On-demand application-driven network slicing

A system, comprising:

• a radio-based network including a radio access network and associated core network, wherein an application utilizes a network slice of the radio-based network to send and/or receive network traffic;
• a network slice allocation service configured to dynamically modify the network slice in response to application programming interface (API) requests from the application;
• and
• at least one computing device implementing the application, wherein the application is configured to at least:
• determine that the network slice does not meet a quality-of-service requirement including at least one of:
• a minimum bandwidth requirement or a minimum latency requirement;
• send a first API request that causes the network slice allocation service to reserve additional capacity for the network slice for the application in the radio-based network, the network slice providing the quality-of-service requirement;
• use the network slice to send and/or receive the network traffic;
• determine that the network slice exceeds the quality-of-service requirement;
• and
• send a second API request to the network slice allocation service to release at least a portion of capacity reserved for the network slice.
