Abstract :
Abstract - Embedded devices have been recently connected
to the Internet, enabling their management and monitoring
from the Web. Although Web interfaces can bring several
advantages to embedded systems, from designers to endusers,
re-designing legacy systems in most cases may not be
the most effective way to upgrade a system to the Internet. In
this paper, a hardware/software architecture is presented for
an embedded proxy agent to add Internet-awareness to an
existing design. An approach to add graphical user interfaces
through the Web is presented as well. This paper deals with
different approaches and solutions for enabling network
connectivity in the embedded systems domain. Furthermore
an RTOS based open software architecture is introduced in
order to realize flexible applications with functional and non
functional requirements on network and internet
connectivity. The main advantage of this “open solution” in
comparison to plug & play solutions is that the desired
network functionality can be customized, even if it is
necessary to extend or violate some network protocol
standards, which is not unusual in embedded system
applications due to specific constraints and limitations.In the
last few years there has been an increasing demand for the
connection of embedded systems to the Internet for the
purposes of monitoring and management of these devices.
Embedded systems are systems implementing specific
functions, such as printers, household devices,
communication devices, avionics, medical instruments, and
process control systems. The connection of embedded systems
to the network enables the replacement of traditional and
proprietary user interfaces to standard Internet interfaces,
such as the use of familiar Web browsers from any desktop.
