OSI reference model – ISO 11898-1/2 Figure 1: OSI reference model [1] The Layered Architecture according to the OSI Reference Model specified in the ISO 11898-1 is the same for both CAN 2.0 and CAN FD (shown in Figure 1). The differences within the OSI Reference Model between CAN 2.0 and CAN FD are in the Logical Link Control (LLC) and the Medium

Layered Architecture of CAN FD according to the OSI Reference Model The scope of this specification is to define the MAC sublayer and a small part of the LLC sublayer of the Data Link Layer as well a part of the Physical Layer and to describe the consequences of the CAN protocol on the surrounding layers.

OSI Reference Model - Router Alley

OSI Reference Model The Open Systems Interconnection (OSI) model was developed by the International Organization for Standardization (ISO), and formalized in 1984. It provided the first framework governing how information should be sent across a network. The OSI model consists of seven layers, each corresponding to a specific network function:

Asynchronous Transfer Mode (ATM)

The ATM protocol reference model is based on standards developed by the ITU. Communi-cation from higher layers is adapted to the lower ATM defined layers, which in turn pass the information onto the physical layer for transmission over a selected physical medium. The protocol reference model is divided into three layers: the ATM adaptation ...

INTRODUCTION TO PROFIBUS DP - Unict

the OSI (Open System Interconnection) reference model per international standard ISO 7498. In this model, every layer handles precisely defined tasks. Layer 1 of this model is the physical layer and defines the physical transmission characteristics. Layer 2 is the data link layer and defines the bus access protocol.

OSI Seven Layer Model. When we talk about Layer 2 and Layer 3 networking, it is these layers that we’re referring to, and logically the further up the OSI model we move, the greater intelligence we can use in networking decisions. Each layer plays its part in moving data from one device to another across a net-

The LIN physical layer is independent of higher OSI model layers (e.g., the LIN protocol). Consequently, nodes containing an ISO 17987-compliant physical layer can be combined, without restriction, with LIN physical layer nodes that comply with earlier revisions (LIN1.0, LIN 1.1, LIN 1.2, LIN 1.3, LIN 2.0, LIN 2.1, LIN 2.2 and LIN 2.2A).
