Abstract: A data transmission method implemented by a network device, where the data transmission method includes receiving a first data packet sent by a transmit end, buffering the first data packet to a low-priority queue when the first data packet is sent by the transmit end during a first round-trip time (RTT) of a data transmission phase between the transmit end and a receive end, receiving a second data packet from the transmit end, buffering the second data packet to a high-priority queue when the second data packet is not sent by the transmit end during the first RTT, and forwarding the second data packet in the high-priority queue before the first data packet in the low-priority queue.

Abstract: Techniques are described for buffering data traffic destined for a mobile device when a data path to a base station for the mobile device is unavailable. For example, a network device comprises: a control unit comprising processing circuitry, wherein the control unit is configured to allocate, in response to determining that a data path from the network device to the base station for a mobile device is unavailable, a hardware queue of a packet processor of the network device to the data path; and a forwarding component with access to the hardware queue, wherein the forwarding component is configured to store data traffic for the mobile device to the allocated hardware queue, wherein the control unit is configured to, in response determining that the data path is available, configure the forwarding component to output the data traffic from the allocated hardware queue to the base station along the data path.

Abstract: Methods and apparatus for efficient data transfer within a user space network stack. Unlike prior art monolithic networking stacks, the exemplary networking stack architecture described hereinafter includes various components that span multiple domains (both in-kernel, and non-kernel). For example, unlike traditional “socket” based communication, disclosed embodiments can transfer data directly between the kernel and user space domains. Direct transfer reduces the per-byte and per-packet costs relative to socket based communication. A user space networking stack is disclosed that enables extensible, cross-platform-capable, user space control of the networking protocol stack functionality. The user space networking stack facilitates tighter integration between the protocol layers (including TLS) and the application or daemon. Exemplary systems can support multiple networking protocol stack instances (including an in-kernel traditional network stack).

Abstract: A packet processing device is implemented in a network that transmits priority packets and non-priority packets having a lower priority than the priority packets. The packet processing device includes: a packet storage, a gate, a controller, a detector, a generator, and a transmitter. The packet storage stores non-priority packets. The gate is provided on an output side of the packet storage. The controller controls the gate. The detector detects a transmission pattern of the priority packets. The generator generates, based on the transmission pattern of the priority packets, a gate control signal for controlling a gate of a packet processing device implemented in another node. The transmitter transmits the gate control signal to a destination of the priority packets.

Abstract: Constraint based command invocations are dynamically queued in a cloud queue such that aspects of remote user devices may be remotely controlled with reduced exposure to inconvenient remotely issued commands. By monitoring conditions that may trigger command invocations, verifying rules of associated constraints prior to queuing command invocations, evaluating parameters to prioritize command invocations in a dynamic issuing order within cloud queue, examining factors and reverifying previously verified rules when determining whether to transmit a command from an command invocation located at a transmission position of the cloud queue, systems and methods herein provide a constrained environment within which user devices may be remotely controlled relatively free from unexpected cloud caused encumbrances during inopportune moments.

Abstract: A network interface controller (NIC) capable of efficient packet forwarding is provided. The NIC can be equipped with a host interface, a packet generation logic block, and a forwarding logic block. During operation, the packet generation logic block can obtain, via the host interface, a message from the host device and for a remote device. The packet generation logic block may generate a plurality of packets for the remote device from the message. The forwarding logic block can then send a first subset of packets of the plurality of packets based on ordered delivery. If a first condition is met, the forwarding logic block can send a second subset of packets of the plurality of packets based on unordered delivery. Furthermore, if a second condition is met, the forwarding logic block can send a third subset of packets of the plurality of packets based on ordered delivery.

Abstract: The present invention relates to a wireless communication terminal and a wireless communication method for efficiently scheduling uplink multi-user transmission.
To this end, provided are a base wireless communication terminal, including: a transceiver configured to transmit and receive a wireless signal; and a processor configured to control an operation of the transceiver, wherein the processor selects an access category for transmitting a trigger frame which solicits an uplink multi-user transmission, performs a backoff procedure for transmitting the trigger frame based on the selected access category, and transmits the trigger frame when a backoff counter of the backoff procedure expires and a wireless communication method using the same.
