A Novel Sustainable Bandwidth Allocation Strategy for Multiple Service Migration in 5G/6G Edge Computing

Multi-containerized applications are becoming more common. Modern mobile Internet-of-Things applications, e.g., augmented reality and online gaming, have increased the need for ultra-low and real-time application responses. Edge computing is a solution for decreasing response times by relocating services closer to users. Migrating multiple services in this environment is unavoidable, given user mobility and load balancing. We utilize the MiGrror migration method, to propose a novel strategy for increasing bandwidth for short critical periods instead of maintaining increased bandwidth throughout the entire migration process. Our novel strategy drastically reduces downtime and migration time while enhancing bandwidth utilization by freeing up additional bandwidth during migration, which increases bandwidth availability for other services. The findings indicate that, even without using additional bandwidth, adjusting the timing of a bandwidth increase/decrease for services improves performance. The results are comparable to increasing the bandwidth for the entire migration duration with equivalent bandwidth consumption. Additionally, this study demonstrates that the proposed strategy is more sustainable than when using the original bandwidth, which results in less data transfer.
