AI Technical Summary
In the reconstruction of the service function chain of IoT devices, changes in resource demand lead to a decline in network service quality. Existing reconstruction methods are ineffective and cannot effectively cope with the changes in network traffic caused by high user mobility.
By predicting user historical trajectory information and virtual network function resource usage information, an optimization function is established to predict end-to-end latency and resource requirements, triggering service function chain reconstruction in advance, migrating virtual network functions to suitable edge servers, and optimizing the migration path to minimize reconstruction costs and latency.
It enables the early prediction and optimization of service function chain reconfiguration in situations of high user mobility, providing consistent and high-quality network services, reducing reconfiguration costs, and improving network performance and availability.
