Abstract

Multiple Access Edge Computing (MEC) and Network Function Virtualization (NFV) are key-technologies in the Fifth Generation of Mobile Networks (5G) to support services such as Ultra-Reliable and Low Latency Communication (URLLC) and Enhanced Mobile Broadband (eMBB). However, ensuring the coexistence of these services poses challenges, particularly in dynamic resource allocation within the MEC-NFV domain. This paper presents a Continuous Time Markov Chain (CTMC)based model to analyze the impact of dynamic resource allocation on both URLLC and eMBB services in an MEC-NFV environment. The analysis considers factors such as virtualization overhead, virtual resource failures, and varying numbers of containers and buffer sizes. The results indicate that availability, response time, and energy consumption are strongly influenced by the number of containers, while buffer size primarily affects response times.
