摘要： For providing an efficient network use and resource allocation within the network a method for operating a network is provided, wherein user network traffic is controlled by an operator, comprising the following steps: a) monitoring user network traffic data on a per user basis, b) using said network traffic data in a learning process for providing a prediction of user network traffic on a per user basis, and c) controlling user network traffic under consideration of said prediction, including allocating network resources under consideration of said prediction to one or more users, preferably for providing a definable Quality of Service, QoS, per at least one of said one or more users and/or per at least one other user. Further, a corresponding network is claimed.

摘要： For improving network efficiency and performance by simple means a method for operating a network is provided, wherein an occupation level of at least one switch queue of at least one network switch is estimated, the method comprising the following steps: Providing or collecting data regarding an association between at least one path delay and a corresponding switch queue occupation level of the at least one switch queue; feeding the data to a machine learning model associated with the at least one switch queue; training the machine learning model on the basis of the at least one path delay or the data to predict a switch queue occupation level of the at least one switch queue; and using an information resulting from the trained machine learning model or using the predicted switch queue occupation level for making a real-time traffic steering decision for load balancing between network paths. Further, a corresponding network is provided.

摘要： A method for monitoring of a physical environment's proneness to infectious disease transmission, the method comprising: - in a training phase: obtaining unlabeled sensor data from sensors of the physical environment in order to provide a set of sensor features; generating, in particular by applying situation labeling functions, a labeling matrix that is fed to a generative model, wherein said generative model feeds a discriminative classifier model with probabilistic labels for the sensor features, wherein the probabilistic labels of the generative model are used for training the discriminative classifier model; determining, in particular by a feature selection optimizer entity, a subset of the sensor features based on an optimization procedure; and - in an operational phase: using, by the discriminative classifier model, the subset of sensor features for detecting predefined situations, which make the physical environment prone to infectious disease transmission. Furthermore, a corresponding system monitoring of a physical environment's proneness to infectious disease transmission is disclosed.

摘要： A method for supporting memory deduplication for unikernel images, the method comprising: aligning, by a memory aligner entity, memory pages of unikernel images such that a consistent memory alignment is generated across the unikernel images; generating, by a memory deduplication identifier entity, a unique page identifier for the memory pages of the unikernel images; matching, by the memory deduplication identifier entity, page identifiers of memory pages for a unikernel image, which is to be loaded into a physical memory, with page identifiers of memory pages that have already been loaded into the physical memory and providing matching information about the matching to a page merger entity; performing, by the page merger entity, page merging based on the matching information provided by the memory deduplication identifier entity. Furthermore, a corresponding system is disclosed.

摘要： A method for service function chaining in a network, comprises defining, for a flow of network packets sent from a source node (4) to a destination node, a chain of selected network service functions (1) to be traversed by the flow, wherein each of the selected network service functions (1) is attached or connected to a programmable switch (2) capable of operating as a packet forwarding element, generating a chain establishment packet that contains network identifier information about the selected network service functions (1) and that is configured as a regular network packet to be delivered to the destination node along a network path that includes the programmable switches (2) to which the selected network service functions (1) are attached or connected, wherein each of the programmable switches (2), upon receipt of the chain establishment packet and based on the network identifier information about the selected network service functions (1) contained in the chain establishment packet, performs installation of packet forwarding rules for the flow together with network address and port translation operations, and selects, on behalf of the respective attached or connected network service function (1), socket parameters to be used by the network service function (1) for processing the flow. Furthermore, the present invention relates to a network switch and a network addressable apparatus hosting a network service function.
