ITU-T RECMNxX.249 95 4862591 Ob33327 040 m Summary This Recommendation I International Standard provides the Protocol Implementation Conformance Statement (PICS) proforma for the Remote Operations protocol specified in Recommendation X.229 (1988). The PICS proforma presents in tabula

18、r form the mandatory and optional elements of the Remote Operations protocol. Introduction This Recommendation I International Standard is one of a set of Recommendations I International Standards produced to facilitate the interconnection of information processing systems. It is related to other Re

19、commendations and Intemational Standards in the set as defined by the Reference Model for Open Systems Interconnection (see ITU-T Rec. X.200 I ISO/IEC 7498-1). The Reference Model subdivides the area of standardization for interconnection into a series of layers of specification, each of manageable

20、size. The goal of Open Systems Interconnection is to allow, with a minimum of technical agreement outside the interconnection standards, the interconnection of information processing systems: - from different manufacturers; - under different managements; - - of different technologies. of different l

21、evels of complexity; and The Remote Operations Service Element (ROSE) is an application-service-element commonly used by a number of applications. ROSE supports interactive applications in a distributed open systems environment. A Remote Operation is requested by one entity; the other entity attempt

22、s to perform the Remote Operation and then reports the outcome of the attempt. To evaluate the conformance of a particular implementation, it is necessary to have a description of the capabilities and options which have been implemented. Such a description is called a Protocol Implementation Conform

42、lementors Guide version: A.2 Instructions A.2.1 The purpose of this PICS proforma is to provide suppliers of implementations of CCIT Rec. X.229 I ISOEC 9072-2 with a consistent means of stating which capabilities have been implemented. The proforma is in the form of a questionnaire and consists of a

43、 set of items. An item is provided for each capability for which an implementation choice is allowed. Items are also provided for major mandatory capabilities for which no implementation choice is allowed. Each item includes an item number, an item description, a status value specifiing the support

44、requirement, and room for a support answer to be provided by the supplier. This subclause provides general information and instructions for completion of the proforma. Subclause A.3 is for identification of the implementation. Subclause A.4 contains the means of specifying, at a high level, the prot

45、ocol and corrigenda that have been implemented. Subclause AS contains the global statement of conformance. Subclauses A.6 onwards contain tables in which the supplier specifies details of the implementation options chosen. A.2.2 Symbols, terms and abbreviations Purpose and structure of the proforma

46、A.2.2.1 Introduction Notations have been introduced in order to reduce the size of tables in the PICS proforma. These have allowed the use of multi-column layout where the columns are headed Status, and Support. The definition of each are given below. Additionally, the following definitions apply: A

47、.2.2.1.1 (PICS) item: A row in a PICS proforma table. A.2.2.1.2 (PICS) question: The question to be answered in the intersection of a PICS item and either a support column (i.e. “Is this item supported in the context applying to this table and column”) or supported values column (i.e. What values ar

48、e supported for this item in the context applying to this table and column”) in a PICS proforma table. A.2.2.1.3 status (value): An allowed entry in the status column for an item in a PICS proforma table. Copyright release for PICS proforma: Users of this Recommendation I International Standard may
