Summary:目前高校计算机实验室老化，性能下降，故障率高，严重影响计算机实验教学效果。学校经费有限，无力全面更新。故须选择既能满足实验教学要求．又可节省经费的途径。基于PXE无盘网络实验系统，结合云技术，以服务器和交换机为核心，将旧计算机实验室改造成无盘网络实验室。在投入较少经费前提下，硬件性能提高100倍，软件性能提高200倍，综合性能提高20000倍，完全满足实验教学要求。云技术无盘实验教学系统，既可节省经费投入，又能使老旧机房重换生机，值得大力推广应用，

For a lot of computer laboratories of colleges and universities, their computers already are outdated, low performance and high failure rate happen with the lapse of time. But no enough money can be invested to renew these computers. So a good cost performance method has to be found. The PXE diskless experiment system based on the cloud technology can solve this problem very well. Server and switch are kernel. With small investment, the single-alone computer laboratory is reformed into diskless network experiment system. The performance of hardware increases 100 times, the performance of software increases 200 times and the integrated performance of laboratory increases 20 000 times. The diskless network laboratory meets experiment demand. This method is worth expanding vigorously.
