资源共享与站间通讯是计算机联网的主要目的。根据局部网特点,借助于虚拟卷思想,本文提出了把上述两种应用融为一体的新的应用方式一工怍站间交叉调用。首先给出了局部网虚拟卷思想,然后详细地阐述了站间交叉调用的设计实现方法和安全性考虑。 Resource sharing and communication between stations is the main purpose of computer networking. According to the characteristics of the local area network, with the help of the virtual volume idea, this paper proposes a new application mode that combines the above two applications. First of all, it gives the idea of ​​local network virtual volume, and then elaborates the design and implementation methods and security considerations of inter-station cross-calling.
