An application cross-domain access method based on the multi-domain collaborative architecture of the Internet of Things

Abstract

The invention belongs to the field of computer application technology, and discloses an application cross-domain access method based on the multi-domain collaborative architecture of the Internet of Things. A third-party application user sends an access request, and the request is first searched in the data cache module, and there is no mapping relationship or the authorization time expires. Then initiate a request to the central domain, and the central domain extracts key data through parsing and processing; if there is a mapping relationship, it directly accesses the corresponding data domain for access control; the central domain forwards it to the identification management center for identification, and the identification management center returns the identification result to Central domain; the central domain forwards to the account verification and binding module, and the account verification and binding module returns the result data to the central domain; the central domain maps the result data back to the third-party application, and caches it in the data cache module; the third-party application Users send data access requests to each data domain through IP addresses and corresponding access tokens to obtain service resources or issue control information; guarantee the characteristics of data domain storage.

Description

technical field [0001] The invention belongs to the technical field of computer applications, and in particular relates to an application cross-domain access method based on the multi-domain collaborative architecture of the Internet of Things. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: As another major breakthrough in information technology after electronic computers, communication technology and the Internet, the Internet of Things has become a key technology leading the development of modern science and technology. The development of intelligent sensing devices in the sensing layer of the Internet of Things has also further driven the development of software in its application layer. In order to shield the differences in the underlying software and improve the reusability of software in different hardware environments, the design of modular software has become a hot spot in application layer software ...

AI Technical Summary

Problems solved by technology

[0003] In summary, the problems in the prior art are: The caching characteristics of traditional CDN content distribution do not match the multi-domain characteristics of the Internet of Things

Internet of Things application user requests often specify access to a certain domain. If the traditional CDN still distributes requests according to the principle of proximity, the CDN request distribution strategy cannot meet the multi-domain characteristics of the Internet of Things.

[0005] 2. The types and sizes of data in each domain are complex

However, in the IoT multi-domain scenario, the resources of each domain are controlled by the domain administrators, and the central domain management lacks control over them.
