Record and reply messages in real time systems

Abstract EN

Many applications with real-time demands are composed of mixed sets of tasks with a variety of requirements.

These can be used in the form of standard timing constraints or flow of data.

Therefore you need real time multitasking operating system to guarantee within a fixed amount of time.

Scheduling Algorithm for real-time multitask operating system is implemented according to the priority of tasks depending on nature of their jobs and need to resource or time.

The Scheduling algorithm which used here is event driven, not clock driven.

It is necessary in data communication system which is an example of real time system to record the received messages for documentation and for further use like for simulation or computation or reply them.

The time which saved with each message is important to be close to the real situation.

The system is written in C++ programming language under DOS environment.
