As Important as SD-WAN is, It Will Remain a Niche Market for Service Providers

With the caveat that it likely represents the future of most enterprise long-haul transport revenues, the SD-WAN market is a specialist segment of the market, very much akin to unified communications. It is important for enterprises and suppliers to enterprises.


It is a fundamental product for sellers of long-haul enterprise networking capacity. But the global SD-WAN market is rather a smallish part of total spending on public network communications services.


As for how big a revenue stream SD-WAN might eventually represent, just assume it displaces most of the present MPLS market.

For long-haul business connectivity providers, SD-WAN is as important as MPLS is, and private line used to be. As the humorous adage goes, "it may be a one-trick pony, but it's a good trick."
