Multi-Cloud Open Radio Access Network Resource Manager and Orchestrator

The Open Radio Access Network (O-RAN) represents a significant advancement in mobile network technology. Combining private and public cloud resources, service-based management and orchestration of Virtualized Network Functions (VNFs) in O-RANs enable operators to address diverse subscriber requirements and sustain network operations even under adverse conditions. Open standardized O-RAN interfaces make the composition of Radio Access Networks more flexible, allowing the integrated use of VNF and service software from different vendors. However, regarding infrastructure management, the absence of API standardization among Cloud Service Providers (CSPs) associated with the variety of existing cloud technologies hinders the implementation of multi-cloud approaches. In this work, we present a solution that provides a unified interface for managing and orchestrating Open Radio Access Networks across cloud sites from different CSPs.

Unified Fog Computing Architecture Integrating O-RAN, MEC, and OneM2M

Fifth-generation (5G) networks and the Internet of Things (IoT) demand unprecedented levels of scalability and ultra-low latency. Addressing these needs requires not only advanced radio technologies but also a cohesive integration of diverse architectural standards. In this paper, we present a unified fog computing framework inspired by ETSI and OneM2M technical literature that merges the Open Radio Access Network (O-RAN) architecture, Multi-Access Edge Computing (MEC), and the OneM2M IoT standard. This approach enables real-time resource allocation, reduces end-to-end latency, alleviates network congestion, and streamlines interoperability across heterogeneous deployments. Through a simulated testbed, we demonstrate how MEC and OneM2M elements can use near-RT RIC intel to optimize service delivery. The results highlight the feasibility and potential performance gains of an integrated O-RAN-MEC-OneM2M environment, paving the way for more robust, scalable, and efficient 5G IoT solutions.
