Abstract: Methods and systems are described herein for detecting deviations from an expected power profile of a device. The method comprises: retrieving a manufacturer usage description (MUD) associated with the device. The MUD includes a power profile associated with the device. An expected power consumption parameter can be determined from the power profile. The method may further comprise monitoring an actual power consumption parameter of the device and comparing the expected power consumption parameter to the actual power consumption parameter. The method may further comprise determining a deviation between the power consumption parameter and the expected power consumption indicated in the power profile, and outputting a notification when the deviation is equal to or greater than a threshold value.

Abstract: Granular guard interval tuning may be provided. A delay profile for a plurality of sub-bands in a serving channel may be created. Then delay spread information from at least one calibration helper device for the plurality of sub-bands in the serving channel may be received. Next, a delay spread matrix based on the delay profile, the delay spread information, and a location of the calibration helper devices may be created. The delay spread matrix may then be used to determine optimal Guard Intervals (GIs).

Abstract: In one embodiment, a device registers with a controller for a mesh of overhead access points. The device receives, from the controller, a communication schedule for the device. The device generates a message to be sent to the mesh of overhead access points. The device transmits, according to the communication schedule, the message as a beam cone directed substantially upward relative to the device towards the mesh of overhead access points. The message is received and relayed by one or more particular access points in the mesh without the device previously performing a wireless association exchange with those one or more particular access points.

Abstract: Described herein are devices, systems, methods, and processes for managing power congestion in multi-path routing systems. Indications may be similar to the ECN, and may be used in network headers, including headers for IPv6, SRv6, NSH, or other tunneling protocols. The indications, namely EOPN, PTE, and ECMP-exclude, can provide a mechanism for managing network power consumption and controlling ECMP routing based on flow priority and characteristics. The power budget can be dynamically adjusted based on the current power source mix, which may help to achieve sustainability goals. Hashing optimizations and signaling can be utilized to manage network power congestion and bandwidth-normalized power efficiency availability. A process may be implemented to ensure there is sufficient capacity to serve the expected traffic for different next-hop paths. Additionally, the ECN can be used to quickly react to congestion, bring capacity back online, and maintain optimal network performance, even in the absence of congestion.

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.

Abstract: Broadcast operations by a selected subset of Access Points (APs) may be provided. A first plurality of APs to perform broadcast may be selected from a plurality of APs. Next, a plurality of client devices may be moved from a second plurality of APs to the first plurality of APs during a broadcast period. Then, the plurality of client devices may be moved to the second plurality of APs from the first plurality of APs after the broadcast period.

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. These devices, systems, methods, and processes enable efficient power management in network nodes while maintaining optimal network performance and contributing to sustainability goals.

Abstract: Personal network Software Defined-Wide Area Networks (SD-WANs) with attested permissions may be provided. A first one of a plurality Personal Area Network (PAN) devices in a PAN may seed a routing table entry for at least one application that the first one of the plurality PAN devices supports. The routing table entry may include at least one characteristic associated with an egress link between the first one of the plurality PAN devices and a device outside of the PAN. The routing table entry may be exchanged among the plurality of PAN devices in the PAN. Then data may be routed, based on the exchanged routing table entry, in the PAN through the first one of the plurality PAN devices through the egress link to the device outside of the PAN.

Abstract: In one embodiment, a method comprises: identifying, by a low power and lossy network (LLN) device in a low power and lossy network, a minimum distance value and a distance limit value for limiting multicast propagation, initiated at the LLN device, of a multicast data message in the LLN; and multicast transmitting, by the LLN device, the multicast data message with a current distance field specifying the minimum distance value and a distance limit field specifying the distance limit value, the multicast transmitting causing a receiving LLN device having a corresponding rank in the LLN to respond to the multicast data message by: (1) determining an updated distance based on adding to the current distance field a rank difference between the receiving LLN device and the LLN device, and (2) selectively retransmitting the multicast data message if the updated distance is less than the distance limit value.
