Summary: The rapid advancement of networking and computing technologies has brought new challenges in the provision and management of network services. SDN and NFV technologies, along with the use of knowledge-based systems, are effective solutions. However, the lack of a simulation framework with knowledge concept has been a gap in the NFV and SDN field. In this paper, a highly extensible, interoperable, and scalable simulation framework for developing knowledge-based methods is proposed. Additionally, a new auto-scaling method based on machine learning is proposed and simulated, showing its effectiveness and efficiency in resource prediction and VNF auto-scaling.

Summary: Emerging network-softwarization technologies, such as software-defined networking and network function virtualization, have significant roles in 5G communication and future networks. One of the critical challenges is the appropriate placement of virtual network functions (VNFs) in softwarized networks. This study focuses on the joint optimization problem of VNF Placement, CPU Allocation, and flow Routing (VNFPAR) in scenarios with dynamically changing VNF traffic. The proposed algorithms, including an optimal algorithm and heuristic algorithms, demonstrate their effectiveness in solving VNFPAR problems and achieving a tradeoff between solution quality and execution time.

Summary: Network Function Virtualization (NFV) is an architecture that separates software from hardware using virtualization technology. One of the challenges in NFV is managing the resources of virtualized network functions (VNFs). Due to the dynamic nature of NFV, resource allocation to VNFs needs to be adjusted based on incoming traffic variations. This paper analyzes and compares three machine learning algorithms, Support Vector Regression (SVR), Decision Tree (DT), and k-Nearest Neighbor (KNN), in terms of resource prediction. The results show that all three algorithms achieve an error less than one in predicting resources, with SVR having a longer execution time compared to the other two algorithms.

Summary: This article proposes a dynamic heterogeneous redundancy (DHR) scheme for connected automated vehicles (CAVs) to achieve both safety and security in the presence of functional failures or cyberattacks. The DHR architecture, employing multiple heterogeneous executors with the same function, ensures functional safety by providing redundancy and enhances security by detecting abnormal executors caused by cyberattacks. Test results on an automated bus demonstrate the effectiveness of the proposed DHR in enhancing both safety and security for CAVs.

Summary: In this paper, the authors discuss linear-quadratic mean-field social control problems for a specific class of stochastic systems with ordinary and delay control inputs. They introduce a stabilization problem using a memoryless static output feedback (SOF) strategy and use the guaranteed cost control theory to minimize the upper bound of the cost function. The study reveals that minimizing the upper bound of the cost function is not achievable with only a delay control input. They also prove the impossibility of implementing a mean-field SOF strategy and establish the necessary conditions for sub-optimality using stochastic cross-coupled matrix equations (SCCMEs) and the Karush-Kuhn-Tucker condition. Lastly, the authors investigate the performance and usefulness of their proposed strategy using an order-reduced scheme based on the direct method.
