Study Notes
Data Link Layer Responsibilities
- The Data Link Layer is responsible for providing reliable data transfer between two devices on the same network.
- The Data Link Layer is responsible for framing, error detection and correction, and flow control.
IEEE 802 LAN/MAN Data Link Layer
- The IEEE 802 LAN/MAN Data Link Layer is divided into two sublayers: Logical Link Control (LLC) and Media Access Control (MAC).
- The MAC sublayer is responsible for data encapsulation and media access control.
Logical Link Control (LLC) Sublayer
- The LLC sublayer provides services to the upper layers, including error detection and correction, flow control, and framing.
- The purpose of the LLC sublayer is to manage the communication between devices on the same network.
Media Access Control (MAC) Sublayer
- The MAC sublayer is responsible for handling the access to the network medium, resolving collisions, and allocating bandwidth.
- The MAC sublayer handles the physical addressing of devices on the network.
Network Arrangement
- The arrangement and layout of a network is referred to as the network topology.
Data Link Layer and Upper Layers
- The LLC sublayer of the Data Link Layer communicates between the networking software at the upper layers and the device hardware at the lower layers.
- The Data Link Layer allows upper layer protocols to access the network using a standardized interface.
