This paper serves as a foundation for researchers and practitioners to explore the key concepts, primary applications, and potential impacts of xApps in the open radio access network (O-RAN) architecture. We provide background information and examples related to xApps and discuss several fundamental concepts to familia...

Dynamic resource assignment, the real-time allocation of task streams to heterogeneous processing nodes, is the backbone of modern computing infrastructure. While learning-based schedulers excel in research, industrial deployments still rely on hand-written rules that operators can read, audit, and execute within tight...

The evolution toward disaggregated, cloud-native, and multi-vendor architectures, as demonstrated by the open radio access network (O-RAN), together with the stringent performance requirements of sixth-generation (6G) networks, necessitates advanced transport network (TN) management and orchestration (M&O). Such capabi...
