    36 - Smooth Sailing Network Overhaul

    In today's episode, Cisco CX engineers and architects reveal how cruise ship networks are built and upgraded: everything from door locks and cameras to navigation and guest entertainment runs over the same segmented, secured infrastructure, and internet connectivity depends on intermittent satellite links so content must be stored locally. We follow a high‑stakes dry dock upgrade on a large cruise ship — with tight timelines, complex staging, and on‑the‑fly design changes to handle issues like NAT, multicast/PTP, MTU and firewall integration — and learn how planning, testing and rapid problem‑solving kept the ship sailing.
