The invention relates to a method of controlling packets in a data packet network, the method comprising the steps of: a source node sending a first set of packets to a receiver node over the data packet network via an intermediate node, wherein the first set of packets are marked as being of a class of service preventing them from being forwarded to the receiver node if a packet queue exists at an intermediate node; the source node receiving an acknowledgement of a received packet of the first set of packets from the receiver node; and the source node sending a second set of packets to the receiver node over the data packet network.

A congestion control method includes obtaining, by a first network node, a current queue buffer status of each of N second network nodes, combining, by the first network node, current queue buffer statuses of the N second network nodes and a current queue buffer status of the first network node into a state vector, updating, by the first network node, the current queue buffer status of the first network node according to the state vector and a coupling vector; and repeating all the above steps till an absolute value of a difference between each of the queue buffer statuses of the N second network nodes and the queue buffer status of the first network node is less than or equal to a preset threshold.

A method of adaptive transmission time interval (TTI) tuning based on TCP information is proposed. First, a procedure for TCP information delivery between eNB and TCP sender/TCP receiver is disclosed. The TCP information comprises TCP status, TCP congestion window (CWND) size, TCP round trip delay, TCP SS threshold, TCP index, and TCP event indication. Second, various methods for eNB to configure TTI with UE TCP information and/or buffer information are disclosed. A first method is saturation detection which includes buffer status based saturation detection and CWND based saturation detection. A second method is Greedy Buffer Clearing. A third method is TCP state based TTI selection method.

A method of delivering media content over a network, the media content including a plurality of temporal segments, wherein each temporal segment comprises a plurality of data packets, the method including: selecting an initial size of a first congestion window; delivering the plurality of data packets of a first segment using the first congestion window, the initial size of the first congestion window being used to control the size of the first congestion window for the duration of the first segment delivery; measuring the packet loss during the delivery of the first segment; determining an initial size of a second congestion window in dependence on the measured packet loss for the first segment; and delivering a second segment using the second congestion window, the initial size of the second congestion window being used to control the size of the second congestion window for the duration of the second segment delivery.

A packet transmission method and related apparatus are disclosed. A transmit end retransmits a first packet to a receive end and decreases a congestion window and a slow start threshold upon determining that the first packet has been lost. The receive end sends an ACK in response to the retransmitted first packet to the transmit end on receipt of the retransmitted first packet for the first time, where the ACK contains a proactively constructed DSACK option for informing the transmit end that the first packet has been received repeatedly. The transmit end therefore compensates the congestion window and/or the slow start threshold.

In a computer-implemented method for reducing delay of bursty data transmission in a network employing a congestion control protocol, data is accessed that is to be periodically transmitted over a network employing a congestion control protocol. The data is to be periodically transmitted with a high burst rate followed by an idle period. The congestion control protocol progressively increases a data transmission rate during a data transmission rate increase period invoked immediately following a predetermined idle period. Prior to transmitting the data, priming data is transmitted during at least a portion of the idle period until the congestion control protocol progressively increases the data transmission rate to a desired transmission rate. The data is transmitted at the desired transmission rate.

The present invention discloses a transmission control method, apparatus and system, so as to effectively utilize network link resources. The method of the present invention includes: acquiring link status information about a network; determining recommended values of TCP transmission parameters according to the link status information; and performing TCP transmission according to the determined recommended values of the parameters. The present invention can enable TCP transmission status to reflect network congestion status more real, prevent a congestion misjudgment from occurring, and improve a utilization ratio of link resources in a network.

This disclosure relates to a system and method for modifying selected network congestion control parameters using mobile system information. The congestion control modification improves network performance between a remote server on the Internet and a mobile device. As the proliferation of data-rich content and increasingly more capable mobile devices has continued, mobile consumers increasingly demand better network performance from their mobile devices and mobile infrastructure. This disclosure provides systems and methods for using mobile system information related to Quality of Service guarantees to modify network congestion control.

The present disclosure generally relates to the field of data delivery. More specifically, the present disclosure relates to a technique of supporting delivery of data packets using Transmission Control Protocol (TCP) in a wireless communication network. A method embodiment comprises identifying (S202), by a base station of the wireless communication network, an imminent end of a slow start phase of TCP congestion control.
