+ <p>PPP uses a layered architecture. A
+ layered architecture is a logical model, design, or blueprint that
+ aids in communication between interconnecting layers. The Open System
+ Interconnection (OSI) model is the layered architecture used in
+ networking. PPP provides a method for encapsulating multi-protocol
+ datagrams over a point-to-point link, and uses the data link layer for
+ testing the connection. Therefore PPP is made up of two sub-protocols:
+ <img border="0" src="../../images/1.gif" align="middle" width="12" height="12"><ul>
+ <li><b>Link Control Protocol</b> – Used for establishing the point-to-point
+ link. <img border="0" src="../../images/2.gif" align="middle" width="12" height="12"></li>
+ <li><b>Network Control Protocol</b> – Used for configuring the various
+ network layer protocols.
+ <img border="0" src="../../images/3.gif" align="middle" width="12" height="12"></li>
+ </ul>
+ <p>PPP can be configured on the following types of physical interfaces:<ul>
+ <li>Asynchronous serial</li>
+ <li>Synchronous serial</li>
+ <li>High-Speed Serial Interface (HSSI)</li>
+ <li>Integrated Services Digital Network (ISDN) </li>
+ </ul>
+ <p>PPP uses Link Control Protocol (LCP) to negotiate and setup
+ control options on the WAN data link. PPP uses the Network Control
+ Protocol (NCP) component to encapsulate and negotiate options for
+ multiple network layer protocols. The LCP sits on top of the physical
+ layer and is used to establish, configure, and test the data-link
+ connection.
+ <p>PPP also uses LCP to automatically agree upon encapsulation format
+ options such as:<ul>
+ <li><b>Authentication</b> – Authentication options require that
+ the calling side of the link enter information to help ensure
+ the caller has the network administrator's permission to make
+ the call. Peer routers exchange authentication messages. Two
+ authentication choices are Password Authentication Protocol
+ (PAP) and Challenge Handshake Authentication Protocol (CHAP). </li>
+ <li><b>Compression</b> – Compression options increase the effective throughput
+ on PPP connections by reducing the amount of data in the frame that
+ must travel across the link. The protocol decompresses the frame at
+ its destination. Two compression protocols available in Cisco routers
+ are Stacker and Predictor. </li>
+ <li><b>Error detection </b>– Error detection mechanisms with PPP enable a
+ process to identify fault conditions. The Quality and Magic Number
+ options help ensure a reliable, loop-free data link. </li>
+ <li><b>Multilink</b> – Cisco IOS Release 11.1 and later supports multilink
+ PPP. This alternative provides load balancing over the router
+ interfaces that PPP uses. </li>
+ <li><b>PPP Callback</b> – To further enhance security, Cisco IOS Release 11.1
+ offers callback over PPP. With this LCP option, a Cisco router can act
+ as a callback client or as a callback server. The client makes the
+ initial call, requests that it be called back, and terminates its
+ initial call. The callback router answers the initial call and makes
+ the return call to the client based on its configuration statements.
+ </li>
+ </ul>
+ <p>LCP will also do the following:<ul>
+ <li>Handle varying limits on packet size </li>
+ <li>Detect common misconfiguration errors </li>
+ <li>Terminate the link</li>
+ <li>Determine when a link is functioning properly or when it is failing</li>
+ </ul>
+ <p>PPP permits multiple network layer protocols to operate on the same
+ communications link. For every network layer protocol used, a separate
+ Network Control Protocol (NCP) is provided. For example, Internet
+ Protocol (IP) uses the IP Control Protocol (IPCP), and Internetwork
+ Packet Exchange (IPX) uses the Novell IPX Control Protocol (IPXCP). NCPs
+ include functional fields containing standardized codes to indicate
+ the network layer protocol type that PPP encapsulates.
+ <p>The fields of a PPP frame are as follows:<ul>
+ <li><b>Flag</b> – Indicates the beginning or end of a frame and consists of the
+ binary sequence 01111110. </li>
+ <li><b>Address</b> – Consists of the standard broadcast address, which is the
+ binary sequence 11111111. PPP does not assign individual station
+ addresses. </li>
+ <li><b>Control</b> – 1 byte that consists of the binary sequence 00000011,
+ which calls for transmission of user data in an unsequenced frame. A
+ connection-less link service similar to that of Logical Link Control
+ (LLC) Type 1 is provided. </li>
+ <li><b>Protocol</b> – 2 bytes that identify the protocol encapsulated in the
+ data field of the frame.
+ <img border="0" src="../../images/4.gif" align="absmiddle" width="12" height="12"></li>
+ <li><b>Data</b> – 0 or more bytes that contain the datagram for the protocol
+ specified in the protocol field. The end of the data field is found by
+ locating the closing flag sequence and allowing 2 bytes for the frame
+ check sequence (FCS) field. The default maximum length of the data
+ field is 1,500 bytes. </li>
+ <li><b>FCS</b> – Normally 16 bits or 2 bytes that refers to the extra
+ characters added to a frame for error control purposes.</li>
+ </ul>
