SBI interface 5G

In the meeting they decided to employ the new web protocol , HTTP/2 from IETF, design interfaces according to the REpresentational State Transfer (REST) principle where possible, and use JavaScript Object Notation (JSON) as a data format and OpenAPI as the interface definition language.

The deployment of 5G cellular technologies will accelerate the evolution of Programmable Telecom Application Program Interfaces (APIs). These APIs will need to be enhanced to support the 5G features and services being rolled out.

REST Principles. Applying REST to 5G: SBI Protocol Stack. HTTP/2 .

Currently, however, the Service-Based Architecture employs a centralized discovery framework that leverages a NF Repository Function (NRF) . The NRF maintains a record of available NF instances and their supported services.

At 5 milliseconds, current DNS latency is too high to support many 5G applications . For example, in 5G deployments, AR/ VR, gaming, connected cars, and telesurgery will require end to-end latency of 1-10 milliseconds. Clearly, current DNS latency is unacceptable.
