Abstract: A serving method of a cache server relates to the field of communications, and can reduce bandwidth consumption of an upstream network and alleviate network pressure. The method include: receiving first request information sent by multiple user equipments, where the first request information indicates data separately required by the multiple user equipments and request points for the data separately required; if it is determined that same data is indicated in the first request information sent by at least two user equipments among the multiple user equipments and the same data has not been cached in the cache server, selecting one request point from request points falling within a preset window; and sending second request information to a source server, where the second request information indicates the uncached data and the selected request point.
