Abstract: Provided are techniques at least two pairing strategies in a contact center system, involving a method, a system and an article of manufacture. The method of present disclosure includes: assigning sequence numbers to a series of events; initiating a first pairing strategy based on the sequence numbers; ending the first pairing strategy based on the sequence numbers; initiating a second pairing strategy based on the sequence numbers; ending the second pairing strategy based on the sequence numbers; assigning a first set of values to contacts assigned by the first pairing strategy; assigning a second set of values to contacts assigned by the second pairing strategy; and determining a metric that compares the first pairing strategy with the second pairing strategy based on the first and second set of values. The techniques of present disclosure can get rid of shortcomings and/or drawbacks of a time-based benchmark.

Abstract: An improved power fail-safe has an effective maximum delay of two gate delays from an input operably powered by a first power supply to a first and a second output operably powered by a second power supply. The first and second outputs have predetermined values during an interval when the first power supply has failed and the second power supply is active. The first and second power supplies may be based at least in part on different power domains. The first power supply may be based at least in part on a core power domain and the second power supply may be based at least in part on an I/O power domain.
