Virtual distributed environments for systems with time requirements

Virtualization is widely propagating technology that is used to run multiple virtual machines on the same computational unit by means of a piece of firmware, hardware or software called a hypervisor. Despite having been used since the 60as, the current indisputable need for fast reliable communication may put this technology to question. This project analyzes the amount of impact the virtualization has on the transmission times. In the first part, the Xen hypervisor, configured with different virtual environments, simulating complex scenarios, will be evaluated to determine the size of the impact. As a bridge between the multiple virtual machines, middleware Ice, will be used. Furthermore lower in the scale, for embedded systems, the XtratuM hypervisor was designed to support real-time systems. The second part is dedicated to evaluating whether the communication maintains the real time property of these systems. Bare boned virtualization will be implemented in this second part of the project.Ingeniería en Tecnologías de Telecomunicació
