18.5 Summary and Conclusions
Distributed systems can use existing resources much more efficiently.
We show that system natural or deliberately introduced redundancy can be used
for reconfigurability.
Reconfigurability can serve for performance, reliability and energy-efficiency
and if widely used be even traded for all three mentioned properties.
An extended generalized algorithm of threat handling using introduced resources
is proposed and explained.
Distributed computer systems require own algorithms of threat handling that
consider property of “distributiveness”, two of them: forward and backward tracing
ones are explained and evaluated.
Both algorithms are proven to be the most efficient to define damaged areas as
soon as possible (ASAP) and as local as possible (ALAP).
A system availability applying described algorithms is estimated, showing great
improvement of real-timeness.
