Identifier resolution method and apparatus for the internet of things

An identifier resolution method for the Internet of Things, which is based on an identifier resolution architecture for the Internet of Things, wherein the identifier resolution architecture for the Internet of Things comprises:

• an access layer, a conversion layer and an identifier root service layer, wherein
• the access layer is configured to access at least one identifier resolution system;
• the conversion layer is at least configured for conversion between an identifier and a domain name;
• and
• the identifier root service layer comprises an alliance chain and an identifier root service for the Internet of Things, wherein the alliance chain comprises at least one preselected node and at least one data distribution node;
• each preselected node separately stores a different type of root data, and the data distribution node is configured to synchronize the root data in each preselected node to the identifier root service for the Internet of Things;
• wherein the identifier resolution method comprises:
• obtaining, by the conversion layer, a to-be-resolved identifier from an identifier resolution request, and determining whether the to-be-resolved identifier can be converted, in response to receiving the identifier resolution request;
• converting the to-be-resolved identifier into a domain name, when the to-be-resolved identifier can be converted;
• requesting, by the conversion layer, domain name root data corresponding to the domain name from the identifier root service for the Internet of Things;
• and
• obtaining, by the conversion layer, a domain name resolution system from the access layer upon receiving the domain name root data returned by the identifier root service for the Internet of Things, and resolving the domain name based on the domain name root data and the domain name resolution system.
