Software-defined wide-area networking (SD-WAN), virtual customer premises equipment (vCPE) and universal customer premises equipment (uCPE) are critical elements in the transformation of the WAN marketplace. These last 12 months have seen the focus in the SD-WAN market shift from vCPEs and NFV in the service provider market to SD-WAN solutions in the enterprise.
Within enterprises, growing dependence on cloud services (IaaS, PaaS, SaaS), increased demand for bandwidth at the edge, as well as security and compliance requirements have driven organizations to look for new solutions for their WANs. The traditional approach of proprietary integrated software-hardware appliances combined with one-off box-by-box configuration can no longer meet the needs of today’s enterprises.
SD-WANs, leveraging SDN (software-defined networking) principles, and sporting centralized cloud controls and a combination of WAN technologies (layer 3, layer 4-7) under one umbrella, fit the new enterprise requirements well. In addition to the cloud networking vendors who have rebranded themselves under the SD-WAN moniker, other SD-WAN vendors have come out of the woodwork. Many vendors have their roots in past WAN and even LAN solutions, ranging from router vendors, to firewall vendors, to WAN optimization vendors and even to wireless LAN providers. Each come to the table with strengths from their legacies as they invest in building new capabilities to become a comprehensive SD-WAN solution.
