Embodiment Construction

[0034] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0035] A kind of RESTful-based ubiquitous network publish / subscribe middleware model of the embodiment of the present invention, this RESTful-based ubiquitous network publish and subscribe middleware is made up of following several parts:

[0036]Publish / subscribe middleware basic model;

[0037] Subscribe to the message format, process and subscription condition filter in the middleware;

[0038] Publish the message format, process and message delivery mechanism between nodes in the middleware;

[0039] Fault tolerance mechanism for handling pub / sub middleware error messages.

[0040] The RESTful-based "publish / subscribe" model can not only provide one-to-many, many-to-one, and many-to-many asynchronous communication modes at the same time, but also remove the time and space constraints of users in the ubiquitous network, that is, loose ...

Abstract

The invention discloses a ubiquitous network publish-subscribe middleware model based on RESTful, and belongs to the technical field of communication. The publish-subscribe middleware model comprises a publish / subscribe middleware base model, a message format, flow and subscribe filter in a subscribe middleware, a message format, flow and node-to-node message delivery mechanism in a publish middleware and a fault-tolerant mechanism for processing publish / subscribe middleware error messages. Compared with the prior art, based on a REST architecture, compared with an SOAP (simple object access protocol) and a WSDL (web services description language), the model has the advantages that bidirectional nodes are used, the number of functional modules is decreased, and a message consumer can timely and reliably obtain published interested messages through the middleware while a many-to-many communication mode in a ubiquitous network is realized by setting the middleware for interaction between a message producer and the message consumer in the ubiquitous network, so that the message producer and a message subscriber are completely decoupled in terms of time and space.

Description

technical field [0001] The invention belongs to the technical field of communication, and relates to a RESTful-based ubiquitous network publish-subscribe middleware model. Background technique [0002] Traditional communication modes (such as client / server, RPC calls, message queues, etc.), send messages and wait for responses, so that there is a tightly coupled relationship between the requester and the sender of the message in time and space. In the face of large-scale The distributed system seems powerless. By using the publish-subscribe middleware model, message producers and subscribers can be completely decoupled in time and space, and a many-to-many communication method can be realized. REST, as a way of designing web services, relies less on proprietary middleware (such as an application server) than SOAP and WSDL-based approaches. Combining this with REST and middleware leads to a better subscribe / publish model. Contents of the invention [0003] In view of thi...
