High-Level Data Link Control (HDLC) is a bit-oriented data link layer protocol for data transmission over the synchronization network. It is an International Organization for Standardization (ISO) developed based on the ibm sdlc (synchronous Data Link Control) protocol.The Link Control Protocol focuses on the logical transmission of segments into physical blocks or packets. A block or packet is guided by the Starting Sign and ended by the ending sign,

Package for synchronous serial link (serail point-to-point link)3.1-hdlc/ppp High-level Data link Control HDLC (high-level Data Link controls): is a bit-oriented synchronous data Link layer protocol developed by ISO, developed by the SDLC protocol. HDLC Specifies the encapsulation on a synchronous serial line by using frame characters and checksums, and

HDLC frame format In HDLc, data and control packets are transmitted in the standard frame format. Frames in HDLC are similar to BSC character blocks, but the datagram and control packets in the BSC protocol are transmitted independently. commands in HDLC should be transmitted by frame in a unified format. The

, PPP can carry other protocols, including DECnet and Novell's Internet Packet Exchange (IPX).Iii. HDLChdlc---bit-oriented synchronization protocol: High-level Data link control (Advanced Information link controls procedures). HDLC is a typical representative of the bit-oriented data Link Control protocol, which does not depend on any kind of character encoding set, the data message can be transparently transmitted, the "0-bit insertion method" for tr

Routers are often used to build wide-area networks, and the footprints of WAN links are very different from those on Ethernet. Common WAN packages are HDLC, PPP, Frame-relay, etc., and this chapter describes HDLC and PPP. PPP, in contrast, has more functions than HDLC.1.1.1 HDLC IntroductionHDLC is a frame-wrapping for

PPP Protocol (Point-to-place protocol) belongs to the network interface layer, which is mainly used for dial-up internet access. PPP has the ability to dynamically assign IP addresses, allows IP addresses to be negotiated at the time of connection, has error detection and correction capability, and supports data compression; in order to establish point-to-point link traffic, each end of the PPP link must first send the LCP packet to set up and test the data link. After the link is established an

I. Applicable conditions: 1. DDN is the main line, and PSTN is the standby line. 2. The HDLC protocol is used on DDN and the PPP protocol is used on PSTN. 3. dynamic routing can be performed on the main line or the standby line. In this example, dynamic routing is performed on the main line. II, Network Topology: Iii. Solution description: HDLC support is one of the most impor
