Network control protocol
The function of multi-link PPP is that it allows an enterprise to connect to multiple ISPs.
The most common WAN data-link protocols are: 1. HDLC 2. PPP 3. Frame Relay 4. ATM
HDLC - High level data link control used in conjunction with Networking protocols like PPP (point-to-point) protocol. According to RFC 1662, PPP uses HDLC like frame by providing address and control fields. For PPP these fields are constants 0xFF and 0x03.
Application: FTP, SMTP, HTTP Transport : TCP, UTP Network : IP, routing protocols Link : PPP ethernet Physical : bit
Data link layer protocols like PPP and HDLC define how data is encapsulated for transmission across a WAN link.
NCP (Network Control Protocol) is responsible for negotiating and configuring the network-layer parameters of a PPP (Point-to-Point Protocol) session. It establishes and manages the network control options needed for the successful communication between the two endpoints of the PPP link. NCP allows for the customization of network protocols and parameters to suit the specific requirements of the PPP connection.
You need to use a protocol that will translate serial protocol (your modem) to a packet based network. Protocols such as SLIP, PPP, PPTP are used for that purpose.
Internet (PPP) Accounts A PPP (Point-to-Point Protocol) account is an Internet account that uses the PPP communications protocol. PPP is the most popular type of Internet account because the most popular software--Internet Explorer, Netscape Navigator, Outlook Express, Eudora, and other programs--is designed to work with PPP accounts. Occasionally, you may run into a SLIP (Serial Line Internet Protocol) or CSLIP account (Compressed SLIP), which are old, less-reliable protocols than PPP, but which work the same way. This book refers to PPP, CSLIP, and SLIP accounts as dial-up Internet accounts. An Internet service provider (ISP) is an organization that provides Internet accounts, usually PPP accounts, but occasionally UNIX shell accounts. All ISPs provide dial-in accounts using regular phone lines, and many also provide ISDN and DSL connections
Point-to-Point Protocol (PPP) is used to set up a connection between two nodes. The advantage of Point-to-Point Protocol is that you can have several protocols running, one after the other, on the same wire.
the answer is that destiney is awesome. :ppp the answer is that destiney is awesome. :ppp
DATA Transmission is done through SLIP (Serial Line Internet Protocol) & PPP (Point to Point Protocol) Protocols to enable computers to interact with Internet over Telephone Line.
Differences between HDLC and PPP are(1) HDLC is cisco proprietary while PPP is an open standard.(2) HDLC does not provide authentication while PPP provides authentication like PAP and CHAP.(3) HDLC does not support compression while PPP support compression.(4) HDLC supports synchronous networks only while PPP supports both synchronous and asynchronous networks.
