Embodiments described herein relate to the adaptation of a real-time Web communication transmission profile, particularly the adaptation of throughput such as the video throughput of the real-time Web communication. A method is described for adapting a real-time Web communication transmission profile, including changing a transmission profile parameter of a real-time Web communication device on the basis of bandwidth-related data recovered during a real-time Web communication time period. Thus, the transmission profile can be adapted to the bandwidth of the real-time Web communication in progress, allowing a user to enjoy the best quality when the bandwidth allows and, conversely, to limit transmission errors when the bandwidth does not allow high throughput.

This application describes transmission control methods and devices. One method comprises: sending, by a first device to a second device, first control signaling that instructs the second communications device to send a first group of data packets, the first control signaling comprises a first packet sequence number, a first packet sequence number range, and a first transmission time interval, the first group of data packets correspond to sequence numbers within the first packet sequence number range starting from the first packet sequence number, and the first transmission time interval indicates a time interval for sending data packets of the first group of data packets; and receiving, by the first device from the second device, at least one data packet in the first group of data packets.

The disclosure describes example techniques for determining a data rate at which destination blocks are to receive data unit on a communication mesh. The destination block may determine the data rate at which the destination block is to receive data unit and broadcast information indicative of the data rate on a congestion mesh. The congestion mesh may be configured to route the broadcasted information in a manner that accounts for the relative positions of the circuit blocks in the congestion mesh.

Described embodiments provide systems and methods for adapting/negotiating media information. A first device may determine a channel quality of a wireless channel in an unlicensed spectrum between the first device and a first tethered device. The first device may determine a first bit rate supportable on the wireless channel according to the channel quality. The first device may send, to the second device, an offer message with an offered bit rate comprising a lower of the first bit rate or a second bit rate supportable by a connection between the first device and the second device at least partially across a licensed spectrum. The first device may receive, from the second device, a reply message with a reply bit rate that is less than or equal to the offered bit rate, to apply to wireless communication across at least the first tethered device, the first device and the second device.

A first node and a second node transmit packets to a third node via a switch. The packets are buffered in a Tx buffer in the switch and then transmitted to the third node. When the third node detects a sign of congestion at the Tx buffer based on the reception frequency of the packets, it is recognized, from transmitter addresses included in the received packets, that the nodes transmitting the packets to the third node are the first node and the second node, and a control packet for a transmission stop request is transmitted to the first node and the second node. On receiving the control packet for a transmission stop request, the first node stops transmission of only packets addressed to the third node. On receiving the control packet for a transmission stop request, the second node stops transmission of only packets addressed to the third node.

A node (110) of a communication network forwards a first data packet (301) from a server (150) to a client (10). Further, the node detects a congestion affecting the first data packet (301). Further, the node (110) generates at least one second data packet (306) addressed to the server (150). The at least one second data packet (306) indicates the detected congestion and comprises verification information enabling the server (150) to verify that the indicated congestion relates to the first data packet (301).

Systems and methods of communicating in a network use rate limiting. Rate limiting units (either receive side or transmit side) can perform rate limiting in response to a) a maximum number of bytes that can be solicited over a first period of time is exceeded, b) a maximum number of bytes that are outstanding over a second period of time is exceeded; or c) a maximum number of commands that are outstanding over a period of time is exceeded as part of CMD_RXRL. The CMD_RXRL, can have three components (a) max bytes, b) outstanding bytes, c) outstanding commands. TXRL, contains the component of max bytes or maximum number of bytes that can be transmitted over a third period of time to match the speed of a receive link, or any node or link through the network/fabric.
