“…The proposal makes use of this queue scheduling mechanism to provide support for multiple tenants sharing the DC network. Related to this idea, in [45] it is stated that, in a multi-tenant cloud, customers may request/build a virtualized network, but bandwidth guarantees are not provided. Therefore, the authors propose a way to provide those guarantees that involves a novel virtual network to physical network mapping.…”

OpenFlow is a network device management and monitoring protocol, as well as a switch specification, that has enabled research, experimentation and deployment of software-defined networks in general, and data center networks in particular. In this review, after describing the particularities of data center networks and OpenFlow technology, a collection of recent research papers integrating both topics is analyzed. The collection of proposals made by the authors whose research is reviewed is very broad. Most focus on traffic engineering, load balancing, congestion reduction and related topics, with the goal of optimizing data transfer by using all available resources. Other works focus on issues related to the multi-tenancy nature of these large networks, monitoring them, improving their security or modifying switch architecture specifically for data center networks. Overall, we have a panoramic view of the issues related to data center networking and the flexibility OpenFlow provides to help solve them.INDEX TERMS Software defined networking, OpenFlow, datacenter, interconnection networks.

Data centers consume significant amounts of energy, contributing indirectly to environmental pollution through greenhouse gas emissions during electricity generation. According to the Natural Resources Defense Council, information and communication technologies and networks account for roughly 10% of global energy consumption. Reducing power consumption in Data Center Networks (DCNs) is crucial, especially given that many data center components operate at full capacity even under low traffic conditions, resulting in high costs for both service providers and consumers. Current solutions often prioritize power optimization without considering Quality of Service (QoS). Services such as video streaming and Voice over IP (VoIP) are particularly sensitive to loss or delay and require QoS to be maintained below certain thresholds. This paper introduces a novel framework called QoS-Aware Power-Optimized Path Selection (Q-PoPS) for software-defined DCNs. The objective of Q-PoPS is to minimize DCN power consumption while ensuring that an acceptable QoS is provided, meeting the requirements of DCN services. This paper describes the implementation of a prototype for the Q-PoPS framework that leverages the POX Software-Defined Networking (SDN) controller. The performance of the prototype is evaluated using the Mininet emulator. Our findings demonstrate the performance of the proposed Q-PoPS algorithm in three scenarios. Best-case: Enhancing real-time traffic protocol quality without increasing power consumption. midrange-case: Replacing bottleneck links while preserving real-time traffic quality. Worst-case: Identifying new paths that may increase power consumption but maintain real-time traffic quality. This paper underscores the need for a holistic approach to DCN management, optimizing both power consumption and QoS for critical real-time applications. We present the Q-PoPS framework as evidence that such an approach is achievable.
