Adaptive modular recovery block

Achieving ideal fault tolerance capabilities in distributed systems is an increasing stipulate. The paper provides reader with general understanding of fault tolerance and enlightens various software fault tolerance models for design faults. Component based recovery block (CBRB) divides systems into modules and check for their reliability separately but lacks to explain integration issues that can cause instability. The proposed model addresses this unattended issue of CBRB to enhance the reliability of software.
