The ISO Association Control Service Element (ACSE), an application layer
protocol in the OSI model, is to establish and release an application-association
between two AEIs and to determine the application context of that association.
The ACSE supports two modes of communication: connection-oriented and
connectionless. For the connection-oriented mode, the application-association is
established and released by the reference of ACSE connection oriented services.
For the connectionless mode, the application-association exists during the
invocation of the single ACSE connectionless mode service, A-UNIT-DATA.
The ISO Remote Operations Service Element Protocol (ROSE) is a protocol that
provides remote operation capabilities, allows interaction between entities in a
distributed application, and upon receiving a remote operations service request,
allows the receiving entity to attempt the operation and report the results of the
attempt to the requesting entity. The ROSE protocol itself is only a vehicle for
conveying the arguments and results of the operation as defined by the
application.
