Question

What protocol does ppp use to end fight the network layer protocol?

Answer 1

It is 5.8 PPP: the point to point protocol

Most of our discussion of data link protocols thus far has focused on protocols for broadcast channels. In this section we cover a data link protocol for point-to-point links - PPP, the Point-to-Point protocol. Because PPP is typically the protocol of choice for a dialup link from residential hosts, it is undoubtedly one of the most widely-deployed data link protocols today. The other important data link protocol in use today is the HDLC (High Level Data Link Control) protocol; see [Spragins 1991] for a discussion of HDLC. Our discussion here of the simpler PPP protocol will allow us to explore many of the most important features of point-to-point data link protocol.
