The c
8、ontest of Functional Standardization is one arca in the overall lield of Information Technology (IT) standardization activities. covering base standards. profiles. and registration mechanisms. A profile defines a combination of base standards that collcctivcly perform a specific well-defined IT func
9、tion. Profiles standardize the use of options and other variations in the base standards, and provide a base for the development of uniform, internationally recognized system tests. ISPs arc produced not simply to “lcgitimizc” a particular choice of base standards and options, but to promote real sy
10、stem intcropcrability. One of the most important roles for an ISP is to serve as the basis for the development (by organizations other than IS0 and IEC) of internationally recognized test methods. The development and widcsprcad acccptancc of tests based on this and other ISPs is crucial to the succe
11、ssful reahsation of this goal. ISO/IEC ISP 12067 consists of scvcral parts, of which this is Part 4. lSO/IEC ISP 12067-I specifics the profile requirements that arc subnctwork-indcpcndcnt. Thcrc are further parts which specify subnctworkdcpendent and mediadepcndcnt rcquircmcnts. In addition. for eac
12、h individual profile there is a part of ISO/IEC ISP 12067 which idcntiIics the specific rcquircmcnts of that profile. making refcrencc to appropriate material from part 1 and from the subnctworkdcpcndcnt parts. iv Copyright International Organization for Standardization Provided by IHS under license
