Abstract: A faulty link detection method includes receiving statistical data that is reported by all nodes every preset quantity of packets that carry a program clock reference value. All the nodes collect statistical data starting from a unified program clock reference value. The quantity of packets lost between an upstream node and a downstream node among all the nodes is acquired according to the statistical data. A faulty link is determined according to the quantity of packets lost between the upstream node and the downstream node.

Abstract: The present invention discloses a method, an apparatus, and a system for implementing video quality assessment. When video quality is assessed, a proportion of a damaged data caused by packet loss in a video frame in which the damaged data is located is considered, and other factors are also considered, such as a position of the damaged data in the video frame and impact of a scene in which the video frame is located on the video frame or a video frame located after the video frame. Therefore, accuracy of quality assessment is higher.

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.

Abstract translation: 缓存服务器的服务方法涉及通信领域，并且可以减少上游网络的带宽消耗并减轻网络压力。 该方法包括：接收由多个用户设备发送的第一请求信息，其中第一请求信息指示多个用户设备单独要求的数据和分别需要的数据的请求点; 如果确定在多个用户设备中由至少两个用户设备发送的第一请求信息中指示相同的数据，并且相同的数据没有被缓存在高速缓存服务器中，则从落入预设的请求点中选择一个请求点 窗口; 以及向源服务器发送第二请求信息，其中第二请求信息指示未被缓存的数据和所选择的请求点。
