Software-defined networks offer greater control to IT departments

Considerations for adoption
IT departments can better assess the value of SDN after experimenting with the technology. Data Center Knowledge recommends that tech professionals create experimental test networks to learn the nuances of software-defined networks and evaluate the potential for the solution to benefit their network infrastructure. Bandwidth challenges, for example, can arise as IT departments convert their network to a SDN platform. Budget proposals for a switch to SDN can leverage the fiber to Ethernet connectors to minimize spending on costly cables by mixing copper and fiber solutions.

Another major consideration for IT departments is the initial task of securing a software-defined network. The central controller will automate a large share of network security configurations, requiring IT departments to be extremely active in identifying and dealing with potential security breaches. Betanews.com notes that some companies have secured their networks by applying software-defined network solutions over a wireless LAN controller. The move helped to improve network visibility and minimize the required retraining of staff. Additional solutions for securing SDN infrastructures will appear as the technology becomes more mainstream.
