<p>The present invention relates to the technical field of communications. Provided are a cached data processing method and device, solving the problem of reduced buffer zone performance because a page not accessed for a long time is not deleted in time. The method comprises: determining the elimination weight cardinal number of the page; each time after a page has operations performed, adding the elimination weight cardinal number of the page to a first preset value; if the elimination weight value has a preset upper limit value, then at each elimination scan, subtracting a second preset value from the elimination weight value not satisfying a preset condition; if the elimination weight value has no preset upper limit value, then at each elimination scan, calculating in a such manner that the elimination weight value not satisfying the preset condition is inversely proportional to the storage time of the corresponding page in the buffer zone, obtaining the elimination weight value of the current page; and deleting from the buffer zone the page corresponding to the elimination weight value satisfying the preset condition. Thus the present invention is applicable to page replacement in the buffer zone.</p> |
