The link layer corresponds to the OSI data link layer and may include similar functions as the physical layer, as well as some protocols of the OSI's network layer. These comparisons are based on the original seven-layer protocol model as defined in ISO 7498, rather than refinements in the internal organization of the network layer.
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.
OSI model Layer Protocol data unit (PDU) Function [3]; Host layers 7 Application: Data: High-level protocols such as for resource sharing or remote file access, e.g. HTTP. 6

EtherNet/IP uses both of the most widely deployed collections of Ethernet standards –the Internet Protocol suite and IEEE 802.3 – to define the features and functions for its transport, network, data link and physical layers. EtherNet/IP performs at level session and above (level 5, 6 and 7) of the OSI model. CIP uses its object-oriented ...
The RapidIO transport layer supports any network topology, from simple trees and meshes to n-dimensional hypercubes, multi-dimensional toroids, and more esoteric architectures such as entangled networks. The RapidIO transport layer enables hardware virtualization (for example, a RapidIO endpoint can support multiple device IDs).
Profinet implements the interfacing to peripherals. [1] [2] It defines the communication with field connected peripheral devices.Its basis is a cascading real-time concept. Profinet defines the entire data exchange between controllers (called "IO-Controllers") and the devices (called "IO-Devices"), as well as parameter setting and diagnosi
In the United States, two military standards govern the use of combat net radios and the host applications that communicate over the network: MIL-STD-188-220 and MIL-STD-2045-47001. In addition to IETF RFCs governing UDP, TCP, and IPv4/IPv6, all seven layers of the OSI communications architecture are addressed.
