A communication facility or physical medium that can sustain data communications between multiple network nodes, in the protocol layer immediately below IP. (RFC 3753)
A communication channel connecting subnetwork relays (especially one between two packet switches) that is implemented at OSIRM Layer 2. (See: link encryption.)
Tutorial: The relay computers assume that links are logically passive. If a computer at one end of a link sends a sequence of bits, the sequence simply arrives at the other end after a finite time, although some bits may have been changed either accidentally (errors) or by active wiretapping.
