摘要： A method, a content management module (110), a computer program (503) and a carrier (505) for managing content in a content distribution network (100) are disclosed. The content distribution network (100) comprises a plurality of caches (140), a content serving node (120), a client device (130). The content management module (110) obtains an indication that the content is to be delivered, in an upcoming time period, to the client device (130). The content management module (110) obtains a transport capability parameter relating to transport capability, in a past time period, from the plurality of caches (140) to an output means (131). The content management module (110) predicts, for said each cache, a respective predicted transport capability based on the respective set of parameters. The content management module (110) segments the content into a plurality of segments based on the respective predicted transport capability. The content management module (110) selects at least one respective cache (141-144) based on the respective predicted transport capabilities. The content management module (110) provides a respective command to the content serving node (120). The respective command instructs the content serving node (120) to feed said each segment to the selected at least one respective cache.

摘要： A data collection coordination function, DCCF, network node receives (1a) a request for data from a data consumer, determines (2) a data source for the requested data, verifies (3a, 3b) with a network node that the data consumer and the DCCF are authorized by the data source, receives (3b) a message container for the data consumer from the network node, the message container for the data consumer including a data encryption key KE and a data integrity key Ki, and receives (3b) a message container for the data source from the network node, the message container for the data source including the data encryption key KE and the data integrity key Ki. The DCCF network node transmits (4a) the message container for the data consumer to the data consumer and transmits (5) the message container for the data source to the data source.

摘要： Mechanisms for performance degradation reporting in a microwave system, which comprises a point-to-point wireless microwave link, are provided. A method is performed by a controller entity. The method comprises obtaining classified microwave link data. The classified microwave link data represents microwave link data of the point-to-point wireless microwave link as classified to operating conditions in a set of operating conditions. The method comprises detecting performance degradation affecting data throughput in the microwave system by analysing performance data of the point-to-point wireless microwave link. The method comprises determining, by using the performance data and cause of the performance degradation that attention from an operator entity in the microwave system is required. The cause is defined by the microwave link data as classified to the operating conditions. The method comprises providing an indication to the operator entity only when attention from the operator entity is required. The indication is an indication of the performance degradation and the cause of the performance degradation.

摘要： An apparatus in a mobile communication network combines information from monitoring IP flows carrying latency sensitive content passing the apparatus and information about the application behavior and target Quality of Experience (QoE) or target connectivity characteristics such as Quality of Service (QoS) from the application to provide ongoing predictions of QoE/QoS. In some cases, the apparatus exploits a probe on a device to generate traffic for learning flow characteristics not obtained from monitoring application IP flows in the network. Embodiments disclosed herein can be used to predict quality metrics for many applications where jitter/latency is a factor affecting perceived quality, such as QoE for a human consumer or QoS for machine type communications. The embodiments are applicable to the analysis of traffic carrying conversational speech.

摘要： A server (600), a client device (602) and methods therein, for handling cached content resources. When the client device (602) sends a download request (6:3) in a downloading session, the server (600) identifies (6:4) at least one content resource deemed to be potentially needed later in the downloading session. The server (600) then sends a cache map to the client device (602) in a response to the download request. The cache map comprises a pre-fetch indication indicating that the identified at least one content resource should be pre-fetched by the client device (602) from a cache (604) containing the identified at least one content resource. Thereby, the client device is able to pre-fetch (6:8) the content resources before the performance of communication may become reduced so that communication with the cache (604) is difficult or even impossible, e.g. due to deteriorated radio conditions or congestion in the communication network.
