Special Issue Information

Dear Colleagues,

Networking and computing are undergoing a major shift toward cloud computing.

Cloud computing is now being adopted by end-user devices on wired and wireless networks such as "fog computing". With fog computing, cloud capability is extended through nodes and IoT gateways to provide compute, storage, and networking services. Technology uses multiple endpoints to process data closer to the end user, which is one of the major advantages. A network can be viewed as an overall picture based on the results of numerous data points, which is both more scalable and more accurate than edge computing.

In future technological developments such as 5G networks and the Internet of Things (IoT), fog computing (FC) may be a promising addition to Internet architecture. A large number of sensors generate continuous sensory information via these advanced technologies that are integrated into Internet architectures.

Special emphasis is placed on identifying the required services and network-oriented features required to build a future enterprise network using fog computing and cloud computing as enablers for 5G networks. Potential topics include, but are not limited to, the following:

  • network storage,
  • Internet of Things (IoT);
  • heterogeneous 5G mobile services;
  • fog computing;
  • cognitive radio networks;
  • software-defined networking;
  • mobile cloud computing.

Cloud-based Radio Access Network (Cloud-RAN) leverages virtualization to enable the coexistence of multiple virtual Base Band Units (vBBUs) with collocated workloads on a single edge computer, aiming for economic and operational efficiency. However, this coexistence can cause performance degradation in vBBUs due to resource contention. In this paper, we conduct an empirical analysis of vBBU performance on a Linux RT-Kernel, highlighting the impact of resource sharing with user-space tasks and Kernel threads. Furthermore, we evaluate CPU management strategies such as CPU affinity and CPU isolation as potential solutions to these performance challenges. Our results highlight that the implementation of CPU affinity can significantly reduce throughput variability by up to 40%, decrease vBBU’s NACK ratios, and reduce vBBU scheduling latency within the Linux RT-Kernel. Collectively, these findings underscore the potential of CPU management strategies to enhance vBBU performance in Cloud-RAN environments, enabling more efficient and stable network operations. The paper concludes with a discussion on the efficient realization of Cloud-RAN, elucidating the benefits of implementing proposed CPU affinity allocations. The demonstrated enhancements, including reduced scheduling latency and improved end-to-end throughput, affirm the practicality and efficacy of the proposed strategies for optimizing Cloud-RAN deployments.
