The outgoing interface will encapsulate the packet in the appropriate data link protocol.
2.
This is because the Internet places no constraints on what physical medium or data link protocol is used.
3.
For the Internet, the physical medium and data link protocol can vary several times as packets traverse the globe.
4.
RSCS used synchronous data link protocols, not SNA / SDLC, to support file to file transfer among virtual machine users.
5.
The data link protocol is based on the ISO standards used for dial-up HDLC access to X . 25 networks.
6.
However, IP can run over a reliable data link protocol such as the High-Level Data Link Control ( HDLC ).
7.
The Consultative Committee for Space Data Systems'Space Data Link Protocol implements an out-of-band mechanism via the " command " flag.
8.
Examples of packet mode data link protocols that can be / are transferred using synchronous serial communication are the HDLC, Ethernet, PPP and USB protocols.
9.
The DECT data link layer uses Link Access Protocol Control ( LAPC ), a specially designed variant of the ISDN data link protocol called LAPD . They are based on HDLC.
10.
Examples of data link protocols are Ethernet for local area networks ( multi-node ), the Point-to-Point Protocol ( PPP ), HDLC and ADCCP for point-to-point ( dual-node ) connections.
