PPP is a data link layer industry standard WAN protocol for transferring multi-protocol data trafﬁc

over point-to-point connections. With this protocol, options such as security, data compression,

and network protocols can be negotiated over the connection.

Frame Relay is a packet-switching data communications protocol that statistically multiplexes

many data conversations over a single transmission link. Data compression allows Frame Relay to

negotiate compression over Frame Relay permanent virtual circuits (PVCs).

ISDN BRI is a switched Data Link layer control protocol which uses digital signaling to place a

call into an ISDN network. Once the call is made, PPP is then used to transfer data.
