Abstract: According to an example aspect of the present invention, there is provided apparatus comprising at least one processing core, at least one memory including computer program code, the at least one memory and the computer program code being configured to, with the at least one processing core, cause the apparatus at least to store group definition information, receive plural reports from a set of distributed-computing entities each report comprising performance information and a transaction identifier, form a group of at least a proper subset of the plural reports based on their respective transaction identifiers and the group definition information, and obtain an aggregate performance report using both the performance information in each one of the reports in the group, and a performance metric of the group.

Abstract: A service function chain including service functions which process user plane packets is controlled by providing (S21) a shared context comprising rules and policies for processing the user plane packets, the shared context being shared between the service functions of the service function chain, reading (S22) the shared context, and adjusting (S23) traffic flow across the service function chain based on the rules and policies associated with the read shared context.

Abstract: The invention introduces a method to inform/configure a peer-to-peer application environment such that an application can find good alternatives for peer selection and data exchange taking the network configuration conditions including caching strategies and deployment into account. In use, a mobile operator stores a tracker file that is used to provide information of likely locations of a data file sought by an end user. The mobile operator provides instructions to a mobile communication device of the end user regarding the location of a tracker file that is available for use by said mobile communication device. In this way, the mobile operator controls the peer-to-peer environment available to the end user.

Abstract: In a method and apparatus for a data communication system data sessions provided in response to service requests are monitored. Based on the monitoring information regarding data communicated from at least one data source during the monitored sessions is determined. Statistical information is collected based on the determination(s). Performance of at least one operation is caused based on the statistical information.

Abstract: A method for caching data is disclosed, in which a network apparatus (401) partitions (600) the data into chunks to be stored in at least one priority cache and in at least one secondary cache. In response to receiving (602), in the network apparatus (401) a content request message (601) related to a user terminal (403), the apparatus checks (602) whether prioritized chunks of the requested content are available in a priority cache, the apparatus transmits (603) the prioritized chunks of the content from the priority cache to the user terminal (403). The apparatus (401) also retrieves non-prioritized chunks of the content to the priority cache from a secondary cache, wherein the retrieved non-prioritized chunks are transmitted (605) to the user terminal (403).
