"a 20-ton packet as the format, and container port protocol as the protocol" ? Please explain. 20-ton as a format ? is that 20 feet ? also known as a Twenty feet Equivalent Unit (a TEU). "container port protocol" - which protocol is that ? Martin

  20-ton packet is my informal way of refering to a TEU. The container shape and load limits are the physical analogy of the IP packet structure and length limits, hence a network "format". As for the "container port protocol", think of what a multiprotocol IP router does: it takes an IP packet off an ATM network and puts it on an Ethernet network. A container port does the same thing between a ship "network" and a "truck" network. In the case of the container port, the protocol is the set of formal and informal rules about which order to put which TEUs where.

  Informal is ok, but TEU means Twenty FEET Equivalent Unit, not Twenty TON Equivalent Unit. Certain weight limitations applies to containers, but they are not related to the term TEU.
