4、vided by IHS under license with ANSINot for ResaleNo reproduction or networking permitted without license from IHS-,-,-This Technical Report is one in a series produced by the National Committee forInformation Technology Standards (NCITS). The secretariat for NCITS is held bythe Information Technolo

5、gy Industry Council (ITI), 1250 Eye Street, NW, Suite 200,Washington, DC 20005.As a by-product of the standards development process and the resources ofknowledge devoted to it, NCITS from time to time produces Technical Reports.Such Technical Reports are not standards, nor are they intended to be us

6、ed assuch.NCITS Technical Reports are produced in some cases to disseminate thetechnical and logical concepts reflected in standards already published or underdevelopment. In other cases, they derive from studies in areas where it is foundpremature to develop a standard due to a still changing techn

7、ology, orinappropriate to develop a rigorous standard due to the existence of a number ofviable options, the choice of which depends on the users particular requirements.These Technical Reports, thus, provide guidelines, the use of which can result ingreater consistency and coherence of information

8、processing systems.When the draft Technical Report is completed, the Technical Committee approvalprocess is the same as for a draft standard. Processing by NCITS is also similar tothat for a draft standard.CAUTION: The developers of this Technical Report have requested that holdersof patents that ma

9、y be required for the implementation of the Technical Report,disclose such patents to the publisher. However, neither the developers nor thepublisher have undertaken a patent search in order to identify which, if any, patentsmay apply to this Technical Report.As of the date of publication of this Te

10、chnical Report and following calls for theidentification of patents that may be required for the implementation of theTechnical Report, no such claims have been made. No further patent search isconducted by the developer or the publisher in respect to any Technical Report itprocesses. No representat

11、ion is made or implied that licenses are not required toavoid infringement in the use of this Technical Report.NCITSTechnicalReportSeriesPublished byAmerican National Standards Institute11 West 42nd Street, New York, New York 10036Copyright 2000 by Information Technology Industry Council (ITI)All ri
