The definition of a carrier-managed SD-WAN Service according to Vertical Systems is a carrier-grade offering for business customers that is managed by a network operator, uses an SDN architecture, enables dynamic customer edge site connectivity and provides centralised network control and visibility end-to-end. This is does not include DIY SD-Wan solutions purchased from an SD-WAN technology supplier, system integrator or cloud provider.
In 2018, eight companies topped the annual US carrier-managed SD-WAN Services leaderboard in rank order these are: AT&T, Hughes, Verizon, Windstream, CenturyLink, Aryaka, Fusion and Comcast. These companies had the highest market shares of installed carrier-managed SD-WAN customer sites in the US as of year-end 2018.
“Providers in the carrier-managed segment of the SD-WAN market have emerged as the best choice for delivering large scale, complex and resilient SD-WAN services end-to-end,” said Rick Malone, principal of Vertical Systems Group, at the time. “We believe that network operators with deep experience in MPLS, Ethernet and IP are most favourably positioned to support enterprise customers as they transition their networks to SDN.”
Companies with the next largest market shares in this segment were cited in the Challenge Tier. The following six companies attained a Challenge Tier citation for 2018, which in alphabetical order are Bigleaf, GTT, Masergy, Meriplex, Sprint and TPx.
