The point-to-point protocol is an industry standard suite of protocols which uses the point-to-point link to transport multiprotocol datagram. The point-to-point protocol is a WAN protocol used at layer 2 to encapsulate the frames for the data transmission over the physical layer.
Following are the features that point-to-point protocol provides :
* Link quality management : It is a technique to monitor the quality of a link. If it finds any error in a link, then the link is shut down.
* The point-to-point protocol also provides authentication.
* It provides some essential features such as authentication, error detection, link quality monitoring, load balancing, compression, etc.
Components of a point-to-point protocol are:
* Encapsulation : Point-to-point protocol encapsulates the network packets in its frames using HDLC protocol. This makes the PPP layer three layer independent.
* Link Control Protocol : Link Control Protocol is used for establishing, configuring and testing the data link over internet connections.
* Network Control Protocol : Point-to-point protocol is used in a data link layer in the OSI reference model. The data comes from the upper layer, i.e., transport layer or network layer is fully compatible with PPP due to the presence of a Network control protocol.
