Examples described herein relate to a router interface device. In some examples, the router includes an interface and circuitry. In some examples, the circuitry is to: proactively drop a packet and send a negative acknowledgement (NACK) message to a sender based on lack of buffer space for a response associated with the packet and sent from a downstream network interface device that received the packet and also based on one or more of: congestion at a downstream switch or congestion at an endpoint receiver.

Examples described herein relate to a router. In some examples, the router includes an interface and circuitry coupled to the interface. In some examples, the circuitry is to determine whether an incoming packet is to reach a faulty link based on a fault location received in a received negative acknowledgment (NACK) message and based on a determination that the incoming packet is to reach the faulty link, drop the packet one or multiple hops before reaching the faulty link.

Technologies for endpoint congestion avoidance are disclosed. In order to avoid congestion caused by a network fabric that can transport data to a compute device faster than the compute device can store the data in a particular type of memory, the compute device may in the illustrative embodiment determine a suitable data transfer rate and communicate an indication of the data transfer rate to the remote compute device which is sending the data. The remote compute device may then send the data at the indicated data transfer rate, thus avoiding congestion.

Systems and methods allow playback of a media stream received via a network. The media stream is received and stored in a buffer prior to playback. Responsive to receiving the user command to change the content of the media stream, the buffer is flushed prior to receiving the changed content in the media stream.

A method of precoding the power of a channel of a ground terminal in communication with a satellite. The ground terminal is subject to limitations in terrestrial mobile network rates and other congestion conditions. An actual signal-to-interference-plus-noise ratio is calculated and adjusted according to a desired signal-to-interference-plus-noise ratio for a predetermined time epoch. The actual signal-to-interference-plus-noise ratio is adjusted while considering the competing requirements of both: the energy of the difference between the successive actual/desired signal-to-interference-plus-noise ratio levels and the energy of the control sequences. The actual signal-to-interference-plus-noise ratio is autonomously converged with the desired with the signal-to-interference-plus-noise ratio, subject to the limitations in terrestrial mobile network rates and other congestion conditions, by dynamically minimizing covariance error and predicting gain for the epoch.

In some examples, the circuitry is to: based on detection of a drop of a packet of a flow: drop subsequently received packets of the flow and based on receipt of a packet associated with the dropped packet of the flow, forward the received packet and subsequent received packets of the flow.
