gateway
The term "router" is now used in place of the original definition
of "gateway". Currently, a gateway is a communications
device/program which passes data between networks having similar
functions but dissimilar implementations. This should not be
confused with a protocol converter. By this definition, a router
is a layer 3 (network layer) gateway, and a mail gateway is a
layer 7 (application layer) gateway. See also: mail gateway,
router, protocol converter.
router
A device which forwards traffic between networks. The forwarding
decision is based on network layer information and routing tables,
often constructed by routing protocols. See also: bridge,
gateway, Exterior Gateway Protocol, Interior Gateway Protocol.
per layer si intendono il livelli dello stack iso/osi
