IEEE 802.2 — Wikipédi

IEEE 802.2 est un groupe de travail (en « hibernation ») du comité IEEE 802 qui a développé et spécifié le protocole Logical Link Control.C'est aussi une norme qui a été publiée le 7 mai 1998 et reprise par l'ISO sous la dénomination ISO/CEI 8802-2:1998. Ce protocole qui propose plusieurs types d'opérations liés à des services de qualités différentes correspond à la sous. Structure d'une trame 802.2. Les données du niveau LLC, quel que soit le type, sont structurées sous la forme d'un LPDU ( LLC Protocol Data Unit ). Une trame LLC est encapsulée dans la trame de niveau inférieur ( MAC ). Le LPDU correspond donc au champ de données de la trame MAC LLC - IEEE 802.2 Logical Link Control Logical Link Control - IEEE 802.2 The IEEE 802.2 standards for Logical Link Control define a programming interface between that part of the communications software that controls the network interface card (the Media Access Control and Physical Medium Dependent components) and the overlying protocol stack (IP, NetBIOS, NetWare, etc.) IEEE 802.2 est le nom d' origine de la norme ISO / IEC 8802-2 norme qui définit un contrôle de liaison logique (LLC) lorsque la partie supérieure de la couche de liaison de données du modèle OSI.La norme originale développée par l' Institute of Electrical and Electronics Engineers (IEEE) en collaboration avec l' American National Standards Institute (ANSI) a été adoptée par l. IEEE 802.2 Last updated September 24, 2020. IEEE 802.2 is the original name of the ISO/IEC 8802-2 standard which defines logical link control (LLC) as the upper portion of the data link layer of the OSI Model. [1] The original standard developed by the Institute of Electrical and Electronics Engineers (IEEE) in collaboration with the American National Standards Institute (ANSI) was adopted by.

Working Group (WG) 802.2 developed the Logical Link Control (LLC) standard. WG 802.2 is officially disbanded. Its completed work was a published standard, variously designated ANSI/IEEE Standard 802.2, 1998 Edition, and ISO/IEC 8802-2:1998. In 2010, Standard 802.2 was withdrawn by the IEEE. Standards should refer to ISO/IEC 8802-2, which is stabilized (active but not updated), instead. LLC de type 2 : correspond à un service en mode avec connexion avec acquittement de données. LLC de type 3 : correspond à un service en mode sans connexion avec acquittement de données. La couche LLC définie en 802.11 utilise les mêmes propriétés que la couche LLC 802.2, et plus précisément celles de la LLC de type 2

IP datagrams are sent on IEEE 802 networks encapsulated within the 802.2 LLC and SNAP data link layers, and the 802.3, 802.4, or 802.5 physical networks layers. The SNAP is used with an Organization Code indicating that the following 16 bits specify the EtherType code. Normally, all communication is performed using 802.2 type 1 communication.

LLC désigne le standard IEEE 802 de couche Liaison, dont l'élaboration fut confiée à la sous-commision IEEE 802.2. Il se décline en trois versions LLC 1 - LLC 2 - LLC 3 présentant des différences de fiabilité. L'ensemble de ces trois versions s'interfacent à l'enemble des couches physiques This standard is part of a family of local area network (LAN) standards dealing with the physical and data link layers as defined by the ISO Open Systems Interconnection Reference Model. It describes the functions, features, protocol, and services of the logical link control (LLC) sublayer, which constitutes the top sublayer in the data link layer of the ISO 8802 Local Area Network Protocol IEEE 802.2 LLC; IEEE 802.2 LLC/SNAP; Ces différents types de trame ont des formats différents mais peuvent coexister et être distinguées entre elles [22] sur un même médium physique par les membres du réseau. La différence de base entre les trames Ethernet II et les autres trames est l'utilisation du champ de 16 bits (soit 2 octets) situé après les adresses MAC: En Ethernet II il est.

IEEE standard 802.2 defines Logical Link Control (LLC) as a data link control layer used on 802.3, 802.5, and other networks. IBM originally designed LLC as a sublayer in the IBM Token Ring architecture The IEEE 802.2 standard specifies the LLC sublayer for all IEEE 802 local area networks, such as IEEE 802.3/Ethernet (if the EtherType field is not used), IEEE 802.5, and IEEE 802.11. IEEE 802.2 is also used in some non-IEEE 802 networks such as FDDI. Etherne IEEE 802.2 LLC. General The IEEE 802.2 standard is identical for all network topologies. It provides a general interface between the different protocols (IPX, TCP/IP, etc.) and the different network types (Ethernet, Token Ring, etc.). The positioning within the OSI Reference model: 2: Data Link : LLC or LLC + SNAP: MAC: The LLC is responsible for the logical link functions of one or more. 802.2 Frame Format (LLC) Description. In the IEEE 802 reference model of computer networking, the logical link control (LLC) data communication protocol layer is the upper sublayer of the data link layer (layer 2) of the seven-layer OSI model. The LLC sublayer provides multiplexing mechanisms that make it possible for several network protocols (e.g. IP, IPX, Decnet and Appletalk) to coexist.

Two years later, when the final version of the 802.3 spec was released, it had been modified to include the 802.2 LLC Header, making NetWare's proprietary format incompatible. Finally, the 802.3 SNAP format was created to address backwards compatibility issues between Version 2 and 802.3 Ethernet. As you can see, the large number of players in the Ethernet world has created a number of.

802.2 was disbanded because their work is done; 802.2 was also published as ISO/IEC 8802-2, and the IEEE decided to withdraw the standard (perhaps there needs to be an active standards group for a non-withdrawn standard, and they didn't want to bother keeping the standards group around) La sous-couche de contrôle de la liaison logique (Logical Link Control en anglais, ou LLC) est la moitié haute de la couche de liaison de données du modèle OSI.

Service Access Ports (SAPs) SAPs are Service Access Ports. A SAP is a port (logical link) to the Network layer protocol.

For example, Unix's TCP/IP. IEEE 802.2 is the name given to a subsection of the IEEE 802 standard that describes a software component of a computer network.

I'll believe that the requirement for 802.2 might not have been clearly spelled out at some point, but I cannot believe that anyone on the 802.3 committee thought 802.3 didn't need a protocol descriminator, so I'm sure the intention was always for 802.2 to be required.)

The IEEE 802.2/803.3 LLC handling could be considered as a bug. Socket filters are not documented. The MSG_TRUNC recvmsg(2) extension is an ugly hack and should be replaced by a control message. There is currently no way to get the original destination address of packets via SOCK_DGRAM. See Also . socket(2), pcap(3), capabilities(7), ip(7), raw(7), socket(7) RFC 894 for the standard IP.

Like I said, 802.2 LLC can do many different things, including connection-oriented service with acknowledgement at layer 2 (yep! Go look THAT up!). Also, when talking 802.2 LLC, the OSI model data link layer is essentially divided into two sub-layers (LLC on top and MAC below) which you NEVER see in any training or books nowadays, but for the most part it boils down to a complex way to specify.
