The method includes that: a transmission side transmits a detection indication to a receiving side, the detection indication being used to indicate the receiving side to feed back a receiving state of multiple Acknowledged Mode Data (AMD) Protocol Data Units (PDU) sent by the transmission side; the transmission side receives a state report sent by the receiving side, the state report being used to indicate a receiving state of at least one AMD PDU in the multiple AMD PDUs; and if a Sequence Number (SN) of a first AMD PDU of the at least one AMD PDU is equal to a first value, the transmission side stops transmitting the detection indication for the multiple AMD PDUs to the receiving side, the first value being less than or equal to a maximum SN in the SNs of the multiple AMD PDUs. The method and device of the embodiments of the present application are advantageous in reducing unnecessary overhead.Type: GrantFiled: March 23, 2018Date of Patent: September 14, 2021Assignee: GUANGDONG OPPO MOBILE TELECOMMUNICATIONS CORP., LTD.Inventor: Cong Shi

Patent number: 11122067Abstract: Methods, non-transitory computer readable media, anomaly detection apparatuses, and network traffic management systems that generate, based on the application of one or more models and for a first flow associated with a received first set of network traffic, one or more likelihood scores and at least one flow score based on the likelihood scores. One or more of the one or more models are associated with one or more browsing patterns for a web application to which the first set of network traffic is directed. A determination is made when the flow score exceeds a threshold. A mitigation action is initiated, based on a stored policy, with respect to the first set of network traffic, when the determining indicates that the flow score exceeds the established threshold.Type: GrantFiled: August 7, 2019Date of Patent: September 14, 2021Assignee: F5 NETWORKS, INC.Inventors: Shlomo Yona, Ron Talmor, Itsik Mantin, Yaniv Shemesh

Patent number: 11122064Abstract: In some examples, a system identifies, for a given authentication event between a plurality of devices in a network, a context comprising a set of authentication events that are temporally related to the given authentication event. The set of authentication events occur at the devices. A classifier is applied on a collection of features associated with the set of authentication events, the collection of features comprising a number of machines or a number of users associated with the set of authentication events. The system determines, based on an output of the classifier, whether the given authentication event is an unauthorized authentication event.Type: GrantFiled: April 23, 2018Date of Patent: September 14, 2021Assignee: MICRO FOCUS LLCInventors: Pratyusa K. Manadhata, Mijung Kim

Patent number: 11101884Abstract: Systems and methods for displaying a localization of one or more anomalies in a fiber optic network are provided. In one implementation, a system includes a processing device and a memory device. The memory device is configured to store an anomaly localization module having logic instructions, which, when executed, cause the processing device to display, on a Graphical User Interface (GUI), Network Elements (NEs) and physical fiber plant links of a fiber optic network on a generalized geographical map. Responsive to a user selection, the logic instructions are further configured to cause the processing device to display, on the GUI, a physical fiber plant map based on obtained geographical coordinates of components associated with the fiber optic network.Type: GrantFiled: March 24, 2020Date of Patent: August 24, 2021Assignee: Ciena CorporationInventors: Christiane Louise Campbell, Tommaso D'Ippolito, Blair Moxon, Gerard L.

Patent number: 11102837Abstract: A radio terminal (3) can perform carrier aggregation using a first cell (10) of a first radio station (1) and a second cell (20) of a second radio station (2). The first radio station (1) performs, with the radio terminal (3), radio resource control for the first cell (10) and the second cell (20) in order to perform the carrier aggregation. At least one of the second radio station (2) and the radio terminal (3) is configured to transmit, to the first radio station (10), information about a problem occurring in a radio link in the second cell (20) between the second radio station (20) and the radio terminal (30) while the carrier aggregation of the first cell (10) and the second cell (20) is being performed.Type: GrantFiled: October 22, 2019Date of Patent: August 24, 2021Assignee: NEC CORPORATIONInventors: Hisashi Futaki, Hiroaki Aminaka
