Wide-area networks using SDN achieve greater agility and flexibility. Read what network administrators should consider as they plan to deploy SD-WAN.
One of the biggest upheavals inside enterprise systems now involves networking. Old-school hardwiring is quickly being overtaken by new-generation, software-defined networks. For the vast number of enterprises of all sizes, this new world of software-defined networking (SDN) is attractive for a number of reasons—manageability and cost containment being chief among them. Software-defined wide-area networks (WANs) have roots in SDN, the underlying principle of which is to abstract the network hardware and transport characteristics from the applications that use the network.
