This phase is optional when there is no such request made. Any peer may request validation after link configuration. However, both peers should be able to recognize the padding bytes from the true data.Ĥ.3 Block diagram To establish communication between two peers, LCP packets must first be sent both ways to configure the link. The information field may be padded with as many bytes as needed to reach the MRU. Negotiations are possible between peers as to the MRU values. The default field length is also 1500 bytes. This limit is termed as the Maximum Receive Unit (MRU) at the receiving end and Maximum Transmit Unit (MTU) at the transmitting end.
It has a maximum length (including padding and excluding the protocol field) of 1500 bytes.

Some examples of protocol field values are: 0xC021 for Link control protocol 0xC023 for Password Authentication Protocol 0x8021 for Internet Protocol Control ProtocolĤ.2.2 Information field This field is zero or more bytes long. Frames that violate these rules are treated as unrecognized protocols. The least significant bit of the lower byte is always set to "1" and that of the most significant bit is always set to "0". Protocol 8 - 16 bitsįigure 4.1: Encapsulation of PPP packets 4.2.1 Protocol field This field is one or two bytes and it identifies the data being sent in the information field. Data is transmitted from the left to right. Data is sent in frames whose general structure is shown in Figure 4.1. Network Control Protocol (NCP)Ĥ.2 Encapsulation Encapsulation is provided by PPP so that different protocols at the network layer can be supported simultaneously. PPP can be fragmented into three parts: 1. The point-to-point links that utilize this protocol should be able to support full-duplex communication. Information is exchanged in the form of structured data packets. PPP is a protocol that can be used to establish communication between any two communicating devices that need to exchange information. Ĥ.1 Introduction to PPP Much help was acquired from Internet Request-For-Comments (RFC) documents on the details of the point-to-point protocol.
