In the distributed real time systems, tasks must meet their deadline even in the presence of hardware/software faults. Fault tolerance in distributed real time systems refers to the ability of the system to meet the tasks deadline and to detect their failure and recover them. In this paper, we considered the problem of fault tolerance and developed a fault tolerance protocol called DRT-FTIP (Distributed Real Time – Fault Tolerance Integrity Protocol).This protocol increases the integrity of the scheduling in distributed real time systems.
