在嵌入式虚拟磁带库(VTL)的设计中，应用程序与内核之间的通讯是一个核心问题。本文提出了基于共享磁盘和共享内存的应用程序与内核之间的通讯方案，实现了嵌入式虚拟磁带库中的用户界面和SCSI 控制器之间可靠的消息传递。实验表明，该通讯解决方案是可行的。

Design of information communication between user space and kernel on virtual tape library based on embedded technology Xuan Zhao, Xuelei Xu, Jianwei Xing, Hong Liu （Tsinghua University, Beijing 100084） Abstract: Communication between application and kernel is a key problem in the design of virtual tape library (VTL) based on embedded technology. This paper brings forward a solution based on shared disk and memory, which can transfer message between user interface and SCSI controller reliably.
Experiments indicate that our solution is feasible.
