WAN edge infrastructure is changing rapidly as I&O leaders responsible for networking face dynamic business requirements, including new application architectures and on-premises and cloud-based deployment models. I&O leaders can use this research to identify vendors that best fit their requirements. By year-end 2023, more than 90% of WAN edge infrastructure refresh initiatives will be based on virtualized customer premises equipment (vCPE) platforms or software-defined WAN (SD-WAN) software/appliances versus traditional routers (up from less than 40% today).
"SD-WAN largely exists today to support two key enterprise transformations: multicloud and the software-defined branch (SD-Branch).
Multicloud has changed the center of gravity for enterprise applications, and with that, has changed traffic patterns too. No longer does traffic need to flow to enterprise data center sites or central internet peering points and breakouts. That’s because most traffic from users and devices in the enterprise campus and branch today goes to cloud-based applications scattered across a host of clouds.
It’s neither economical nor efficient to haul traffic over WAN-dedicated links to a central enterprise site. So to optimize the cost and performance of multicloud-bound traffic, modern WAN edge routers, often called customer premises equipment (CPE), are now equipped with hybrid WAN links and routing. Hybrid WAN interfaces may include WAN provider-dedicated links such as MPLS, as well as direct internet links over xDSL, broadband and 4G/LTE wireless."

Wireless technologies are migrating from complex hierarchical voice-oriented architectures to flatter, low latency, all-IP based designs – reducing cost and complexity for service providers while efficiently supporting real time IP services. Coupled with this trend is the migration to higher performance OFDMA air links with MIMO and AAS, providing much greater bandwidth with improved interference characteristics.

Rising demand for multimedia applications and mobile usage requires new paradigm to shift voice-oriented cellular architecture into data-oriented networks in order to serve bandwidth hungry packet based applications which include but not limited to multimedia gaming, mobiTV, streaming media, P2P, etc. Data oriented network requires 20-fold fatter air link and backhaul as compared to typical voice communication.
