Bringing agility and scalability to telecommunications, software-defined networking is the radical transformation that will enable today’s explosive data growth to continue.
With video conferencing, dynamic cloud workloads and unified communications, network traffic is growing at an astonishing rate. Data traffic on the AT&T wireless network grew more than 150,000 per cent between 2007 and 2015 and this is only the beginning.
We expect new applications, like the Internet of Things, 4K video, virtual reality and augmented reality, to push bandwidth demand even higher in coming years.
This explosion of data is already outpacing the capacity of the traditional telecommunications network. For more than a century, telecoms networks have been based on specialized, single-purpose equipment, including routers, switches and other custom-built network devices.
To add capacity, we had to add more equipment. This worked well when the majority of data was voice traffic, which increased gradually and predictably. Today, however, we simply cannot build the physical infrastructure quickly enough. We need a new way to build and manage our data networks.
