Apparatuses, methods, and systems are disclosed for determining data available for transmission. One method includes associating a packet data convergence protocol entity with a first radio link control entity and a second radio link control entity belonging to two different cell groups. The method includes determining an amount of data available for transmission, the amount of data available for transmission including packet data convergence protocol data and radio link control data pending for initial transmission in the first radio link control entity and the second radio link control entity. The method includes comparing the amount of data available for transmission with a threshold. The method includes submitting the packet data convergence protocol data to a first radio link control entity in response to the amount of data available for transmission being below the threshold.

A computing device, a method, and a system to enforce concurrency limits within a network fabric. The computing device includes a memory device; and a network interface controller coupled to the memory device. The network interface controller includes circuitry to communicate with a plurality of target computing devices in a network fabric. The circuitry is configured to generate packets for transmission to respective ones of a plurality of target nodes. For each packet addressed to its corresponding target node, the circuitry is to determine whether transmitting the packet would violate the target node's concurrency limit. If transmitting the packet would not violate the target node's concurrency limit, the circuitry is to transmit the packet to the target node. However, if transmitting the packet would violate the target node's concurrency limit, the circuitry would store the packet in a retransmit buffer of the computing device, where the retransmit buffer is to further store already transmitted packets flagged for retransmission. The circuitry would then transmit the packet from the retransmit buffer when transmitting the packet from the retransmit buffer would not violate the target node's concurrency limit.

Disclosed are methods lossless traffic forwarding using distributed delay offset matching. The lossless traffic forwarding method includes calculating a delay offset between a first forwarding path between a transmitting node and a receiving node and a second forwarding path between the transmitting node and the receiving node, and controlling a buffer resource by an extent of the delay offset to delay packets to be forwarded on the first forwarding path.

A method and system may allow for adjusting network latency experienced by a user. A first computing device may send a request to adjust the latency experienced by a terminal associated with a user. The request may be received at a second computing device which may identify a buffer size for to the terminal associated with the user. A new buffer size may be determined and adjusted for the identified buffer based on the received request.

A network adapter includes a host interface, a network interface, a memory and packet processing circuitry. The memory holds a shared buffer and multiple queues allocated to the multiple host processors. The packet processing circuitry is configured to receive from the network interface data packets destined to the host processors, to store payloads of at least some of the data packets in the shared buffer, to distribute headers of at least some of the data packets to the queues, to serve the data packets to the host processors by applying scheduling among the queues, to detect congestion in the data packets destined to a given host processor among the host processors, and, in response to the detected congestion, to mitigate the congestion in the data packets destined to the given host processor, while retaining uninterrupted processing of the data packets destined to the other host processors.

This application is directed to a camera system having one or more processors, memory having a limited capacity, a camera element and a microphone. The camera system captures video and audio data in real-time via the camera element and the microphone, respectively. While capturing the video and audio data in real-time, the captured video and audio data are stored in the memory having the limited capacity, and sent to a remote server system via the communication interface for storage by the remote server system. The camera system determines that a portion of the video and audio data was not available at the remote server system. In accordance with a determination that at least some of the portion is still available in the memory having the limited capacity, the camera system resends the at least some of the portion from the memory to the remote server system via the communication interface.

A network interface device, said network interface device has a data transmission path configured to receive data for transmission. The data for transmission is to be sent over a network by the network interface device. A monitor is configured to monitor the data transmission path to determine if an underrun condition is associated with the data transmission path. If so, an indication is included in the transmitted data packet.

A method performed by a radio access network node of a wireless communication network, for handling a wireless communication device capable of alternating between an idle state and an active state. The method comprises receiving packets related to a communication between the wireless communication device and an external node, and determining whether the packets are directed only from the external node towards the wireless communication device. If so, the node refrains from sending a paging notification to the device for a first time period including a first in time occurring active state of the device after the determination, but if not, the node sends the paging notification to the device at the first in time occurring active state.

A buffer module includes N queues configured to buffer M data streams, where N is less than M. A counting module includes M counters, the M counters are in a one-to-one correspondence with the M data streams, and the M counters are configured to count buffer quantities for the M data streams in the N queues. The control module is configured to, when a count value on a first counter exceeds a corresponding threshold, discard a to-be-enqueued data packet of a data stream corresponding to the first counter, or control the sending module to send pause indication information to an upper-level control module.

Embodiments of the invention disclose a data transmission method, a device, and a computer storage medium to perform data transmission. A congestion status of a transmission port is obtained by a first device. The transmission port is a communications port used by the first device when a second device transmits data to the first device. The congestion status is used to indicate whether data congestion occurs on the transmission port. Indication information is sent to the second device when a mode switching condition is met. The indication information is used to instruct the second device to switch a transmission mode used when the second device transmits the data, so that the second device transmits the data to the first device in a switched transmission mode, and the mode switching condition is associated with the congestion status of the transmission port.
