In today’s world, where everyone has a cell phone, a tablet, a laptop and maybe a few other smart devices, it’s necessary to be flexible to support the networking needs of your constituents and avoid a slow, overloaded network. When the ebb and flow of the day occurs, where people congregate in different but predictable areas throughout the day, how does the network respond to the variation in traffic over time? When coupled with the fact that the administration and maintenance costs of the network are higher than the equipment and environmental costs combined, many are turning to software-defined networking. SDN reduces those costs and allows network administrators to easily respond to the real-time variations in network traffic in order to increase customer satisfaction and retention.
SDN is not only in the lab and academia, network vendors are getting more involved and opening up their products to enable the interoperability necessary for a full SDN deployment. Cisco has made their physical boxes more programmable, with an open API. HP has created an SDN app store, believing it’s all about the software, to quickly and easily deploy SDN services. Physical switch vendors have also begun to make their devices more programmable through open APIs. All of this makes managing networking traffic substantially easier.
Market transitions are never quick and SDN will be no different. Steady, substantial progress has been made and more is coming. It takes time and investment in new hardware and software. However, with SDN implemented, administrating and maintaining the network will be easier, faster and — most importantly — cheaper. Our solutions can help make the transition smoother by supporting the network technology of both today and tomorrow and the flexibility to support either, in both a mixed and a hybrid deployment model.
