Packet Post

Six deliveries. A broken link. One very mixed-up inbox.

Ready for deliveryDeliveries solved: 0 / 6
Message pieces traveling between a sender, relay stations, a library and a museum.

A packet carries data and information about where it belongs. Plan a route, cross one link at a time, then put the numbered pieces back together.

This is a closed teaching model, not real network equipment. Links are two-way and only drawn links exist. Labels and requests are pretend; nothing is sent to another device.

Learning Focus Plan, route, rebuild and explain. Optional practice, not a grade.

Fun fact: A shorter route by hop count can take longer than a route with more hops. The link times in delivery three let you check an example.

Our numbered word pieces simplify real networking. Different protocols handle ordering and loss differently; these labels are not a literal packet format.
