Application Service Element definition networking
(ASE) Software in the presentation layer
of the OSI
seven layer model which provides an abstracted interface layer to service application protocol data units (APDU). Because applications
vary, ASEs are split into common services and specific services.
Examples of services provided by the common application service element (CASE) include remote operations (ROSE) and database
concurrency control and recovery (CCR).
The specific application service element (SASE) provides more specialised services such as file transfer, database access, and order entry.
