This Recommendation | International Standard defines ACSE services for ASO-association control in an open systems<\/p>\n
interconnection environment. ACSE supports two modes of communication service: connection-mode and<\/p>\n
connectionless-mode.<\/p>\n
The ACSE connection-mode service is provided by the use of the connection-mode ACSE protocol (see ITU-T<\/p>\n
Rec. X.227 bis <\/i>| ISO\/IEC 15954).<\/p>\n
The ACSE connectionless-mode service (A-UNIT-DATA) is provided by the use of the connectionless-mode ACSE<\/p>\n
protocol (see ITU-T Rec. X.237 bis <\/i>| ISO\/IEC 15955).<\/p>\n
Five functional units are defined in the ACSE. The mandatory Kernel functional unit is used to establish and release<\/p>\n
ASO-associations. The optional Authentication functional unit provides additional facilities for exchanging information<\/p>\n
in support of authentication during association establishment without adding services. The ACSE authentication<\/p>\n
facilities may be used to support a limited class of authentication methods. The optional ASO-context negotiation<\/p>\n
functional unit allows multiple ASO-contexts to be offered during association establishment. The optional higher level<\/p>\n
association functional unit provides for the facility to identify ASO-associations and transparently pass data to child<\/p>\n
ASOs and allows the ASO-context or the presentation context on an ASO-association to be modified during the lifetime<\/p>\n
of the association.<\/p>\n
This Recommendation | International Standard does not specify individual implementations or products, nor does it<\/p>\n
constrain the implementation of entities and interfaces within a computer system.<\/p>\n
