Enterprise Networking and Communications refers to the products and services that enable secure, scalable, and high-performance connectivity and communication across distributed enterprise environments. This category includes markets that focus on core and edge networking, unified communications, private and public mobile networks, and managed network services—supporting digital transformation, and operational efficiency.
Gartner defines software-defined WAN (SD-WAN) as products used to connect branch locations to other enterprise and cloud locations. SD-WAN products provide dynamic path selection based on business or application policy, routing, centralized orchestration of policy and management of appliances, virtual private network (VPN) and zero-touch configuration. SD-WAN products are WAN transport/carrier-agnostic and create secure paths across physical WAN connections.
Gartner defines WAN optimization tools as products that improve the performance of applications running across the WAN as well as reduce WAN service expenses. WAN optimization solutions continue to evolve, and now support four high-level needs: improving the response times for users of business-critical applications over WAN links or mobile connections; assisting in maximizing ROI for WAN bandwidth; optimizing data-center-to-data-center (DC-to-DC) traffic for faster storage replication and synchronization; and assisting in directing traffic across multiple WANS, such as a hybrid WAN or public cloud connectivity.
