Welcome to VDD-Project.org: The official Virtual Distro Dispatcher Project website. |
|
 Virtual Distro Dispatcher is an innovative way for Linux distributions dispatching for LAN environment.  This project was born from the degree thesis of Flavio Bertini, student of Master degree at the Department of Computer Science (DIS) - Sapienza University of Rome. Davide Lamanna manages all the project activities suggesting new solutions and providing a lot of new ideas to improve VDD much more. The main VDD's feature, is its Trashware based laboratory. This research1 started setting up a lot of obsolete hardware coming from old PCs trashing activites of companies. A lot of people supplied a huge quantity of old PCs for free. Trashware groups, helped VDD to become a costless distributed environment, whose aim is to supply for Internet access, word processing software and many other things to that people which cannot afford a new workstation. Trashware gave also the possibility to realize both teaching and development environment especially using Open Source software and Operating Systems like GNU/Linux. 1. The research is going ahead in cooperation with Ing. Davide Lamanna - Department of Computer Science at "Sapienza" University of Rome |

Since XEN has been introduced by Salvatore Cristofaro, an accurate performance analysis has been performed, to show how it is convenient respect of UML. Read more ... |

Salvatore Cristofaro joined the VDD Project. Welcome Salvatore. He is a student like me who decided to contribute in the VDD Project development. During his stage period (still in progress) at the Dipartimento di Informatica e Sistemistica "Antonio Ruberti", he brought a large contribute to this research. He gave VDD the possibility to experiment new alternatives to UML, such as Xen, and he studied many possibilities to speed up the whole system also setting up a RAID architecture. With his precious contribute we were able to rebuild VDD in another Computer Laboratory at the our Department of Computer Science. New workstations support the overall system and VDD's performances are increased actually. Now we have two last generation Gentoo Linux based Server, a Gigabit Ethernet LAN and a few thin clients to make tests. We are also studying for a HPC Clustering system to be applied to VDD even though there are many difficulties in finding the right one which fits our necessities. Also the LTSP configuration files have been updated with new entries, especially the dhcp server configuration file. You may contact Salvatore through the Contacts section. |

A new implementation of VDD has been released.
It's now possible to project operating system other than Linux on terminals since the introduction of XEN.
Respect of the previous version of VDD, which could virtualize and dispatch only Linux distributions, now it grants to choice many other operating systems such as Windows and Open Solaris or even better ReactOS. These targets have been reached thanks to the utilisation of XEN virtualization system. The possibility to dispatch other operating system is not the only innovation. Actually, VDD is now able to benefits of new hardware virtualization technologies supplied from Intel and AMD (VT-x and AMD-v). |
