The PDU is passed to layer N−1, where it is known as the service data unit (SDU). At layer N−1 the SDU is concatenated with a header, a footer, or both, producing a layer N−1 PDU. It is then passed to layer N−2. The process continues until reaching the lowermost level, from which the data is transmitted to the receiving device.
The network layer provides the means of transferring variable-length network packets from a source to a destination host via one or more networks. Within the service layering semantics of the OSI (Open Systems Interconnection) network architecture, the network layer responds to service requests from the transport layer and issues service requests to the data link layer.
layers 3 Network: Packet: Structuring and managing a multi-node network, including addressing, routing and traffic control: 2 Data link: Frame: Transmission of data frames between two nodes connected by a physical layer 1 Physical: Bit, Symbol: Transmission and reception of raw bit streams over a physical medium
This article lists protocols, categorized by the nearest layer in the Open Systems Interconnection model.This list is not exclusive to only the OSI protocol family.Many of these protocols are originally based on the Internet Protocol Suite (TCP/IP) and other models and they often do not fit neatly into OSI layers.
In a network using Open Systems Interconnection (OSI) architecture, the physical signaling sublayer is the portion of the physical layer that [7] [8] interfaces with the data link layer's medium access control (MAC) sublayer, performs symbol encoding, transmission, reception and decoding and, performs galvanic isolation.
Protocol data units of the OSI model are: [1] The Layer 4: transport layer PDU is the segment or the datagram. The Layer 3: network layer PDU is the packet. The Layer 2: data link layer PDU is the frame. The Layer 1: physical layer PDU is the bit or, more generally, symbol.
