信息技术.开放系统互连.基本参考模型:基本模型

[中文适用范围]： 取消并取代第一版（1984 年）。 该模型为协调标准开发以实现系统互连提供了共同基础，同时允许将现有标准置于整体参考模型中。 该模型确定了制定或改进标准的领域。 它无意充当实现规范。 [外文原描述]： Cancels and replaces the first edition (1984). The model provides a common basis for the coordination of standards development for the purpose of systems interconnection, while allowing existing standards to be placed into perspective within the overall Reference Model. The model identifies areas for developing or improving standards. It does not intend to serve as an implementation specification.
