20、on I International Standard provides the Protocol Implementation Conformance Statement (PICS) proforma for the Reliable Transger protocol specified in Recommendation X.228 (1988). The PICS proforma presents in tabular form the mandatory and optional elements of the Reliable Transfer protocol. Introd

21、uction This Recommendation 1 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 Recommendations and International Standards in the set as defined by the Reference Mod

22、el for Open Systems Interconnection (see IT-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 size. The goal of Open Systems Interconnection is to allow, with a minimum of techni

23、cal agreement outside the interconnection standards, the interconnection of information processing systems: - from different manufacturers; - under different managements; - - of different technologies. of different levels of complexity; and The Reliable Transfer Service Element (RTSE) is an applicat

24、ion-service-element commonly used by a number of applications. RTSE provides for the reliable transfer of Application Protocol Data Units (APDUs) between open systems. It provides an application-independent mechanism to recover from communication and end-system failure minimizing the amount of retra

25、nsmission. 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 Conformance Statement (PICS). This Recommendation I International Standard

26、includes the PICS proforma for the reliable transfer protocol as defined in CCITT Rec. X.228 (1988) I ISO/IEC 9066-2:1989. . ITU-T Rec.

X.228 I ISOIIEC 9066-2 with a consistent means of stating which capabilities have been implemented. The proforma is in the form

47、 of a questionnaire and consists of a 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

48、 status value specifying the support 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. Purpose and structure of the proforma Subclause A.3 is for identification of the implementation

49、. Subclause A.4 contains the means of specifying, at a high level, the protocol 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 A.2.2.1 Introduction Notations have been introduced in order to reduce the size of tables in the PICS proforma.
