Energy Efficiency through VM Redistribution in Telecommunication Nodes

Energy efficiency is one of the key factors impacting the green behavior and operational expenses of telecommunication core network operations. This thesis study is aimed for finding out possible technique to reduce energy consumption in telecommunication infrastructure nodes. The control plane of a telecommunication node is a custom built high performance cluster which consists of multiple General Purpose Processors interconnected by high-speed and low-latency network. Due to application configurations in particular GPP unit and redundancy issues, energy usage is not optimal. The motivation of this study is to gain elastic behavior within the control plane cluster to reduce energy consumption. The elastic behavior scales down and wakes up certain GPP units depending on traffic load situations. The traffic load situation triggers VM migration in the control plane on demand. This thesis study shows that imposing the elastic behavior through VM mobility within the cluster can be an efficient approach to significantly reduce energy consumption in control plane of cluster-based telecommunication infrastructure nodes without interrupting performance/throughput.
