What this diagram shows
- Card payments run on a separate PCI network
- Kitchen displays keep working if the internet link fails
- Every store connects to HQ over SD-WAN
Prompt used
QSR store network: an SD-WAN edge device links the store to headquarters and the cloud POS. VLANs separate POS terminals and self-order kiosks, a PCI VLAN for card terminals, kitchen display screens and printers, the drive-thru headset and order-confirmation system, guest Wi-Fi, and CCTV. A local store server caches menus and orders for offline operation.
