Information technology - Open Systems Interconnection - Connectionless protocol for the Application ...
This Recommendation | International Standard specifies:
a) procedures for the transfer of information among application-service-objects (ASOs); and
b) the abstract and concrete syntax for the representation of the A-UNIT-DATA ACSE APDU.
The A-UNIT-DATA procedure is defined in terms of:
a) The interactions between peer ACSE protocol machines by the use of a supporting service; and
b) the…
Information technology - Measurement and rating of performance of computer-based software systems
This International Standard defines how user oriented performance of computer-based software systems (CBSS)
may be measured and rated. A CBSS is a data processing system as it is seen by its users, e.g. by users at various
terminals, or as it is seen by operational users and business users at the data processing center.
A CBSS includes hardware and all its software (system software and…
Information technology - Requirements and Guidelines for Test Methods Specifications and Test Method...
Abstract: This International Standard defines the requirements and
guidelines for test method specifications and test method implementations
for measuring conformance to POSIX standards. Test specification
standard developers for other Application Programming Interface (API)
standards are encouraged to use this standard. This document is aimed
primarily at developers and users of test method…
Information technology - Elements of management information related to the OSI Physical Layer
This Recommendation | International Standard provides the specification of management information within an Open
System related to those operations of the OSI Physical Layer specified by the specifications in this Recommendation |
International Standard. Specifics on how Physical Layer management is accomplished is beyond the scope of this
Recommendation | International Standard. Physical Layer…
1 Scope
1.1 This Standard specifies the requirements for insulating tubing that is
usually round in cross-section and that consists entirely of extruded compounds
whose characteristic constituents are thermosetting, elastomeric, or
thermoplastic polymers (see Table 1 for materials and ratings). These
requirements also cover heat-shrinkable and cross-linked tubing.
1.2 Tubing is…
Information technology — Message Handling Systems (MHS): MHS Routing — Guide for messaging systems m...
This Recommendation | Technical Report specifies the means by which the administrator of various aspects of an MHS
system may configure information into the directory for MTAs to use to determine the routing of messages.
ITU-T Rec. X.412 | ISO/IEC 10021-10 provides a set of directory structures that may be configured in many different
ways to support a particular MHS routing strategy. In order to…
Information technology — Message Handling Systems (MHS): Message store: Abstract service definition ...
This Recommendation | International Standard defines the Message Store abstract-service. This abstract-service is
provided by the Message Store access protocol (specified in ITU-T Rec. X.419 | ISO/IEC 10021-6) in conjunction with
the MTS abstract-service (defined in ITU-T Rec. X.411 | ISO/IEC 10021-4), together with the Remote Operations
Service Element (ROSE) services (defined in ITU-T Rec. X.…
Information technology — Message Handling Systems (MHS): Electronic Data Interchange Messaging Syste...
This Recommendation | International Standard is one of a series on message handling. The entire set provides a
comprehensive blueprint for a Message Handling System (MHS) realized by any number of cooperating open systems.
The purpose of an MHS is to enable users to exchange messages on a store-and-forward basis. A message submitted on
behalf of one user, the originator, is conveyed by the…
Information technology — Message Handling Systems (MHS): MHS routing — Part 10:
This Recommendation | International Standard specifies the means by which messages are routed through the MHS, and
supplements the procedures defined in 14.3 of ITU-T Rec. X.411 | ISO/IEC 10021-4.
Other Recommendations | parts of ISO/IEC 10021 define other aspects of the MHS. ITU-T Rec. F.400/X.400 | ISO/IEC
10021-1 defines the user-oriented services provided by the MHS. ITU-T Rec. X.402 | ISO/…
