Summary

Recommendation ITU-T Y.4453 addresses the concept of the adaptive software framework (ASF), identifies high-level requirements and provides a reference functional architecture for Internet of things (IoT) devices. The ASF is a framework to manage and control adaptive IoT applications in real-time and in a dynamic way and enables optimal quality of service (QoS) performance. The adaptive IoT application is an IoT application that changes performance by altering system resource allocation (e.g., the number of central processing unit (CPU) cores, graphics processing unit (GPU) utilization, network bandwidth, etc.). Therefore, the ASF can provide optimal working of applications on IoT devices. The ASF is based on the IoT reference model described in Recommendation ITU‑T Y.4000.
