The methods, devices, and systems discussed herein describe four different mechanisms (e.g., solutions) to assist a leader of a group of wireless communication devices in deciding when to switch between groupcast and unicast transmissions. In the first solution, the group leader may decide to initiate groupcast or unicast without considering the design of the Access Stratum (AS) layer link management. In the second solution, the group leader can determine whether to initiate unicast transmission based, at least partially, on feedback messages received from one or more other members of the group. In the third solution, the group leader has the option to simultaneously transmit groupcast and unicast transmissions towards the same user equipment devices (UEs). In the fourth solution, the group leader indicates to the groupcast-receiving UEs that the transmission is about to be switched from groupcast to unicast.

An information transmission apparatus includes a generating unit and a receiving unit. The generating unit generates a second instruction part when a first instruction part is selected. The first instruction part gives an instruction to perform a first transmission process of transmitting information to multiple first transmission destinations. The second instruction part gives an instruction to perform a second transmission process of transmitting the information to at least one second transmission destination among the first transmission destinations. The at least one second transmission destination is a transmission destination to which the information fails to be transmitted. The receiving unit receives change of a second transmission setting for the second transmission process. The second transmission setting is associated with the second instruction part and includes destination information of the at least one second transmission destination.

In one embodiment, a first computer networking device executes an election algorithm to determine whether at least the first computer networking device or a second computer networking device is responsible for forwarding, to at least one receiving device, communications addressed to a specified group of computing devices. The first computer networking device may further store first data indicating that the first computer networking device is responsible for forwarding the communications. However, in response to the first computer networking device determining that it is no longer receiving the communications, it may store second data indicating that the first computer networking device is no longer responsible for forwarding the communications and may send, to the second computer networking device, third data indicating that the first computer networking device is not receiving the communications.

The subject disclosure relates to systems and methods for improving multicast traffic flows in a computer network. In some aspects, a method of the technology includes steps for receiving multicast traffic statistics from each of a plurality of switches in a computer network, aggregating the multicast traffic statistics into a time-series database, and identifying a low-performing multicast flow based on the time-series database. In some aspects, the method can include steps for automatically reconfiguring the computer network to improve the low-performing multicast flow. Systems and machine readable media are also provided.

A system and method to provide automatic status notifications of screensharing status to meeting participant devices participating in a screensharing session in a virtual meeting via a virtual meeting server, to, after an activation of the screen sharing session, determine if content frames for the screensharing session sent from a presenter device have reached other receiving meeting participant devices, determine if the received content frames meet predetermined threshold requirements, determine if an acknowledgment response has been sent to the virtual meeting server from a receiving device confirming receipt of the content frames, and generate a status notification to indicate on a user interface of the presenter device whether the content frames have been received by the receiving devices and meet the predetermined threshold requirements or fail to meet the predetermined threshold requirements.

A method may be provided to operate an access node of a wireless communication network. A first frame may be provided including a first header and a first data block with first data for a first wireless terminal and a second wireless terminal. The header may include a first control field indicating a first idle period resource and a second control field indicating a second idle period resource, and the first and second idle period resources may be different. Transmission of the first frame to the first and second wireless terminals may be initiated. Responsive to receiving a notification message using the first idle period resource, a second frame may be provided including a second header and a second data block with second data for the second wireless terminal. Transmission of the second frame to the second wireless terminal may be initiated while deferring transmission to the second wireless terminal.

A hybrid cloud-based media production system includes a facility extension platform having a hardware processor and a memory storing a software code. The hardware processor executes the software code to identify multicast production media flow(s) for processing in a cloud-based virtual production environment, to identify cloud-based resource(s) for processing one or more cloud production media flow(s) corresponding to the multicast production media flow(s), in the cloud-based virtual production environment, and to coordinate provisioning of the cloud-based virtual production environment with the identified cloud-based resource(s). The hardware processor also executes the software code to align, using a cloud permissible timing protocol, the timing of the cloud production media flow(s) in the cloud-based virtual production environment, and to process the cloud production media flow(s) in the cloud-based virtual production environment using the identified cloud-based resource(s).

A wireless audio output device including a first audio output unit and a second audio output unit is provided. The wireless audio output device establishes a wireless link with an audio source, which outputs a first original audio data and a second original audio data. The first and the second audio output units simultaneously output and play the first and the second original audio data. When the first audio output unit successfully receives the first original audio data but the second audio output unit fails to receive the second original audio data, the first audio output unit drops the received first original audio data, and the first and the second audio output units generate a first concealment audio data and a second concealment audio data, respectively, by using a PLC algorithm and play the first concealment audio data and the second concealment audio data, respectively.

According to some embodiments, a system for reducing bandwidth usage is disclosed. The system comprises a computer server that receives a request to initiate a multicast communication over a computer network and a computer readable medium comprising instructions that perform a method when executed by the centralized computer server. The method comprises initiating a multicast communication and assigning a unique identifier to the multicast communication. A set of messages associated with the unique identifier is received. If it is determined that a number of messages is greater than a pre-determined number of messages, determining a location of each of the users and grouping the users into a first group and into a second group where the first group are all located within a pre-defined radius based on a first determined location and the second group are all located within a pre-defined radius based on a second determined location.
