Disclosed herein are systems and methods for audio synchronization for hearing devices. An audio packet is received from a host device at a first hearing device configured to be worn in a first ear of a wearer, the audio packet compatible with a wireless low energy digital communication protocol, and the audio packet is received from the host device at a second hearing device configured to be worn in a second ear of the wearer. Upon one or more programmable conditions, a synchronization packet is sent from the first hearing device to the second hearing device. An acknowledgment packet is sent from the second hearing device to the first hearing device upon receipt of the synchronization packet, and a first transducer at the first hearing device and a second transducer at the second hearing device are unmuted to deliver synchronized audio to the first ear and to the second ear.

A system, apparatus, method, and non-transitory computer readable medium for implementing a fault-tolerant multi-NRF network topology may include a network repository function (NRF) device including: at least one processor configured to execute computer readable instructions to cause the NRF device to, broadcast a NRF query to a NRF cluster of a core network, the NRF cluster including a plurality of NRF devices located in a public land mobile network (PLMN); receive NRF query responses from each NRF device of the NRF cluster, the NRF query responses including network configuration information of each NRF device; determine a status of each NRF device based on the network configuration information; determine a list of network function (NF) devices registered with the NRF cluster; receive a NF query request from a first NF device; and transmit a NF query response to the first NF device.

Provided is a roadside unit including: communication circuitry, which, in operation, receives data transmitted from an on-board unit and transfers the data to a server; and control circuitry, which, in operation, suspends, in a case where the communication circuitry has received an upload resume request for the data from the on-board unit while the data is being transferred to the server, transfer of the upload resume request to the server.

Systems and methods for reducing bandwidth loss in IPv6 packet switching networks. A network appliance is configured to sample IPv6 packets and mirror sampled packets to a working memory or memory structure, such as a queue. A transport layer payload is extracted from each sampled packet and a transport layer checksum validation operation is performed. Upon detecting an error, the network appliance updates a dropped packet rate or other metric.

Methods, apparatus, and computer-accessible storage media for providing redundant storage gateways. A client may create a storage gateway group and add storage gateways to the group. The client may assign one or more volumes on a remote data store to each the storage gateways in the group. Volume data for each storage gateway in the group may be replicated to at least one other storage gateway in the group. If one of the gateways in the group becomes unavailable, one or more other gateways in the group may take over volumes previously assigned to the unavailable gateway, using the replicated data in the group to seamlessly resume gateway operations for the respective volumes. Client processes that previously communicated with the unavailable gateway may be manually or automatically directed to the gateway(s) that are taking over the unavailable gateway's volumes.

The present disclosure provides methods for detecting faults in a distributed computing network system. The method includes receiving, from a management services, authority information identifying peer computing devices of a distributed computing network system. For each respective peer computing device, a first message comprising a first instance of a dataset and a second message comprising a second instance of the dataset are received. Where the first peer computing device and the second peer computing device have authority over the data set, it is determined whether the first instance of the dataset matches the second instance of the dataset. Where the first instance of the dataset does not match the second instance of the dataset, a fault message is sent to the management services indicating that a fault has been detected at the first peer computing device.

A method, a system, and a computer program product for determining whether signals are received by one or more devices in a virtual meeting. The method includes transmitting a data stream received from one or more host computing devices to one or more user computing devices in a plurality of user computing devices. The host and user computing devices are communicatively coupled using a real-time online connection. A first hash in a plurality of hashes is generated by the server using a portion of the data stream and stored in a memory location. The first hash is compared to a second hash received from the user computing devices. The second hash is generated by the user computing devices upon receipt of the transmitted data stream. Based on the comparison, a status of the real-time online connection between the host computing devices and the user computing devices is determined.
