feilkø

A feilkø, often translated as error queue or fault queue, is a data structure used in computer science and telecommunications to manage and process errors. Its primary function is to store error conditions or messages that have occurred within a system. When an error is detected, instead of immediately halting the program or causing a failure, the error information is placed into the feilkø.

This approach allows the system to continue operating, albeit potentially in a degraded state, while the errors are handled separately. The feilkø can be processed by a dedicated error handling routine or module. This routine can then decide on the appropriate action, which might include logging the error, attempting to retry the failed operation, notifying an administrator, or gracefully shutting down a specific component.

The use of a feilkø promotes system stability and resilience. It decouples the detection of errors from their resolution, preventing cascading failures. This is particularly important in complex systems where a single minor error should not bring down the entire application. Different implementations of feilkøs can exist, varying in their ordering policies (e.g., FIFO, LIFO) and the type of information they store. The design choice depends on the specific requirements of the system and the nature of the errors being managed.
