DEFINITION

Classification: 714/1

RELIABILITY AND AVAILABILITY:

(under the class definition) Subject matter including means or steps for increasing a conditional probability of correctly performing services (e.g., data processing) throughout a time interval, given correct performance at the beginning of the interval, or for increasing the probability of correctly performing services at any given instant.

(1) Note. Classification in this array requires more than nominal recitation of data processing components in combination with means or steps for furthering correct data processing operations by mechanisms including error detecting, performance monitoring, fault locating, and fault recovery.

(2) Note. The species of reliability and availability directed to memory accessing and control with data archiving, backups, device access limiting, and security is classified elsewhere. See the SEE OR SEARCH CLASS notes below. Other species of reliability and availability in memory accessing and control such as isolating failed memory and storing redundant data are classified in this array.

(3) Note. Reliability features in a data processing control system are classified elsewhere.
