Reducing energy consumption in SDN-based data center networks through flow consolidation strategies

摘要

The data exchanged over networks has grown over the years, and is expected to grow further moving forward. This has led to increases in the required bandwidth, storage, and computing power of the entities involved. Due to this, present-day networks have moved to cloud environments to achieve better scalability and reduce infrastructure costs. Cloud service providers host their cloud environments on large-scale data centers, which process huge volumes of data. Processing such huge volumes of data requires an enormous amount of energy, leading to increased carbon footprints and thus environmental impacts. Researchers are now looking for ways to reduce energy consumption in data center networks (DCNs).
