Is a WAN Backbone just another name for a WAN, or is there a difference? Many people think they’re the same, but that’s not entirely true. A WAN connects multiple locations, while a WAN Backbone is the core network that links these WANs together, providing high-speed data transmission and reliability. Without it, large networks would struggle with speed and connectivity.
