WAN edge infrastructure enables network connectivity from distributed enterprise locations to access resources in both private and public data centers as well as cloud (as a service). It is typically procured by senior networking leaders within an infrastructure and operations (I&O) organization. This market has evolved from traditional branch routers (often called “customer edge routers” in a Multiprotocol Label Switching [MPLS] implementation), and is undergoing dramatic change, driven by the needs of digital business transformation and the demands of line-of-business managers. The market for branch office wide-area network functionality is shifting from dedicated routing, security and WAN optimization appliances to feature-rich SD-WAN and vCPE platforms. WAN edge infrastructure now incorporates a widening set of network functions, including secure routers, firewalls, SD-WAN, WAN path control and WAN optimization, along with traditional routing functionality.
