ALEXANDRIA, Va., June 9 -- United States Patent no. 12,289,209, issued on April 29, was assigned to Amazon Technologies Inc. (Seattle).

"Managing network capacity based upon simulation of failures of network devices" was invented by John William Evans (Frome, Great Britain) and Ahmed Elmokashfi (Bellevue, Wash.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A system is described that combines outputs of network simulations, which are used for capacity planning, with empirical data of network element failure probabilities, to produce what traffic utilization is needed for each network device interface to achieve a specified availability target. Utilization of each interface can be captured for each failure ca...
