Nosaukums<p>This Recommendation | International Standard defines ACSE services for ASO-association control in an open systems</p> <p>interconnection environment. ACSE supports two modes of communication service: connection-mode and</p> <p>connectionless-mode.</p> <p>The ACSE connection-mode service is provided by the use of the connection-mode ACSE protocol (see ITU-T</p> <p>Rec. X.227 <i>bis </i>| ISO/IEC 15954).</p> <p>The ACSE connectionless-mode service (A-UNIT-DATA) is provided by the use of the connectionless-mode ACSE</p> <p>protocol (see ITU-T Rec. X.237 <i>bis </i>| ISO/IEC 15955).</p> <p>Five functional units are defined in the ACSE. The mandatory Kernel functional unit is used to establish and release</p> <p>ASO-associations. The optional Authentication functional unit provides additional facilities for exchanging information</p> <p>in support of authentication during association establishment without adding services. The ACSE authentication</p> <p>facilities may be used to support a limited class of authentication methods. The optional ASO-context negotiation</p> <p>functional unit allows multiple ASO-contexts to be offered during association establishment. The optional higher level</p> <p>association functional unit provides for the facility to identify ASO-associations and transparently pass data to child</p> <p>ASOs and allows the ASO-context or the presentation context on an ASO-association to be modified during the lifetime</p> <p>of the association.</p> <p>This Recommendation | International Standard does not specify individual implementations or products, nor does it</p> <p>constrain the implementation of entities and interfaces within a computer system.</p> <p>No requirement is made for conformance to this Service definition.</p>
