The simplest forwarding model - [[unicast|unicasting]] - involves a packet being

Less common than broadcasting, but perhaps of greater
utility and theoretical
where a packet is selectively duplicated and copies
delivered to each of a set of recipients.
Line 31 ⟶ 35:
of two processes: [[routing]], which uses information
encoded in a device's address to infer its ___location
on the network, or [[bridging (networking)|bridging]], which makes no
assumptions about where addresses are located and
depends heavily on [[broadcasting (networks)|broadcasting]] to located unknown
