System fault tolerance is a feature that helps any system continue to work even if one of its parts fails. This will reduce the level of performance, but the system will not completely fail.

One such system is TPC/IP, which was designed to keep off uninterrupted two-way communication between network devices if they are extremely loaded or do not respond to requests. The design of the systems allows users to ensure availability not only during unintended failures but also during the maintenance period.

Fully fault-tolerant design as a way to ease the routine

Fully fault-tolerant design is used in many fields of activity. Modern people often use this when performing significant procedures such as:

  • air travel;
  • research centers;
  • banking;
  • research work.
Air travel

Fully fault-tolerant design performs such functions as:

  1. Replication. Errors cannot disrupt some uninterrupted data transmission processes due to the fact that several instances of the same system function via a mirror system.
  2. Variety. Failure of one item in the system will result in the automatic connection of a copy of this system, which will be used for testing in the new environment without outside interference with the correctness of the work.
  3. Continuity. In the absence of a fault-tolerance system, complete abandonment of component parts control occurs. This helpful feature helps different components to communicate with copies of those parts of the system that have failed.
  4. Backup. Copies are not created in one but in more than one place, which further increases the security of work even in case of critical failures.
  5. Reliability. End users will be able to get service regardless of failures. All transmitted information will reach the end point without loss.
  6. Security. Each level of the system must be prepared for critical errors resulting from malware, third-party intrusions, and hacks.
  7. Intelligent System Development. Each system is equipped with tools to analyze its environment, which allows it to adapt to the working environment to maintain optimal conditions. As a result, even complete isolation will not cause the unit to stop working. Also, suppose a fault occurs in a particular partition, resulting in no connection to the rest of the system. In that case, the built-in mechanisms will be able to detect the fault without third-party assistance.
  8. Lack of any point at which the system falls into error. If the work uses different components, the problem in one of these points will not cause a complete failure.
  9. System revert. There is a real possibility of developing several points of system versions to which you can return in the event of a complete system failure and the failure to recover its functioning. Then, all changes made will be canceled, and the program will be capable of continuing its correct work.
  10. Support for multitasking. Any system can receive and process data in an unlimited large stream. Because of this, even an overloaded environment will not cause any errors and change the transmitted information.

System fault tolerance is a set of functions that prevent any factor from disrupting the transmission of data that is important to the operation of the object. If banks did not use this technology, the network disruption would result in the loss of data about transactions being conducted at that time. It lacks track information for aviation, but this development is also used in other areas of human activity. We must remember that this technology brings us more comfort and ergonomics, and humanity would have progressed much slower without this unique technology.
