Applications At Data Link Layer
A data link layer technology, such as media access control (MAC) protocols on local area networks, has an address that has no significance beyond a single medium.
Besides Ethernet bridging based on MAC layer addresses, other data-link-layer technologies using forwarding tables include frame relay and Asynchronous Transfer Mode (ATM) switches, and multiprotocol label switching (MPLS). ATM has both link-local addresses and addresses that have end-to-end significance in the ATM domain.

Famous quotes containing the words data, link and/or layer:
“This city is neither a jungle nor the moon.... In long shot: a cosmic smudge, a conglomerate of bleeding energies. Close up, it is a fairly legible printed circuit, a transistorized labyrinth of beastly tracks, a data bank for asthmatic voice-prints.”
—Susan Sontag (b. 1933)
“Because this age and the next age
Engender in the ditch,
No man can know a happy man
From any passing wretch,
If Folly link with Elegance
No man knows which is which....”
—William Butler Yeats (1865–1939)
“A revolution is not the overturning of a cart, a reshuffling in the cards of state. It is a process, a swelling, a new growth in the race. If it is real, not simply a trauma, it is another ring in the tree of history, layer upon layer of invisible tissue composing the evidence of a circle.”
—Kate Millett (b. 1934)
