Narrowing the view to the three types of SD-WAN architecture HITTING THE TARGET By Martin Vilaboy VIRTUAL REALITIES SD-WAN is safely past its “peak of overinflated expectations,” and yet still a good majority of the dollars that eventually will be spent on transitioning private networks to software defined has yet to come. According to TeleGeography’s deep dive into the wide area network market, SD-WAN accounts for just 5 percent of WAN spending by global enterprises, accounting for about $3 billion. Techaisle surveys, meanwhile, counted 10 percent of SMBs as users of an SD-WAN, while Aryaka reported a similar 11 percent adoption in its most recent “Global State of the WAN” survey. That’s the same percentage that reported to “deploying now.” Indeed, MPLS still dominates global enterprise spending. According to TeleGeography’s figures, MPLS is worth $17 billion and maintains 29 percent of the global WAN market. “Together, MPLS and access loops connecting to MPLS POPs account for 60 percent of the market for large multinational enterprise WANs,” said the research firm. Altogether, MPLS and DIA port charges remain the largest contributor at $33.6 billion, followed by local access charges at $22.1 billion. 22 CHANNELV ISION | JULY - AUGUST 2022
