Abstract: Systems, methods, and computer-readable for cognitive sensor fusion management include obtaining one or more data streams from one or more sensors. Learning algorithms are used for determining whether a combination of the one or more data streams includes sufficient information for achieving a desired outcome, based on context, business verticals, or other considerations. One or more modifications are determined to at least the one or more data streams or one or more sensors based on whether the combination of the one or more data streams includes sufficient information for achieving the desired outcome. In a closed-loop system, feedback from implementing the one or more modifications can be used to update the desired outcome.

Abstract: Disclosed herein are systems, methods, and computer-readable media for upgrading vSmart controllers. In one aspect, a method includes an edge router receiving a notification from a vSmart controller that an upgrade to the controller will occur. The notification can be dynamically triggered by a centralized network management system. In some embodiments, the vSmart controller can run as a virtual machine (VM) and maintains a control plane connection with one or more edge routers in an overlay network. In response to the notification, a length of time of an expiry timer in which the edge router attempts to connect to the vSmart controller can be increased, and the edge router can connect to the vSmart controller once the increased length of time has passed.

Abstract: Methods and systems for encoding multi-level pulse amplitude modulated signals using integrated optoelectronics are disclosed and may include generating a multi-level, amplitude-modulated optical signal utilizing an optical modulator driven by first and second electrical input signals, where the optical modulator may configure levels in the multi-level amplitude modulated optical signal, drivers are coupled to the optical modulator; and the first and second electrical input signals may be synchronized before being communicated to the drivers. The optical modulator may include optical modulator elements coupled in series and configured into groups. The number of optical modular elements and groups may configure the number of levels in the multi-level amplitude modulated optical signal. Unit drivers may be coupled to each of the groups. The electrical input signals may be synchronized before communicating them to the unit drivers utilizing flip-flops. Phase addition may be synchronized utilizing one or more electrical delay lines.

Abstract: Opportunistic power grant, and specifically to providing opportunistic power grants to Access Points (APs) by an Automated Frequency Coordination (AFC) may be provided. An Access Point may be operating in a low power mode. The AP may connect to a STA and send a token to the STA, wherein the token includes a request for a STA location. The AP may receive the STA location in response. The AP may send the token and the STA location to an AFC. The AP may then receive instructions to operate in a standard power mode from the AFC. The AP may change operation to the standard power mode in response.

Abstract: Improving transmitter Effective Isotropic Radiated Power (EIRP) may be provided. Improving EIRP may include sending a trigger frame to a client and receiving an uplink transmission from the client in response. A client Transmission (TX) power and a Received Signal Strength Indication (RSSI) associated with the client may be determined using the uplink transmission. Next, a client location may be determined. A pathloss associated with the client may be determined using the client location and the uplink transmission. A directional gain may then be determined using the client TX power, the pathloss, and the RSSI. An array gain is determined based on the directional gain. An Access Point (AP) TX power is adjusted based on the array gain.

Abstract: Network energy efficiency and green power selection may be optimized by employing graph-oriented service chains configured to share sustainability attributes and metadata augmentation. More specifically, network Service Function Chain (SFC) creation can include a set of power and energy-specific and sustainable attributes. In general, the goal of SFC is to enable the creation of a service path that matches the specific needs of an application or service. SFCs are composed of a sequence of network functions, such as firewalls, load balancers, intrusion detection systems, and other services. Each network function performs a specific task on the network traffic, and the packets are passed from one function to the next until they reach their destination. Overall, SFCs are a powerful tool for managing complex network environments, enabling network administrators to deploy and manage network services more efficiently and effectively.
