Implementations set forth herein relate to management of casting requests and user inputs at a rechargeable device, which provides access to an automated assistant and is capable of rendering data that is cast from a separate device. Casting requests can be handled by the rechargeable device despite a device SoC of the rechargeable device operating in a sleep mode. Furthermore, spoken utterances provided by a user for invoking the automated assistant can also be adaptively managed by the rechargeable device in order mitigate idle power consumption by the device SoC. Such spoken utterances can be initially processed by a digital signal processor (DSP), and, based on one or more features (e.g., voice characteristic, conformity to a particular invocation phrase, etc.) of the spoken utterance, the device SoC can be initialized for an amount of time that is selected based on the features of the spoken utterance.

Adaptive management of casting requests and/or user inputs at a rechargeable device

Systems and methods of hybrid control of a computer network are provided. The system can comprise a controller and a plurality of nodes having an in-band control plane network arranged in a directed acyclic graph routing topology. A first node of the plurality of nodes can be configured to detect a link failure of a first link, the first link being controller-directed. The first node can reverse a second link to a second node from outward-directed to controller-directed such that the first node can communicate with the controller via the second link and the in-band control plane network. The first node can detect a reversal of the second link caused by the second node. The first node can determine that the in-band control plane network is partitioned. The first node can use an out-of-band control plane network to inform the controller that the in-band control plane network is partitioned.

Systems and methods for hybrid control of computer networks

A method includes executing a user equipment (UE) device in a doze mode, a peek mode, and a normal mode. The doze mode includes terminating any connections with a network, comparing a clock time with a maintenance window schedule of maintenance time windows, and executing the peek mode when the clock time is within a maintenance time window. The peek mode includes receiving a connection request from a mobility management entity (MME) system when the MME system has been notified of at least one buffered downlink packet addressed to the UE device, and executing the normal mode in response to receiving the connection request. The normal mode includes establishing a connection to the network and receiving the at least one buffered downlink packet.

Mobile device power management

Methods and systems for generating a forwarding table for a packet switch. The system includes a route manager for the packet switch, configured to identify a plurality of multi-path groups each corresponding to a respective initial set of routing entries in the forwarding table and generate, for one or more multi-path groups, at least one replacement set of routing entries with fewer routing entries than the initial set corresponding to the respective multi-path group. The route manager selects, based on a traffic reduction cost metric, one or more of the replacement sets of routing entries, each corresponding to a different respective multi-path group, and updates the forwarding table with the selected replacement sets. In some implementations, the traffic reduction cost metric includes a traffic characteristic. In some implementations, the packet switch participates in a software-defined network (SDN) and the route manager is part of an SDN controller.

Prefix-aware weighted cost multi-path group reduction

In a method of implementing a positioning system a buffer is configured to store a buffer record for each of a plurality of position fixes determined by the receiver and a database is configured to store a database record for each of the position fixes. Buffer records are accumulated, with each buffer record corresponding to one of the position fixes determined by the receiver. A first threshold position near an area in which a degradation event occurs is identified and recorded in a first database record. A second threshold position near the area is identified in a second database record. The second threshold position is indicated by one of the position fixes outside of the area and is proximate to a position at which the degradation event ends.

Aspects and implementations of the present disclosure are directed to methods and systems for a network tolerant to a network device that is temporarily absent from the control plane. In one aspect, in general, the system includes an event manager configured to send, to a controller configured to exchange control messages with a network device, a first request to temporarily withdraw the network device from control plane interactions. The event manager then triggers an event at the network device during which the network device is non-responsive to control plane interactions. After determining that the event has completed, the event manager sends the controller a second request to restore the network device. The controller is configured to request, responsive to the first request, a network application to transition to a tolerant state; and to request, responsive to the second request, the network application to transition to a sensitive state.

Systems and methods for controlling network device temporarily absent from control panel

Aspects of the present disclosure relate to detecting and repairing permanently pauses on a flow controlled fabric. In one aspect, one or more computing devices, such as a switch or a centralized controller, may detect whether a port of a network device receives one or more pause messages. The pause messages may instruct the network device to pause data transmission. Further, the one or more computing devices may determine a period of time during which the port receives the one or more pause messages and identify the port as a permanently paused port based on the determined period of time. The one or more computing devices may then reconfigure the permanently paused port to stop complying with the one or more pause messages.

Detection and repair of permanent pause on flow controlled fabric

This disclosure provides systems, methods, and apparatus for providing a network switch for implementing weighted cost multi-pathing (WCMP). In some implementations, the switch can implement equal cost multi-pathing (ECMP) using ECMP forwarding tables. The ECMP forwarding table may include more than one output port associated with a destination address of an incoming packet. The ECMP forwarding table may become undesirably large if unequal weights were assigned to the output ports. A multi-level ECMP table can be implemented that can allow assigning weights to the output ports while being relatively small. The multi-level ECMP table can include a first level where each entry includes at most a single output port. A second level can include entries having one or more output ports.

Systems and methods for implementing weighted cost multi-path using two-level equal cost multi-path tables

In a receive system, a plurality of correlators correlate a received signal with a plurality of delayed versions of a reference signal to generate a plurality of correlator outputs. A timing error detector estimates an optimal timing based on a set of correlator outputs, and determines a timing error based on (i) the estimated optimal correlation point and (ii) an existing timing, such that the timing error is hard or soft limited between two positive thresholds and two negative thresholds.

A method of testing network device connectivity in a network by a host computing device includes identifying a topology of the network, where the network includes a plurality of communication paths connecting a plurality of network devices. The method further includes developing a test procedure based on the topology and a plurality of constraints, where a first constraint in the plurality of constraints includes sending a test data stream through each communication path in the plurality of communications paths only once in each direction. The method further includes configuring the plurality of network devices to perform the test procedure, initiating the test procedure, where initiating includes sending the test data stream from the host computing device to a first network device in the plurality of network devices, and monitoring the progress of the test procedure.

Network fabric stress test

A method includes receiving samples of audio data and storing the samples of audio data in a buffer. Each of the samples of audio data includes a plurality of bits. The method also includes transmitting each of the plurality of bits, of each of the samples of audio data retrieved from the buffer, across a single-bit bus; and subsequent to transmitting each of the samples, transmitting a selected number of dummy bits across the single-bit bus. The selected number is greater than one. The method further includes analyzing activity of the buffer and, based on the activity of the buffer, dynamically adjusting the selected number. The method also includes acquiring the samples of audio data transmitted across the single-bit bus and ignoring the dummy bits. The method further includes generating analog signals in response to the samples of audio data acquired across the single-bit bus.

Buffered audio system with synchronizing bus controller

A wireless computer network includes components cooperating together to prevent access intrusions by detecting unauthorized devices connected to the network, disabling the network connections to the devices, and then physically locating the devices. The network can detect both unauthorized client stations and unauthorized edge devices such as wireless access points (APs). The network can detect intruders by monitoring information transferred over wireless channels, identifying protocol state machine violations, tracking roaming behavior of clients, and detecting network addresses being improperly used in multiple locations. Upon detecting an intruder, the network can automatically locate and shut off the physical/logical port to which the intruder is connected.
