Protocole HDLC : High-Level Data Link Control. - Propriétaire CISCO - Supporte uniquement les liaisons synchrones - Absence d'authentification Cisco HDLC is an extension to the High-Level Data Link Control network protocol, and was created by Cisco Systems, Inc. HDLC is a bit-oriented synchronous data link layer protocol that was originally developed by the International Organization for Standardization. Often described as being a proprietary extension, the details of cHDLC have been widely distributed and the protocol has been implemented by many network equipment vendors. cHDLC extends HDLC with multi-protocol support Le HDLC est un protocole de niveau 2 du Modèle OSI, dérivé de SDLC. Son but est de définir un mécanisme pour délimiter des trames de différents types, en ajoutant un contrôle d'erreur. Il est défini par l'Organisation internationale de normalisation sous la spécification ISO 3309. Les interfaces série des routeurs Cisco utilisent une version propriétaire de HDLC par défaut In this lesson, we will talk about HDLC configuration on Cisco Routers. Cisco HDLC has a different proprietary field in the data field of the protocol. For our Cisco HDLC Configuration example, we will use the below basic topology: Let's start to configure Cisco HDLC for this topology

HDLC est un protocole L2 standardisé que les interfaces série des routeurs Cisco implémentent par défaut. HDLC Cisco n'est pas standard dans le sens où il ajoute un champ supplémentaire Protocol de 16 bits qui annonce la charge supérieure. Ce champ supplémentaire lui permet de transporter des protocoles L3 (de couche 3, Internet ou Réseau) HDLC (contrôle de liaison de données de haut niveau) est un protocole de communication utilisé au niveau de la couche liaison de données des réseaux informatiques, développé par l'ISO (organisation internationale de normalisation). PPP est un protocole de couche de liaison de données basé sur HDLC et très similaire à HDLC Le HDLC est le type d'encapsulation par défaut sur une interface de routeur de POS. Le HDLC est une norme internationale, mais les réalisations de constructeur varient un ou plusieurs champs ou l'en-tête ou la remorque dans la taille et formatent Yes - the Cisco version of HDLC is indeed cisco proprietary and won't run with any other vendors. There are other vendors out there that actually supports HDLC, but you won't be able to run them towards a Cisco-device. To understand why, you would need to look at the framing-itself and see how it's different

HDLC is the default encapsulation protocol type on point-to-point connections, dedicated links, and circuit-switched links when the link uses two Cisco devices. It is a synchronous Data Link layer bit-oriented protocol originally developed from the Synchronous Data Link Protocol (SDLC) and became standardized by ISO as ISO 13239. It provides both connection-oriented an It's a point-to-point protocol and it's the default for serial interfaces on Cisco routers. HDLC is a standard but running HDLC between routers from different vendors is not going to work. Keep this in mind. Every vendor has a proprietary field in their HDLC implementation which is what makes it incompatible between vendors Cisco's version of HDLC is actually proprietary because they added a protocol type field. Thus, Cisco HDLC can only work with other Cisco devices. HDLC is actually the default protocol on all Cisco serial interfaces. If you do a show running-config on a Cisco router, your serial interfaces (by default) won't have any encapsulation | HDLC , qui est propriétaire Cisco. C'est un protocole qui supporte uniquement les liaisons synchrones et qui ne dispose pas d'option d'authentification. | Et on à PPP, qui lui, est normalisé, supporte les liaisons synchrones et asynchrones. Et possède une authentification avec les protocoles PAP et CHAP Construit sur la base du Synchronous Data Link Control (SDLC) créé par IBM, HDLC a maintenant été modifié par Cisco et est utilisé comme protocole par défaut sur la plupart des interfaces série Cisco. Le protocole HDLC est une forme de protocole orienté bit capable de supporter différentes formes de connexions telles que.

The original HDLC did not have a protocol ID field so an HDLC circuit could transport only a single protocol. Cisco improved this limitation at the expense of making its own cHDLC incompatible with the standard. Actually, the HDLC run by default on Cisco serial and ISDN interfaces is the cHDLC, not the plain basic HDLC Point-to-Point Protocol (PPP, protocole point à point) est un protocole de transport pour l'Internet, décrit par le standard RFC 1661, fortement basé sur HDLC, qui permet d'établir une connexion entre deux hôtes sur une liaison point à point. Il fait partie de la couche liaison de données (couche 2) du modèle OSI HDLC is a bit-oriented protocol. There are two types of HDLC protocol, that is, ISO HDLC and Cisco HDLC. It supports both synchronous and asynchronous links. HDLC does not support authentication i.e it fails to provide authentication between two nodes

Cisco routers use a proprietary extension to the industry-standard HDLC frame. It's called cHDLC and it utilizes a network protocol field in the header to support several different higher layer protocols that HDLC will encapsulate. If you're peering with a non-Cisco router and using HDLC encapsulation, you may have a problem HDLC - on point-to-point networks, this is the default WAN protocol that is used by CISCO devices. It also defines some of the communication parameters used in PPP. PPP - is a protocols that connects many routers to the WAN, PPP is works at layer 2 and is independent of the Layer 3 protocol in use. This means that it can use IP, IPX and appletalk Standard HDLC Protocol contains six fields. Whereas on the other hand, Cisco HDLC (cHDLC) contains one extra protocol field. The standard protocol uses to support only one protocol whereas cHDLC protocol use to support multi-protocol environments. Supporting multiple protocols is possible due to protocol field in header, that helps in identifying different protocols. cHDLC was basically created by Cisco systems HDLC is a layer two protocol that provides encapsulation method for serial link. Serial link and Ethernet link both use different encapsulation methods for data transmission. Serial link cannot carry the frame formatted with Ethernet encapsulation and vice versa Ethernet link cannot carry the frame formatted through the Serial encapsulation The frame structure of HDLC contains the address, control, data, checksum and flag fields. The default encapsulation protocol in the Cisco devices is the HDLC. The Cisco proprietary HDLC only works when the devices in both of the ends of the link are of cisco. Standard HDLC can have different devices in the ends

HDLC is a synchronous Data Link layer bit-oriented protocol developed by the International Organization for Standardization (ISO). The current standard for HDLC is ISO 13239. HDLC was developed from the Synchronous Data Link Control (SDLC) standard proposed in the 1970s. HDLC provides both connection-oriented and connectionless service Cisco HDLC Cisco HDLC is a datalink protocol for point to point WAN connections. It is the default encapsulation for serial lines. There is no windowing no flow control, only point to point. Some extensions allow multiprotocol support before ppp was specified * will not interoperate with other HDLC implementations * use PPP when interoperability is required, for example if two Nortel and Cisco. Le HDLC (sigle anglais pour High-Level Data Link Control) est un protocole de niveau 2 (couche de liaison) du Modèle OSI, dérivé de SDLC (Synchronous Data Link Control).Son but est de définir un mécanisme pour délimiter des trames de différents types, en ajoutant un contrôle d'erreur. Il est défini par l'Organisation internationale de normalisation sous la spécification ISO 3309. HDLC stads for High-Level Data Link Control. This library adapts the HDLC protocol for standard serial, allowing easy communication with CRC error detection among microcontrollers connected via a serial bus.
