Abstract


Remote labs in difference to virtual labs allow as usual only a single user access. To manage the user access for such remote experiments a reservation system is used. The aim of this work is to develop a simultaneous multi user access to the lab server and the remote experiment. This approach was tested for the READ remote lab and a Microcontroller remote lab, installed at the CUAS. The system controlled by LabView has been implemented using a Data Acquisition Card from National instruments. The performance of the simultaneous access was tested under load with a variable number of users. For the MRL a queue gives access to the peripherals to the main user, while the others wait for their time slot to use the system. This was implemented in such a way due to the synchronous characteristics of this lab.
