BDA-based Slice Admission and Edge-Assisted Congestion Control for Beyond 5G and 6G Networks to boost Infrastructure Provider Profits

Abstract

Research and Development (R&D) efforts and standardization processes for 6th Generation (6G) networking technologies are now on worldwide. Compared to 5G, the data load on 6G will be substantially higher. When developing 6G network architectures, it is crucial to consider the constrained resources of Mobile Network Operators (MNOs) and the anticipated significant demand for network slicing to provide cloud services. Slice requests are granted or denied based on their influence on the Infrastructure Provider's income and the availability of resources. The profit of an Infrastructure Provider (InP) is directly correlated with the acceptance of requests, since it generates income for each resource provided. However, the probability of slice degradation also increases as the resource load grows. Therefore, the InP is obligated to bear penalties in the event that quality is overlooked. The study focuses on the slice admission policy of the SDN-based architecture, which utilizes BDA and a congestion avoidance mechanism. The objective is to optimize the revenue of infrastructure providers while maintaining high service quality.
