hdlc protocol software

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

, 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 s

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 fi

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 descr

HDLC is the default protocol used by CISCO routers. A new router uses HDLC Encapsulation by default when no encapsulation protocol is specified.1. Related commandsPort Settings　 Note: 1.

protocol based, meaning that LoadRunner test objects need to use a communication protocol for software that does not use the communication protocol for local processing only, such as Microsoft Word,loadrunner is not applicable. Speaking of communication protocols, let's familiarize ourselves with the

events correspond to corresponding actions. For example, some actions indicate the transmission of different types of LCP packets or the start and stop of Restart timer.The status jump table is in the PPP link operation. After a specific event, each status changes to a new State and there may be corresponding events. These relationships are complex and can be expressed in the status jump table [1. 3 software implementation3.1

I want to share with you an article on the HTTP protocol. It is very helpful for new users who are waiting for network analysis.Original post address: http://www.csna.cn/viewthread.php? Tid = 371 I. PurposeI have been learning network analysis for some time. Now I am getting started. I think I didn't know where to start when I first came into contact. To learn about network analysis, you must start with the protoc
