Impact of CPU Resource Allocation on vRAN Performance in O-Cloud
The need for mobile operators to have an infrastructure capable of handling ever-increasing traffic and supporting the development of more demanding services at lower costs has given rise to the O-RAN paradigm. This organization proposes a disaggregated and virtualized Radio Access Network (vRAN) running on commodity servers, moving away from traditional monolithic network environments. In this context, managing the available computing resources at the host machine is key to meeting network requirements without wasting resources. This work aims to evaluate the impact of computational and radio resources on network performance under different radio configurations. The results prove that misallocating resources to vRAN instances can lead to network performance degradation and that additional dedicated resources do not always translate into better performance.
