22、*X=882 94 4862593 0633927 3TB Introduction Remote operations (ROS) is a paradigm for interactive communication between objects. As such it can be used in the design and specification of distributed applications. The basic interaction involved is the invocation of an operation by one object (the invo
23、ker), its performance by another (the performer), possibly followed by a report of the outcome of the operation being returned to the invoker. The concepts of ROS, as specified in IT-T Rec. X.880 I ISOAEC 13712-1, are abstract, and may be realized in many ways. For example, objects whose interaction
24、s employ ROS concepts may be Feparated by a software interface or by an OS1 network. ITU-T Rec. X.881 I ISO/IEC 13712-2 provides the framework for the realization of an association contract as an OS1 application context. Such an application context is specified primarily in terms of a collection of
25、application service elements. From a ROS perspective, these ASEs fall into three broad categories: a) b) c) operation-specific ASEs, which embody knowledge of the definitions of the operations in the contract; the Remote Operations ASE (ROSE) which drives the general-purpose protocol required to inv
26、oke and report returns of arbitrary operations; information transfer ASEs concerned with the establishment and release of associations where necessary, and the communication of the ROSE protocol information. This Recommendation I International Standard describes the behaviour of ROSE itself, and the
27、 way in which different collections of information transfer ASEs (specifically, the Reliable Transfer Service Element (RTSE) and the Association Control Service Element (ACSE) are employed to transfer its protocol control information (KI) in an OS1 realization. This Recommendation I International St
28、andard is a revision of CCITT Rec. X.229 I ISO/IEC 9072-2. The existing usage of ROSE in conjunction with ACSE. RTSE and the Presentation layer as defined in CCIT Rec. X.229 I ISO/IEC 9072-2 remains valid after this revision. In addition, this revision makes no change to the ROSE PCI. Annex A forms
