: Handling today's [[big data]] requires massive parallel processing on thousands of servers, all of which need direct connections to each other. The rise of these large [[data set]]s is fueling a constant demand for additional network capacity in the data center. Operators of hyperscale data center networks face the daunting task of scaling the network to previously unimaginable size, maintaining any-to-any connectivity within a limited budget.<ref>{{Cite journal|last1=Vicentini|first1=Cleverton|last2=Santin|first2=Altair|last3=Viegas|first3=Eduardo|last4=Abreu|first4=Vilmar|date=January 2019|title=SDN-based and multitenant-aware resource provisioning mechanism for cloud-based big data streaming|journal=Journal of Network and Computer Applications|volume=126|pages=133–149|doi=10.1016/j.jnca.2018.11.005|s2cid=57941895}}</ref><!--[[User:Kvng/RTH]]-->
; Energy use onin large datacentersdata centers
: As [[Internet of Thingsthings]], [[cloud computing]] and [[SaaS]] emerged, the need for larger datacentersdata centers has increased the energy consumption of those facilities. Many researchers have improved SDN's [[Efficient energy use|energy efficiency]] applying existing routing techniques to dynamically adjust the network data plane to save energy.<ref>{{cite journal |last1=Assefa |first1=Beakal Gizachew |last2=Özkasap |first2=Öznur |title=RESDN: A Novel Metric and Method for Energy Efficient Routing in Software Defined Networks |journal=IEEE Transactions on Network and Service Management |date=June 2020 |volume=17 |issue=2 |pages=736–749 |doi=10.1109/TNSM.2020.2973621 |url=https://doi.org/10.1109/TNSM.2020.2973621|arxiv=1905.12219 |s2cid=199442001 }}</ref> Also techniques to improve control plane energy efficiency are being researched.<ref>{{cite journal |last1=Oliveira |first1=Tadeu F. |last2=Xavier-de-Souza |first2=Samuel |last3=Silveira |first3=Luiz F. |title=Improving Energy Efficiency on SDN Control-Plane Using Multi-Core Controllers |journal=Energies |date=May 2021 |volume=14 |issue=11 |pages=3161 |doi=10.3390/en14113161 |language=en|doi-access=free }}</ref><!--[[User:Kvng/RTH]]-->
