4.2 OMI and the OSI network model

OMI provides the services described by levels 5 and 6 of the Open Systems Interconnect model. Level 5, the session layer, involves creating and terminating communication sessions between cooperating systems, while Level 6, the presentation layer, deals with data formats. These OMI services make the network transparent to applications (OSI level 7) for their remote database operations.

In turn, OMI relies on the virtual circuits of an existing OSI level 4 service to provide reliable sequential transmission of messages.

Successful communication with OMI depends on hardware and software to establish compatible protocols at level 4 and below, which are beyond the scope of this International Standard.
