  • Patent number: 10833889
    Abstract: A method for monitoring control systems, a device for monitoring control systems and a corresponding computer program product, wherein the control system has at least one communication network and at least two communication end points connected to the communication network, which communication end points exchange data via the communication network, wherein the data exchanged between the communication end points is acquired and after comparing the currently acquired data with previously acquired data, an alert is raised when new data is acquired. As a result, a monitoring is provided which recognizes errors particularly quickly and reliably in the context of communication in control systems, in particular in industrial control systems. These errors may subsequently be coupled with a quality management to determine whether quality losses correlate with such recognized errors.

  • Patent number: 10834679
    Abstract: Channel state information reference signal transmission can be used to estimate channel state information. Although resources needed for channel state information reference signals can be small, when multiple bandwidths are deployed within the same orthogonal frequency division multiplexing bandwidth, estimating the channel state information can comprise a channel state information reference signal resource grid for every bandwidth. Therefore, time-frequency resources for channel state information reference signals can be high and occupy a lot of bandwidth, thereby reducing the number of resources for data transmission. Therefore, a non-orthogonal design for channel state information reference signals for a 5G air interface can mitigate bandwidth loss in a 5G network.

  • Patent number: 10798000
    Abstract: A method and apparatus of a device that determines a match for a compressed address using an exact match table of a network element is described. In an exemplary embodiment, the network element receives a data packet that has a destination address. The network element further compresses the destination address to give a compressed address.

  • Patent number: 10785161
    Abstract: A method is provided by which a network adapter device receives a packet sent over a network from a peer, the packet including an enqueue timestamp indicating when the packet has been enqueued at the network adapter device. The network adapter device parses a header of the packet to detect whether the header includes bits indicating that the peer device is experiencing congestion, and obtains packet metadata of the packet and the enqueue timestamp of the packet. The network adapter device compares the packet metadata with information in a flow table to identify an entry in the flow table corresponding to a flow to which the packet metadata matches. The network adapter device sets a timer associated with the flow, the timer for use in scheduling transmission of a next packet provided by the host to be sent to the peer.
