How SDN Could Transform Network Performance

  • submit to reddit

IBM's Charles Ferland says that SDN and open source technologies like OpenFlow could change the way businesses do networking in their data centers, and could revolutionize networking performance.

Ferland explains that SDN stands to harmonize networking with business needs by allowing businesses to scale their networking requirements to business needs in real time. Traditional networking infrastructure is expensive to setup and maintain, but in the same way that cloud computing made storage and hosting cheap and scalable, SDN stands to eliminate a significant amount of the setup cost for a business's networking infrastructure.

Traditional networking requires businesses to add or upgrade expensive hardware in their networking infrastructure when the business's needs for networking performance change. With SDN, scaling up network infrastructure is as easy as installing an app, and the infrastructure can just as easily be scaled-down if networking needs lessen.
