Self-adaptive energy-saving control method, device and system based on traffic predication

The invention discloses a self-adaptive energy-saving control method, device and system based on traffic predication. The method includes the steps that various indexes relevant to traffic of a server cluster in all historical time periods are collected; historical traffic of the server cluster in all the historical time periods is calculated by utilizing the various indexes relevant to the traffic in all the historical time periods; according to the historical traffic in all the historical time periods, traffic of the server cluster in the next time period is predicated; by utilizing correction factors corresponding to date classification which the next time period belongs to, the traffic in the next time period is corrected; if the largest historical traffic is larger than or equal to traffic of the next time period after being corrected, the number and/or the work states of servers operating in the service cluster are adjusted according to the corrected traffic in the next time period; when the work states
