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. The preferred data center network (DCN) architecture used for this platform is the 2-tier leaf-spine topology, which is not only energy efficient but has a good performance metrics. 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 would require a tremendous amount of energy to run those data centers.Hence, in recent years there is more focus on reducing the energy consumption in a data center. In trying to reduce the energy consumption of a data center, this thesis approaches the problem by utilizing Segment Routing-Traffic Engineering, and other power algorithms for an efficient DCN. The proposed approach makes it possible to deactivate spine switches and links on the data center networks, which results in energy savings. Our experimental results yielded an approximate of 80% in energy savings of the spine switches consumption whilst maintaining an average similar traffic performance.iii
