In the last two decades, with the
rapid advances in hardware,software and networks, the computing paradigm
has shifted from mainframe computing to the desktop (PC)
computing, and then now the pervasive computing
(Post-PC), in which devices are diverse and support
users to finish their tasks without distraction. Thus,
in a user point, we are moving away from a hardware or
software-centric view of computing to a more
service-oriented perspective, i.e. users simply just
accomplish their tasks on their data and don’t care
about the machine specifics and management details.
Transparent computing, in some sense, is a concrete form
of pervasive computing. Conceptually, transparent
computing is such a computing paradigm that in which
users are not aware of the software, like operating
system, supporting tools and applications, but can
demand their needed services, which are stored,
administrated and managed in centric servers, to
accomplish their computing tasks, from any types of
devices, for example, personal computer, laptop
computer, mobile intelligent device and intelligent
We have implemented Transcom system
based on the concept of Transparent computing, which can
support transparent desktop computing. This innovative
system’s main features are as follows:
1. The client doesn’t store any OS
(Operating System) and application software locally.
Instead, it downloads them from the server when powered
on and run programs locally according to user’s command.
This paradigm alleviates the burden of the server and
leverages the client’s local resources.
2. Multi-OS Remote Booting Protocol (MRBP)
enables users to download OS kernel and applications
from the server through Ethernet.
3. Virtual Swapping and Scheduling
algorithms make high-efficient resources sharing
4. The client system supports X86
instruction set and multiple peripheral equipments.
The cost of hardware is as low as
5. Three Chinese patents have been
approved related to this system.
6. Products based on this paradigm
are being manufactured by three companies including
Lenovo, the biggest computer manufacturer in China.
7. The system has wide potential
applications including military, education,
e-government, enterprise, finance, etc.
