Branch office links, big bandwidth needs drive SD-WAN evolution

SD-WAN vendor VeloCloud to offer a managed WAN-SD service.

Beyond the bandwidth, security of WAN connections is an issue that SD-WAN can address experts say.

“The ability to segment parts of the network end-to-end, support encryption and authentication are all key components of SD-WAN services, “ said Ramesh Prabagaran, vice president of product management at Viptela. Policies to manage specific segments can then be applied to control access particular locations. Customers can also more easily segment a portion of the network should an attack occur. Such features are particularly key to financial and healthcare enterprises, Prabagaran said.

Better automation features will also be a key driver of SD-WAN deployment. For example Verizon envisions its managed SD-WAN service will be able to detect when it needs more bandwidth and automatically turn it up. It will be able to back it off if necessary said Viraj Parekh, director of product and new business initiatives at Verizon. “We expect to be able to do that by the end of the year,” he said.
