1.1 Hard Real Time vs. Soft Real Time Hard real time systems and soft real time systems are both used in industry for different tasks [15]. The primary difference between hard real time systems and soft real time systems is that their consequences of missing a deadline dif-fer from each other. For instance, performance (e.g. stability) of a hard real time system such as an avionic control .
6 Real Time Constraints Many Embedded Systems must meet real-time constraints zA real-time system must react to stimuli from the controlled object (or the operator) within the time interval dictated by the environment. zFor real-time systems, right answers arriving too late are wrong. Frequently connected to physical environment through sensors and actuators.
This paper describes the implementation of real-time network extension based on embedded Linux. Compared with different solution of achieving real-tine ability on Linux system, Xenomai and Rtnet have been chosen in our system. Finally, the real-time performance test has been

The network embedded system is a fast growing area in an embedded system application. The embedded web server is such a system where all embedded device are connected to a web server and can be accessed and controlled by any web browser. Examples; a home security system is an example of a LAN networked embedded system .
