Core Networking Concepts Module Guide

Follow Packet Pete as one leak alarm must preserve a local warning and a truthful remote update.

  1. Packet Pete sees one sensor event branch toward a local warning and a remote screen.

    One leak alarm has two needed results.

  2. Packet Pete observes as the local warning works while the remote path is broken.

    Keep the nearby warning active during a link break.

  3. Pete follows the remote message through a gateway to the screen.

    Trace each hop to the remote screen.

  4. Pete compares source time with the screen time and marks the stale value.

    Reject an old screen value as current.

One leak alarm must preserve a local warning and a truthful remote update.
