A Distributed Green Networking Approach for Data Center Networks
Green networking for data center network is becoming a critical issue due to the rapid growth of energy consumption. Most of existing green networking approaches are in a centralized-control manner, which have a scalability issue. Existing distributed approaches are scalable, but consume too much network resource, including computing and network bandwidth. In this letter, we propose a distributed green networking approach for data center network, called distributed green networking approach (DGNA). In our approach, we propose an energy-efficient flow scheduling mechanism, which requires less computing and much less network bandwidth compared with traditional approaches. In DGNA, two shut-off algorithms are proposed to shut-off links with different efficiency and complexity. Simulation shows that DGNA sends less than 0.9% of link state advertisements compared with a traditional approach.
