Where have all the global network aggregators gone?

One of the key selling points of SD-WAN is the ability to use a variety of network transport options. Enterprises can select MPLS, dedicated Internet access, business broadband, or wireless broadband, for example – whatever makes the most sense, technically and economically, for each site that needs connectivity. Cultivating a mix of suppliers can allow enterprises to significantly reduce transport costs as well as improve the flexibility of their networks. The growth in SD-WAN deployments over the last four or five years created a sweet spot for Internet transport aggregators, which, frankly, had struggled to break into the enterprise market when it was dominated by traditional MPLS providers.
