  • Patent number: 12034707
    Abstract: Techniques for using Network Address Translation (NAT), Mobile Internet Protocol (MIP), and/or other techniques in conjunction with Domain Name System (DNS) to anonymize server-side addresses in data communications. Rather than having DNS provide a client device with an IP address of an endpoint device, such as a server, the DNS instead returns a random IP address that is mapped to the client device and the endpoint device. In this way, IP addresses of servers are obfuscated by a random IP address that cannot be used to identify the endpoint device or service. The client device may then communicate data packets to the server using the random IP address as the destination address, and a gateway that works in conjunction with DNS can convert the random IP address to the actual IP address of the server using NAT and forward the data packet onto the server.

  • Publication number: 20240201306
    Abstract: Disclosed are systems, apparatuses, methods, and computer-readable media for identifying a location of a wireless device. A method for identifying a location of a wireless device includes transmitting a request message to the wireless device for identifying a position of the wireless device; receiving a response message from the wireless device; determining first time information based on a time of flight (ToF) of the request message and the response message, wherein the ToF corresponds to a distance of the wireless device from the AP; receiving a second message from a second AP that includes second time information associated with the request message and the response message; receiving a third message from a third AP that includes third time information associated with the request message and the response message; and transmitting location configuration information to the wireless device for the wireless device to determine a position of the wireless device.

  • Publication number: 20240172298
    Abstract: In one embodiment, an access point of an overhead mesh of access points in an area selects a range of client identifiers. The access point sends, via a beam cone transmitted in a substantially downward direction towards a floor of the area, a trigger signal that includes the range of client identifiers and prompts client devices having identifiers in that range to send best effort transmissions towards the overhead mesh. The access point detects a collision between the best effort transmissions of the client devices. The access point adjusts the range of client identifiers so as to avoid future collisions between the best effort transmissions of the client devices.

  • Publication number: 20240163211
    Abstract: Disclosed herein are systems, methods, and computer-readable media for forwarding packets between parallel IPv4 networks that includes encapsulating an IP packet to include an outer header and an inner header. The IP packet is routed to a shaft spanning a subset of addresses within the source realm. Upon reaching the shaft in the source realm, a first swap of the inner header and the outer header of the IP packet is performed. The IP packet is forwarded inside the shaft from the source realm to the destination realm. Upon reaching the destination realm, a second swap of the inner header and the outer header of the IP packet is performed. The IP packet is forwarded in the destination realm to the destination node.

  • Publication number: 20240155500
    Abstract: Described herein are devices, systems, methods, and processes for managing power consumption in network nodes by dynamically disabling and reenabling features based on real-time power consumption monitoring and historical data analysis. A machine learning model is trained using historical sensor data and historical feature data to predict power consumption and derive feature-to-power association data. The power budget is determined based on sustainability goals. Real-time power consumption is monitored, and features are disabled or reenabled based on their priorities and power consumption levels to maintain the power budget. The machine learning model is validated and updated using new historical data to improve its prediction accuracy and adaptability. The feature-to-power association data is distributed to network nodes and management systems for power management purposes.

  • Publication number: 20240154826
    Abstract: Described herein are devices, systems, methods, and processes for intelligently managing power consumption in a network by allocating a power budget for packet processing. The power budget can be allocated based on criticality and/or the trust level of the flow. A network device may determine which subsets of features can be executed within the power budget for specific flows. Network devices can signal their capability to run features based on power consumption and adherence to the power budget, allowing for cooperative end-to-end power-based decision-making and policy enforcement. Network devices unable to run all features can select a subset of the features within their power budget and a viable path where other network devices can execute the missing features. Source route information can be added to indicate the path and missing features to be executed by network devices down the segment routing path.

  • Patent number: 11979366
    Abstract: Techniques for using Network Address Translation (NAT), Mobile Internet Protocol (MIP), and/or other techniques in conjunction with Domain Name System (DNS) to anonymize server-side addresses in data communications. Rather than having DNS provide a client device with an IP address of an endpoint device, such as a server, the DNS instead returns a virtual IP (VIP) address that is mapped to the client device and the endpoint device. In this way, IP addresses of servers are obfuscated by a virtual network of VIP addresses. The client device may then communicate data packets to the server using the VIP address as the destination address, and a virtual network service that works in conjunction with DNS can convert the VIP address to the actual IP address of the server using NAT and forward the data packet onto the server.

  • Patent number: 11979862
    Abstract: Providing for time sensitive networking (TSN) traffic in high density deployments is described. An access point (AP) is a high density deployment receives a message identifying another AP as a TSN neighbor and also detects a TSN device within an area covered by the APs. This arrangement may cause traffic interruptions for the TSN traffic between the TSN device and the APs. In order to prevent disruption in TSN traffic, a TSN time slot and a resource unit (RU) is determined for each of the APs, and the TSN traffic is communicated between the various devices in network according to the determined TSN time slot and RU.

  • Patent number: 11941146
    Abstract: A container includes a user program and data generated by the user program within a regulatory jurisdiction. Before the container leaves the regulatory jurisdiction, the data is validated by the jurisdiction to ensure the data complies with privacy laws of the jurisdiction. Upon ingress to a second regulatory jurisdiction, the data is signed locally to provide for confirmation that the data can leave the second regulatory jurisdiction, since it was not generated within the second jurisdiction. By allowing the user program to move from the first regulatory jurisdiction to a second regulatory jurisdiction, the disclosed embodiments overcome limitations in current solutions that restrict access to local data based on what a public application programming interface (API) can provide. By operating within the regulatory jurisdiction, albeit subject to access controls imposed by that jurisdiction, flexibility in the processing of sensitive data is improved.
