hdlc protocol ppt

yFrame Relay:thispprotocol uses an HDLC pprocedure for its link o pperations. It owes its name mainly to its purpose, which is to highlight HDLC‐type frames through the network. HDLCs can provide both connection-oriented and connectionless services. HDLC, PPP & SLIP. 이번 장은 hdlc 프로토콜에 대해서 공부를 하는데 이렇게 특정한 프로토콜에 대해 공부를 하게 되면 다른 프로토콜들을 이해하는데도 크게 도움이 된다. Medan Kendal CONTOH OPERATION 2 Protokol HDLC (High Level Datalink Control) pada koneksi WAN • PROTOCOL DATA LINK CONTROL • Lapisan data-link (data link layer) adalah lapisan kedua dari bawah dalam model OSI, yang dapat melakukan konversi frame-frame jaringan yang berisi data yang dikirimkan menjadi bit-bit … ; The communication channel that connects the adjacent nodes is known as links, and in order to move the datagram from source to the destination, the datagram must be moved across an individual link. Though HDLC is technically an ISO standard protocol, Cisco’s implementation of HDLC is proprietary, and will not work with other routers. View High-level Data Link Control(HDLC).ppt from ECE 107 at Jaypee Institute of Information Technology. Frame Relay was derived from many of the LAPD and V.120operations. In next part I will explain PPP protocol and encapsulation method in detail with example. That’s all for this part. HDLC (High Level Data Link Control), L2TP (Layer 2 Tunneling Protocol), and PPPoE (Point-to-Point Protocol over Ethernet) provide such protocols. It is also used for synchronous PPP connections. 三、hdlc 1. • On transmit side, HDLC receives data from application and delivers it to the receiver on the other side of link. PowerPoint Presentation : Figure 11-15 WCB/McGraw-Hill The McGraw-Hill Companies, Inc., 1998 HDLC Modes. HDLC is a point-to-point protocol used on leased lines and ISDN dial-up connections. The High-Level Data-Link Control (HDLC) protocol is a popular ISO-standard, bit-oriented Data Link layer protocol. It specifies an encapsulation method for data on synchronous serial data links using frame characters and checksums. View Notes - PPP-HDLC-PAP-CHAP.ppt from CS 4404 at University of the People. The High-Level Data-Link Control (HDLC) protocol is a popular ISOstandard, bit-oriented Data Link layer protocol. • It is bit oriented protocol. By : Naveen Kumar. It is recommended that values in the "02xx" … HDLC is a group of data link (Layer 2) protocols used to transmit synchronous data packets between point-to-point nodes. PPP Protocol Overview. with … PowerPoint Presentation : Figure 11-16 WCB/McGraw-Hill The McGraw-Hill Companies, Inc., 1998 HDLC Frame Types. Link Access Protocol Balanced (LAPB) is one of the three layers making up X.25 and was a development by ITU-T, of LAP which itself came from HDLC. HDLC is an ISO standard developed from the … HDLC is the default encapsulation method in Cisco routers. The HDLC protocol embeds information in a data frame that allows devices to control data flow and correct errors. High-Level Data Link Control (HDLC) was created out of SDLC by the ISO in 1979 (see later). HDLC (High-Level Data Link Control) HDLC (High-Level Data Link Control) is a Layer 2 WAN Encapsulation Protocol that we use it on Syncronous data links. ECE, NITTTR CONTENTS Data link protocols HDLC Overview HDLC Basics HDLC Frame structure HDLC operation by some examples PPP introduction and Features PPP Frame structure SLIP Basics Applications of PPP & HDLC Summary References. In the OSI model, the data link layer is a 4 th layer from the top and 2 nd layer from the bottom. One of them is the standard one and the other is the … it is a data link layer protocol. 什么是hdlc hdlc是高级数据链路控制协议，是一种数据链路层的协议。hdlc是一个iso标准的面向位的数据链路协议,其在同步串行数据链路上封装数据，最常用于点对点链接。hdlc主要有以下几个特性： ① 协议不依赖于任何一种字符编码集。 “Implementing DLMS Protocol in Meters” A White Paper Kalki Communication Technologies Limited #147, 5th Main, HSR Layout, Sector 7 Bangalore 560102, India E-mail: info@kalkitech.com Phone: 91-80-4052 7900 Web: www.kalkitech.com Hdlc and Ppp - Free download as Powerpoint Presentation (.ppt), PDF File (.pdf), Text File (.txt) or view presentation slides online. No authentication can be used with HDLC. HDLC (not part of PPP protocol suite but provided by ISO 3309 HDLC). M.E. High-Level Data Link Control (HDLC) is a bit-oriented code-transparent synchronous data link layer protocol developed by the International Organization for Standardization (ISO). The High-Level Data-Link Control (HDLC) protocol is a popular ISO-standard, bit-oriented, Data Link layer protocol. 2 HDLC Support for MS-DOS 1 FELINE/ParaScope Pod (Parallel interface). The HDLC protocol is a general purpose protocol which operates at the data link layer of the OSI reference model.The protocol uses the services of a physical layer, and provides either a best effort or reliable communications path between the transmitter and receiver (i.e. PPP协议和HDLC协议是目前应用最常用的广域网中的链路层协议。 2 PPP协议 点对点协议PPP（Point-to-Point Protocol）是目前使用最广泛的数据链路层协议，用于使用拨号电话接入因特网时一般都使用PPP协议，是面向字节的数据链路层协议。 PPP协议只支持 … All Protocols MUST be assigned such that the least significant bit of the most significant octet equals "0", and the least significant bit of the least significant octet equals "1". High-Level Data Link Control: A high-level data link control (HDLC) is a protocol that is a bit-oriented synchronous data link layer. It is the simplest WAN Protocol that can connect your remote offices over leased lines. The Protocol field is consistent with the ISO 3309 (HDLC) extension mechanism for Address fields. yLAP‐X:isahalf‐duplexcontrol protocol used in teletextechnology. A proprietary HDLC protocol will not work with other vendor’s HDLC. The standard for HDLC is ISO/IEC 13239:2002. It hdlc介绍hdlc是点到点串行线路上（同点电路）的帧封装格式，其帧封装格式和以太网帧格式有很大的差别，hdlc帧没有源mac地址和目的mac地址。思科对hdlc进行了专有化，思科的hdlc和标准的hdlc不兼容。如果链路两端都是思科设备，可以使用hdlc封装，如果是思科和非思科设备进行连接 应使用ppp协议。 Understanding Physical Encapsulation on an Interface, Understanding Frame Relay Encapsulation on an Interface, Understanding Point-to-Point Protocol, Understanding High-Level Data Link Control 3309 HDLC ) is a point-to-point protocol used on leased lines and dial-up...
