Effective Resource Management in SDN Enabled Data Center Network Based on Traffic Demand

Abstract

Software-defined networking (SDN) changes the way forwarding devices works and makes data center network simplified and efficient to work. Energy is the main driving force behind the activity of the data center network. The network elements that are in low load condition can be shifted in switch-OFF condition after migrating their active traffic on some other element. This traffic analysis-based energy-saving approach will increase the overall utilization of the system. This paper presents a switch-ON/OFF procedure along with the rerouting procedure to achieve the desired activity. The modules are tested over some wellknown data center topologies, such as Fat-Tree and Bcube. The simulation study is carried out with the classical SDN controller instances, e.g., OpenDayLight, POX, Beacon, and NOX. The results are compared with some similar energy-efficient data center approaches, such as MNLR DCN and WDM Optical Switched DCN. The proposed approach presents an enhancement of 77%, 37%, and 63% in achieved energy saving, average round trip delay, and average bandwidth utilization, respectively.

“…However, more targets, such as energy-saving scenarios, could be implemented in the future. Furthermore, effective resource management based on traffic demand, as depicted in [54], may also be adopted.…”

Hybrid SDN evolution: A comprehensive survey of the state-of-the-art

“…Besides, a comparison between both architectures and SDN controllers ,ONOS [95] and POX [259], is driven at the end of the article (Section IV) which demonstrates that ScalCon outperforms all the previously mentioned schemes in terms of path computation latency, transmission overhead, and end-to-end delay. Paliwal et al [256] have created an energy efficient resource management technique intended for those DCs where the traffic patterns are highly correlated to the traffic demand over sets of operational hours. This approach aims at enhancing the advantages of combining hSDN with MPLS to conform real-time dynamic provision of network elements and energy saving in the DCN (see Figure 14 for the architectural view).…”

“…As shown in section 6.2 and in Table 7, there has been a lot of research on this topic for pure SDN but it is still an innovative research area that needs to analyze the energy efficiency management in DCNs with hSDN. hSDN cloud-native proposals with a focus in energy efficiency [256] demonstrate the potential within this combination of technologies, however these approaches are conditioned to a limited range of DCNs topology types. -hSDN and MEC-based architectures.…”

Priority-Based Bandwidth Management in Virtualized Software-Defined Networks

“…SDN allows the designers to easily implement dynamic and adaptable QoS control solutions for both wired and wireless networks [30,31]. Several works proposed resource management approaches suitable for various scenarios, such as data centers [32], 5G SDN-based networks [33], Industrial Wireless Sensor Networks [34,35], and IoT-enabled smart homes [36]. Other notable software-defined bandwidth management mechanisms were proposed in [37][38][39][40].…”
