Gartner defines global WAN services as points-of-presence (POP)-based services supporting multiregional corporate networks. Service providers own and operate their own global core networks and sell directly to the client. Services include transport-centric/unmanaged, managed, and co-managed network services, or network as a service via a monthly fixed or usage-based fee model. These services are measurable and consumable through customer-facing web portals and programmable APIs. Global WAN services consist of backbone network transport and last-mile access connections, providing connectivity to individual enterprise sites such as large offices or remote branches. WAN service providers are also offering more transformational capabilities, such as cloud fabrics and enhanced visibility enabled by the underlay service network, and adding more network-based security functions to their offerings. Ancillary services such as cloud interconnects, managed SD-WAN and secure access service edge (SASE) are now commonly offered. Gartner also sees providers increasingly investing in AI and automation to support more service processes across the WAN service life cycle, from network design to service assurance.
The managed network services (MNS) market focuses on externally provided, network operations center (NOC) functionality, as well as relevant network and security life cycle services that deliver current and emerging requirements to end users. Gartner defines the MNS market as globally capable providers of remote service management functions for the network and security operations of enterprise networks, including: Managed LAN services (MNS for LAN) Managed WAN services (MNS for WAN) Managed security (MNS for security) functions
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.
