Abstract: A first system (11) is configured to transmit an interest message, e.g. to a router (21). The interest message specifies criteria identifying data units from an area of interest, e.g. an intersection, which are to be aggregated and comprises at least one parameter specifying how the data units are requested to be aggregated. A second system (1) is configured to receive the interest message from a sender, e.g. a router (21), determine whether the system will return an aggregation of data units matching the criteria, and return a data message comprising an aggregation of data units matching the criteria to the sender (21) if the processing means have determined that the system will return an aggregation of data units matching the criteria. The data units are aggregated in the data message in dependence on how the data units were requested to be aggregated.

Abstract: One aspect of this disclosure relates a video processing device comprising a processor for processing a manifest file for video streaming for a user. The manifest file comprises at least a plurality of positions defined for a scene that are associated with pre-rendered omnidirectional or volumetric video segments stored on a server system. The manifest file may also contain a plurality of resource locators for retrieving omnidirectional or volumetric video segments from the server system. Each resource locator may be associated with a position defined for the scene. The video processing device may be configured to associate a position of the user with a first position for the scene in the manifest file to retrieve a first omnidirectional or volumetric video segment associated with the first position using a first resource locator from the manifest file.

Abstract: In a communication network, a network function may be provided for controlling Information Centric Networking (ICN) protocol-based traffic flow between a set of user equipment (UE). This network function may be an ICN application function (ICN-AF), and may obtain information indicative of whether, and optionally to which degree, a respective ICN node is publisher of content in the exchange of content between the ICN nodes. The ICN-AF may, for example via a session management function (SMF), initiate a reassignment of a PDU session of an ICN node which is presumed to be a requester of content to a data network access point which has connectivity to, or is the same as, a data network access point assigned to an ICN node which is characterized as publisher of content.

Abstract: In a communication network, a network function may be provided for controlling Information Centric Networking (ICN) protocol-based traffic flow between a set of user equipment (UE). This network function may be an ICN application function (ICN-AF), and may obtain ICN layer information from an ICN router which is indicative of a congestion state of a current PDU session of user equipment. If the congestion state indicates congestion, the ICN-AF may initiate establishment of a new PDU session for the user equipment (UE1) or initiate upgrade of a quality of service (QoS) characteristic of the current PDU session, for example using the session management function (SMF) and via the SMF's session management of PDU sessions.

Abstract: A network node (1) is configured to receive an interest message comprising a request for a data object and metadata. The metadata specifies one or more criteria for selecting a subset of a plurality of items. The network node is further configured to determine whether there is a match between the requested data object and a plurality of items (e.g. from a CS or FIB) and select a subset of the plurality of items by applying the one or more criteria if the match has been determined to exist. At least one of the criteria is a preference specified for at least one of: factual properties of the plurality of items, usage data related to the plurality of items, usage data related to the at least one communication interface, an effort to obtain data from another network node, and a position in a range specified in the interest message.

Abstract: The invention relates to a system for receiving an interest message. The system comprises at least one communication interface, at least one memory and at least one processor. The at least one processor is configured to receive an interest message on a first one of the at least one communication interface. The interest message comprises a name of a requested data object. At least one name component of the name of the requested data object comprises a range. The at least one processor is further configured to determine whether the at least one memory comprises a named data object having a name matching the name of the requested data object and to provide the named data object on the first one of the at least one communication interface if the memory comprises the named data object.

Abstract: Methods and systems for enabling streaming of segmented content from a content delivery network to an adaptive streaming client on the basis of a manifest file are described wherein the said manifest file may comprise one or more segment identifiers. The method may comprise: selecting at least one segment identifier from said manifest file, said identifier identifying a segment that has not been requested by said client; and, sending pre-announce information to said content delivery network for announcing in advance that said segment may be requested by said client, said pre-announce information comprising said at least one segment identifier, said pre-announce information being further arranged for triggering said content delivery network to ensure availability of said segment upon receiving said request.
