What are LAN, WAN, SDN & SD-WAN?

A Wide Area Network (WAN) is a network that interconnects multiple Local Area Networks (LANs), which can use either WiFi or Ethernet. If you have multiple sites connected to each other over the internet or remote users accessing your company’s resources, then you have a WAN.

Software-Defined Networking (SDN) is a modern approach to controlling network hardware using software running in the cloud. SDN not only reduces hardware costs but also enables integration with other systems, providing powerful features such as faster setup, improved network failure handling, and enhanced cybersecurity.

A Software-Defined Wide Area Network (SD-WAN) applies the SDN approach to managing WAN hardware, commonly referred to as a WAN router or simply a router. Through cloud-based management, SD-WAN securely interconnects routers over the internet, supports multiple ISP connections for redundancy, and allows remote users to connect securely.
