JSON – JavaScript Object Notation
(JSON) is a standard text-based format for representing structured data based on JavaScript object syntax. It is commonly used for transmitting data in web applications (e.g., sending some data from the server to the client, so it can be displayed on a web page, or vice versa). JSON plays a big role in the new 5G Core.
The 5G core network will be based on what is called “Service-Based Architecture” (SBA), and uses the new web protocol, HTTP/2 from IETF, REST (REpresentational State Transfer), JSON , and OpenAPI as the interface definition language.
