A network adapter includes a receive (RX) pipeline, a transmit (TX) pipeline, hardware-implemented congestion-control circuitry, and a congestion-control processor. The RX pipeline is configured to receive packets from a network and process the received packets. The TX pipeline is configured to transmit packets to the network. The hardware-implemented congestion-control circuitry is configured to receive, from the TX pipeline and from the RX pipeline, Congestion-Control (CC) events derived from at least some of the packets transmitted to the network and from at least some of the packets received from the network, and to pre-process the CC events. The congestion-control processor is configured to receive the pre-processed CC events from the congestion-control circuitry, and to throttle a transmission rate of the packets transmitted to the network by the TX pipeline responsively to the pre-processed CC events.

A method is provided that includes setting, by a controller, a first bit-rate level for a next video segment, and comparing a fill level of a playback buffer to a first threshold. If the fill level of the playback buffer satisfies the first threshold, the first bit-rate level for the next video segment is replaced by setting a second bit-rate level for the next video. A first request is issued to a server for the next video segment encoded at the first bit-rate level or, if the fill level of the playback buffer satisfies the first threshold, encoded at the second bit-rate level and downloading of the requested next video segment and storing the requested video segment in the playback buffer. A decoder decodes the next video segment from the playback buffer for playback on a display device after the next video segment has been downloaded and stored in the playback buffer.

Embodiments of the present application relate to the technical field of computers, and provides a method and an apparatus for node speed limiting, an electronic device and a storage medium. The method comprises: receiving bandwidth data reported by a node under a target domain name, wherein the bandwidth data comprises the number of node connections and a node bandwidth, and the number of node connections is the number of connected devices in the node; and calculating a bandwidth quota for the node based on the bandwidth data and a quota upper limit for the target domain name.

A network element includes a transmit-queue for transmitting packets from at least two sources, each source having a predefined priority level, to a headroom buffer in a peer network element. Flow-control circuitry receives from the peer network element signaling that indicates a number of credits for transmitting packets to the peer network element, manages a current number of credits available for transmission from the transmit-queue, responsive to the signaling, selects a threshold priority based on the current number of credits for the transmit-queue; and transmits packets associated with data sources of the transmit-queue that are higher in priority than the threshold priority, and refrain from transmitting other packets associated with the transmit-queue.

A network adapter includes a receive (Rx) pipeline, a transmit (Tx) pipeline and congestion management circuitry. The Rx pipeline is configured to receive packets sent over a network by a peer network adapter, and to process the received packets. The Tx pipeline is configured to transmit packets to the peer network adapter over the network. The congestion management circuitry is configured to receive, from the Tx pipeline and from the Rx pipeline, Congestion-Control (CC) events derived from at least some of the packets exchanged with the peer network adapter, to exchange user-programmable congestion control packets with the peer network adapter, and to mitigate a congestion affecting one or more of the packets responsively to the CC events and the user-programmable congestion control packets.

A data transmission method and related apparatuses are disclosed. A sanding node transmits a plurality of data packets to a receiving node at an initial transmission rate. Each data packet carries a random sequence number and a rolling sequence number. The random sequence number identifies a data part of the data packet, and the rolling sequence number indicates a transmission sequence of the data packet. The sending node receives a packet loss feedback from the receiving node. The packet loss feedback is generated after the receiving node detects a packet loss event according to rolling sequence numbers of received data packets. The sending node determines a random sequence number of a lost data packet based on the received packet loss feedback. The sending node transmits a replacement data packet to the receiving node. The replacement data packet carries a different rolling sequence number.

Systems and methods are provided for operating a media transmission network. The system includes at least one destination device for receiving a plurality of media streams from a plurality of source devices. The system further includes a controller that is configured to, for each media stream of the plurality of media streams: determine a media property adjustment for the media stream based at least on the media stream; identify a source device from the plurality of source devices associated with generating the media stream; determine at least one device setting for the identified source device to apply the media property adjustment to the media stream; generate a control packet for configuring the identified source device based on the at least one device setting, the control packet including the at least one device setting; and transmit the control packet to the identified source device.
