Patent ID: 7610377

Claim:
A method of managing overload in a server system, having a service operating in response to input requests, and a server operation parameter related to the operation of said service, the method comprising the steps of: a. monitoring successive values of the server operation parameter as a function of time, b. from such values, b1. evaluating a first condition, which involves whether the server operation parameter passes a first threshold value in a first direction, and b2. evaluating a second condition, which involves whether the server operation parameter passes a second threshold value in a second direction, wherein the second condition includes determining that the second direction is opposite to the first direction, and extends from the first threshold value to the second threshold value, c. starting rejection of input requests, upon verification of a third condition, wherein the third condition comprises (i) determining a predetermined grace period subsequent to verification of the first condition has elapsed, and (ii) determining the second condition has not been verified during said grace period; and d. terminating rejection of input requests upon verification of a fourth condition, related to the verification of said second condition.
