  • Patent number: 12659766
    Abstract: Systems and techniques for dynamically optimizing a wireless network topology to minimize energy consumption while preserving user quality of experience (QoE) are described. An example technique includes determining a set of applications that have a target service level agreement (SLA). Network traffic is monitored from the set of applications being executed by one or more client STAs within a network. A topology of the network is dynamically adapted to reduce an amount of energy consumption in the network while maintaining a threshold amount of the network traffic that satisfies the target SLA, based on monitoring the network traffic.

  • Patent number: 12659227
    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.

  • Patent number: 12628185
    Abstract: Techniques for managing communications between access points (APs) and stations (STAs) are described herein. In one embodiment, an AP broadcasts a trigger message to a plurality of STAs, the trigger message including a matrix defining a plurality of resource units (RUs) that the plurality of STAs are assigned to transmit or receive data, and a fragment flag. The presence of the fragment flag, within the scheduling matrix, informs the AP that the data transmission that the fragment flag is appended to is a partial transmission that will be completed in a subsequent transmission opportunity.

  • Patent number: 12627749
    Abstract: Systems, methods and computer-readable storage media are provided for encoding, within the SRH-6LoRH field within a data packet, an IPv6 address that can be used to decompress the SCHC information in the data packet. A rule is generated that indicates that the first network address in the SRH-6LoRH field of the data packet is usable to decompress the SCHC information from the data packet as opposed to the compression residue. When the data packet is received at the destination node, the destination node, through a SCHC decompressor, uses the first network address in the SRH-6LoRH field according to the rule to decompress the SCHC information.

  • Publication number: 20260128916
    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.

  • Publication number: 20260121944
    Abstract: A cross-domain approach to optimize Wireless Fidelity (WiFi) device roaming in a fabric-based network may be provided. A first Access Point (AP) may determine a current location of a first user device connected to the first AP of a fabric-based network. The first AP may be attached to a first Fabric Edge (FE). The first AP may receive an indication of movement of the first user device from the current location. The first AP may predict a next AP where the first user device is most likely to roam to from the first AP based on the current location and a trajectory of the movement from the current location. The next AP may be attached to a second FE of the fabric-based network. The first AP may trigger pre-provisioning of resources at the second FE to create a secondary route for the first user device through the second FE.
