于事件驱动模型的异步Socket通信适配子层，用以屏蔽底层0S异步I／O细节。实验证明该模型对高并发请求服务具有较好的可伸缩性，对网络服务的业务流程变化具有较好的的敏捷性和适应性。

Network service model of asynchronous event driven for the internet of things

With the rapid development of the application of Interact of things, the network service in high con- current requests, service for the Internet of things and a lot of online user traffic management and information net- work server facing huge amount of requests impact, pose a threat to the quality of service of the network. A high performance network service model was presented in this paper. The model was based on EPCIS, using the ＂stage＂ division of network service, the object queue as main component, the asynchronous I/O communication technique and component and inter component with event driven model. The design and implementation of a driven model of asynchronous Socket communication based on event adaptation sublayer was used to shield the OS asynchronous I/O details. The results show that the model has good scalability on high concurrent requests services, and business process change on the network service has good agility and adaptability.
