One or more network traffic scheduling parameters are adjusted in response to the estimated effective network speed, such as a maximum currently usable network speed that is lower than a maximum possible speed of the network. The maximum currently usable network speed of the network connection is periodically increased if the monitored latency is in a normal state and the maximum currently usable network speed is lower than the maximum possible speed of the network.Type: GrantFiled: July 8, 2021Date of Patent: January 23, 2024Assignee: Avast Software s.r.o.Inventor: Michal Vaner

Patent number: 11863999Abstract: Apparatus and methods for operating wireless devices using unlicensed frequency ranges with minimal transmission interruptions. In one embodiment, the apparatus and methods provide a mechanism for redirecting idle or inactive wireless devices to different frequencies in response to interference detection such as by 5 GHz-band radar. In one variant, the present disclosure provides methods and apparatus for allowing user device (UEs) using 5G NR-U spectrum to continue to operate upon radar detection by successfully switching the UEs to one or more frequencies that are free of radar operation. In one variant, a gNB controlling the UEs informs the AMF (access and mobility function) of a radar detection event, and the AMF initiates a paging towards idle UEs in order to allow the gNB to move the UEs to a frequency without radar operations. In another variant, a gNB switches its UEs to a different frequency without relying on the AMF.Type: GrantFiled: April 25, 2022Date of Patent: January 2, 2024Assignee: CHARTER COMMUNICATIONS OPERATING, LLCInventors: Maulik Vaidya, Ahmad Reza Hedayat, Amitav Mukherjee

Patent number: 11863412Abstract: A packet information analysis method and a network traffic monitoring device are disclosed. The method includes the following. Network flow data including a plurality of network packets is obtained. An index parameter is generated according to packet information (e.g., header information) of the first network packet among the network flow. A target mapping model is determined from a plurality of candidate mapping models according to the index parameter. The index parameter is between a first sampling point and a second sampling point of the target mapping model. An interpolation mapping value is obtained according to the index parameter, the first sampling point, the second sampling point, and the target mapping model. An evaluation value is obtained according to the interpolation mapping value. The evaluation value reflects a distribution status of a monitoring item in the network traffic flows.Type: GrantFiled: May 20, 2022Date of Patent: January 2, 2024Assignee: Chung Yuan Christian UniversityInventors: Yu-Kuen Lai, Cheng-Lin Tsai, Kai-Po Chang

Patent number: 11863675Abstract: Datacenters or other large-scale distributed computing systems can provide computing resources such as processing power and data storage as computing services accessible to tenants via a computer network. A tenant, such as a corporation, school, or organization, can have multiple users or groups of users with corresponding websites. To facilitate ready access, data relevant to a user, group, or website of a tenant can be stored in a dedicated network location sometimes referred to as a shard. A shard can be a physical and/or logical storage location that contains emails, chats, instant messages, documents, photos, videos, or other types of content items with which the user, group, or website can interact.Type: GrantFiled: April 6, 2022Date of Patent: January 2, 2024Assignee: MICROSOFT TECHNOLOGY LICENSING, LLCInventors: Ariane Belle Tsai, Aigerim Shintemirova, Nicole Isis Cranon, Annalilia Horstmann Cavazos, Serguei Vasilyevich Martchenko, Yuva Priya Arunkumar, Andrew Kovalenko

Patent number: 11855899Abstract: A network device for use with a client device and a cable modem termination system (“CMTS”), the client device being configured to run applications requiring data traffic of a first and second quality of service (“QoS”). The CMTS is configured to provide a first service flow and a second service flow to the network device. The network device provides a local area network (“LAN”) for connection to the client device and a network address translation (“NAT”). The NAT is configured to map the network device IP address to the client device IP address; divide the source ports into a first range and a low latency range; assign the respective data traffic of the applications to at least one port within the first range and to at least one port within the low latency range; and modify the low latency range of source ports based on a change in data traffic.Type: GrantFiled: February 17, 2023Date of Patent: December 26, 2023Assignee: ARRIS ENTERPRISES LLCInventors: Sabarinathan Nagarajan, Lakshmi Arunkumar, Ian G.
