ISA100 and the OSI Model

The OSI Model

ISA100 Technology and Benefits by Layer

Physical (1-PHY)

Defines the electrical and physical specifications for devices, particularly the relationship between a device and a transmission medium.

Technology

Benefits

Data Link (2-DLL)

Provides the means to transfer data between network entities and to detect and possibly correct any errors that may occur in the Physical Layer.

Technology

Benefits

Network (3-NL)

Provides transparent transfer of data between end user applications.

Technology

Benefits

Transport (4-TL)

Provides the means of transferring variable length data sequences from a source to a destination via one or more networks; performs network routing functions.

Technology

Benefits

Session (5-SL)

Controls the dialogues (connections) between computers.

It establishes, manages, and terminates the connections between the local population and the remote application.

Technology

Benefits

Presentation (6-PL)

Establishes a context between Application Layer entities, in which the higher-layer entities may use different syntax and semantics.

Technology

Benefits

Application (7-AL)

Interface with software applications that implement a communicating component.
