Transport Protocols Module Guide

Follow Packet Pete as a safe link over lossy radio needs flight, wait, retry, and state evidence.

  1. Packet Pete follows the first message flight from device to peer across a weak radio path.

    A small device starts a safe link over a radio that loses messages.

  2. Pete records the ordered exchange as one message is lost and sent again.

    Save each flight, check, wait, retry, and result.

  3. Pete watches those three costs rise during repeated sends.

    More retries use more time, power, and radio space.

  4. Pete keeps the short return path separate from a full new setup and checks its stored state.

    A short return uses old state, so test that state too.

A safe link over lossy radio needs flight, wait, retry, and state evidence.
