Segment Routing Green Spine Switch Management System for DCN

Abstract It is without a doubt that the data center is the core of most IT industries, providing services to billions of users today. Furthermore, due to the exponential increase of information and services from datacenters, it is projected that a 14.1 zeta bits of bandwidth would be needed to meet the current demands of data by the end of 2020 in USA data centers alone. This requires a tremendous amount of energy to run those data centers. To reduce the energy consumption of a data center, this thesis approaches this problem by utilizing Segment Routing and Traffic Engineering to have an efficient the bandwidth usage. The proposed approach makes it possible to deactivate spine switches and links on the data center networks, which results in energy savings. The experimental results yielded up approximately 78% energy savings, whilst maintaining an average similar traffic performance.
