Patent number: 11010322Abstract: A network on a chip (NOC) peripheral interface (NPI) includes an NPI root, a plurality of switches coupled to the NPI root, and a plurality of NPI protocol blocks coupled to the plurality of switches. The NPI root, the plurality of switches, and the plurality of NPI protocol blocks are configured to route signals received from a master to a plurality of circuit blocks. A non-service command is routed to an intended circuit block of the plurality of circuit blocks. A switch of the plurality of switches or an NPI protocol block of the plurality of NPI protocol blocks generate a response message for a service command query with the destination address associated with the intended circuit block that is received from the master instead of routing the service command query to the intended circuit block.Type: GrantFiled: June 21, 2019Date of Patent: May 18, 2021Assignee: XILINX, INC.Inventor: Abbas Morshed

Patent number: 11003488Abstract: A memory-fabric-based processor context switching system includes server devices coupled to a memory fabric. A first processing system in a first server device receives a request to move a process it is executing and, in response, copies first processing system context values to its first local memory system in the first server device, and generates a first data mover instruction that causes a first data mover device in the first server device to transmit the first processing system context values from the first local memory system to the memory fabric. A second processing system in a second server device generates a second data mover instruction that causes a second data mover device in the second server device to retrieve the first processing system context values from the memory fabric and provide the first processing system context values in a second local memory system included in the second server device.Type: GrantFiled: May 3, 2019Date of Patent: May 11, 2021Assignee: Dell Products L.P.Inventors: Shyamkumar T.

Patent number: 11006288Abstract: An automated highly efficient “design-test-optimize” recursive loop method for experimentally optimizing embedding networks of active RF networks especially subject to wideband modulated signals, whereby the results of a matching network design are fed into the active load pull system, which synthesizes the response of the specific network design iteration and tests the transistor in real time under the emulated load conditions of the network. The weighed difference between expected and test results are used in an error function and the “design-test” loop is repeated until the error is minimized. The capacity of passive and active modulated tuners and network analysis software tools are jointly used, sharing calculated and measured data. The result of the automated optimization procedure ends into a compromise, which, if acceptable, can be processed into manufacturing with realistically expectable results.Type: GrantFiled: March 13, 2019Date of Patent: May 11, 2021Inventor: Christos Tsironis

Patent number: 11005969Abstract: A method and system for debugging and attending to a problem in a message queuing system in a computer network. Information from the message queuing system is periodically gathered. The information includes current message queuing configuration data, current message queuing usage values and current server usage values. A current message queuing system configuration is periodically analyzed by comparing the information with historical data. Suggestions of different configurations for the current message queuing system are prioritized based upon criticality levels of the suggested different configurations. The current message queuing system configuration is updated from a prioritized list of the suggested different configurations with a highest criticality level at a top of the list. The suggested configuration with the highest criticality level is applied.Type: GrantFiled: January 15, 2020Date of Patent: May 11, 2021Assignee: International Business Machines CorporationInventors: Rudranil Das Gupta, Erik Houlberg, Jorgen B.

Patent number: 10999295Abstract: A traffic-monitoring system that monitors encrypted traffic exchanged between IP addresses used by devices and a network, and further receives the user-action details that are passed over the network. By correlating between the times at which the encrypted traffic is exchanged and the times at which the user-action details are received, the system associates the user-action details with the IP addresses. In particular, for each action specified in the user-action details, the system identifies one or more IP addresses that may be the source of the action. Based on the IP addresses, the system may identify one or more users who may have performed the action. The system may correlate between the respective action-times of the encrypted actions and the respective approximate action-times of the indicated actions. The system may hypothesize that the indicated action may correspond to one of the encrypted actions having these action-times.Type: GrantFiled: March 19, 2020Date of Patent: May 4, 2021Assignee: VERINT SYSTEMS LTD.Inventors: Offri Gil, Omer Ziv, Yuval Altman, Yaron Gvili, Hodaya Shabtay, Omri David, Yitshak Yishay

Patent number: 10999625Abstract: The present disclosure relates to a method and device for reporting the quality of a mobile streaming service. A terminal device receiving a mobile streaming service through at least one communication network measures the quality of the streaming service, generates, on the basis of the measurement result, a mobile service quality indicator for monitoring QoS or QoE, and reports the generated mobile service quality indicator in real time through an MQI message, an NAM feedback message, or the like, thereby enabling network conditions to be effectively monitored even in a mobile streaming environment.Type: GrantFiled: December 17, 2018Date of Patent: May 4, 2021Assignee: SK TELECOM CO., LTD.Inventor: Jongmin Lee

Patent number: 10993141Abstract: A method and apparatus are disclosed. In an example from the perspective of a first device, the first device is configured with a second set of slot offsets by a network. The first device receives, from the network, a second Downlink Control Information (DCI) scheduling a sidelink resource. The first device performs sidelink transmission, to a second device, on the sidelink resource. The first device monitors and/or receives a sidelink hybrid automatic repeat request-acknowledgement (SL HARQ-ACK) feedback from the second device in a fourth slot. The SL HARQ-ACK feedback is associated with the sidelink transmission. The first device derives, based on the fourth slot and a second slot offset value indicated by the second DCI, a third slot for transmitting a SL HARQ-ACK to the network. The second set of slot offsets includes the second slot offset value. The SL HARQ-ACK is set/derived/determined based on the received SL HARQ-ACK feedback.Type: GrantFiled: February 20, 2020Date of Patent: April 27, 2021Assignee: ASUSTek Computer Inc.Inventors: Chun-Wei Huang, Ming-Che Li
