SD-WAN Roundup: Market Saturation Opens the Door for Partner Opportunity


… actually review the product and take a look at it.”

Kleyman says SD-WAN is the answer to the question of how businesses can better control their internet services and WAN while saving money and time.

“When an organization gains control of [its] wide area network, they can all of a sudden make really some cool decisions. They can restructure the MPLS contract and their Ethernet services. They can opt for less-expensive carrier services to create redundancy for remote locations. They can control things like application-bonding to make sure it’s resilient and delivered much more quickly,” he said. “This kind of architecture is absolutely conducive to today’s industry. More bandwidth, more cloud, more users, more devices connecting, and simply more requests for wide area networking resources. Without this kind of technology, you’d see organizations continue to pay more and more dollars for an environment they have less and less control over.”

A new vendor entered SD-WAN last week in the form of Zayo Group. The communications infrastructure provider announced an offering that expands its WAN portfolio. The company already provides in the areas of dark fiber, transport services and WAN, and that makes SD-WAN a “logical extension,” according to Michael Strople, president of Zayo Enterprise Networks.

Strople says hybrid WAN will be a main driver of SD-WAN adoption in the upcoming years. He says businesses want flexibility, choice and the ability to steer their traffic.

“The hybrid WAN is bridging disparate access types together. The straightforward example is: I might use a IP-VPN connection on a WAN today, but I might want to blend that together. So at each site I might use IP-VPN and marry that also with an internet WAN connection, and I could load-share those to increase my availability of redundancy, where I might want to put some traffic across only the IP-VPN and some traffic only across the internet connection and I might want to have diversity of providers,” Strople said.

Technology from Versa Networks is powering the offering, which comes in advanced and basic management options. Other providers may contribute to it in the future.

Stephen Fisher, chief technology officer of Zayo Enterprise Networks, illustrates two use cases for the SD-WAN. One is a business that has Zayo-connected fiber, many bandwidth requirements and offices in regions that require extended Type II services. Another is a an enterprise that allows its employees to watch multimedia such as Netflix during their breaks but needs to prioritize business-related communications over the Netflix traffic. The SD-WAN allows that prioritization.

“That may be the perfect example of a customer that has a classic IP-VPN, dedicated WAN and then a large amount of traffic that they want to send off to an internet directly and not consume the WAN traffic. They would have two uplinks – one an Internet uplink, one a WAN uplink – and they could direct traffic to one direction or the other for those specific applications and the bandwidth requirements of those applications,” Fisher said.

Fisher says he sees customers evolving their …
