Patent number: 12206589Abstract: A communication control apparatus configured to control bands for flows monitors the amount of communication of each of the flows input to the communication line in a predetermined monitoring period. When a sum of the amounts of communication of the flows acquired by the monitoring exceeds a predetermined threshold, the communication control apparatus restricts the communication bands for the top N flows in the descending order of the amount of communication input to the communication line, according to the amounts of communication of the flows. In contrast, the communication control apparatus does not restrict the communication bands for flows lower than the top N flows.Type: GrantFiled: August 14, 2019Date of Patent: January 21, 2025Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Hiroki Iwahashi, Kaori Kurita, Koji Sugisono, Hidetaka Nishihara, Kazuhiro Matsuo

Patent number: 11888743Abstract: Prefix entries are efficiently stored at a networking device for performance of a longest prefix match against the stored entries. A prefix entry generally refers to a data entry which maps a particular prefix to one or more actions to be performed by a networking device with respect to network packets or other data structures associated with a network packet that matches the particular prefix. In the context of a router networking device handling a data packet, the one or more actions may include, for example, forwarding a received network packet to a particular “next hop” networking device in order to progress the network packet towards its final destination, applying firewall rule(s), manipulating the packet, and so forth. To reduce a total amount of space occupied by a prefix tree in storage, each of the nodes of a prefix tree may be configured to store only an incremental portion of a prefix relative to its parent node.Type: GrantFiled: December 3, 2019Date of Patent: January 30, 2024Assignee: Innovium, Inc.Inventors: Puneet Agarwal, Rupa Budhia, Meg Lin

Patent number: 11728951Abstract: Channel State Information (CSI) is reported by a subscriber station to a base station. The CSI is reported periodically for at least two physical uplink control channels (PUCCH). In case of a collision between a report for a first PUCCH and a report for the second PUCCH, each of the report types is partitioned into one of a number of classes, which include: a first class for rank indicator related report types and wideband (WB) W1 report types; a second class for WB report types or WB channel quality indicator report types; and a third class for subband related report types or W1 report types. A priority rule assigns a priority to each of the classes. The CSI feedback reports are transmitted according to the priority rule such that the report type included in a higher class is transmitted and the report type included in the lower class are dropped.Type: GrantFiled: November 11, 2019Date of Patent: August 15, 2023Assignee: Samsung Electronics Co., Ltd.Inventors: Lingjia Liu, Young-Han Nam, Jianzhong Zhang

Patent number: 11533259Abstract: The present disclosure provides an approach for scaling the number of VNFs in a data center without scaling the number of control sessions between VNFs and a data center gateway. The approach includes opening a session between a VNF and a route server, rather than between the VNF and the gateway, when the VNF needs to send its connectivity information to the gateway. The VNF sends its connectivity information to the route server, and the route server forwards the connectivity information to the gateway. The gateway receives connectivity information of a plurality of VNFs in the data center from the route server rather than from each of the VNFs individually. The connectivity information is then used to send packets, by the gateway to a VNF, for processing. The packets are sent using three layers of networking: an underlay physical network, an overlay logical network, and a second overlay logical network.Type: GrantFiled: July 24, 2019Date of Patent: December 20, 2022Assignee: VMware, Inc.Inventors: Sami Boutros, Jerome Catrouillet, Sri Mohana Singamsetty
