“The Constrained Application Protocol (CoAP) is a specialized web transfer protocol for use with constrained nodes and constrained networks in the Internet of Things. The protocol is designed for machine-to-machine (M2M) applications such as smart energy and building automation.”
COAP可以是一个简化版的HTTP,除此之外还支持客户端observe一个资源的变化,从而实现服务器到客户端的推送。
