WAN Protocol Family

A variety of different protocols are used on "wide-area networks" or WANs. At the physical layer, a line carrying a T1/E1/J1 signal or higher-speed T-carrier or E-carrier lines, or a fraction thereof, or a SONET/SDH optical link, or fraction thereof, could be used. Alternatively, a connection to a switched network, such as an X.25, FrameRelay, or ATM network might be used, with a line or optical connection such as the ones listed being used for that connection.

On top of that physical layer one might, for example, run PPP or Cisco HDLC, inside some HDLC-like framing.

10-gigabit Ethernet was intended to be used not only as a LAN or MAN protocol, but also as a WAN protocol.
