摘要： [Problem] To provide a means that enables consistent high performance data transfer between different data communication devices via a network, with no compounding of network congestion. [Solution] In the present invention, a receiving side data communication device (12) calculates, at prescribed times, an actual measured RTT, which is the time required for data to travel to a transmission side data communication device (11) and back, a data transfer rate (R) for the data transfer, and a data loss ratio (L), which is the ratio of the number of packets not received by the receiving side data communication device (12) to the number of packets sent from the transmission side data communication device (11). The receiving side data communication device (12) uses the most recent data transfer rate (R) and the data loss ratio (L) to calculate a transfer score (S) according to a prescribed calculation formula, and increases or decreases the reference RTT in accordance with the change in the transfer score (S). The receiving side data communication device (12) gives instructions to the transmission side data communication device (11) to increase or decrease the data transfer rate in accordance with the results of a comparison of the reference RTT and the actual measured RTT.

摘要： A method of maintaining data packet forwarding information in a first network node of a wireless mesh communications network having a plurality of network nodes interconnected by wireless communications links is disclosed. The method includes receiving respective activity indicators for neighbour network nodes connected with the first network node by respective wireless communications links, and determining respective link indicators for the outgoing wireless communications links of the first network node, each such link indicator being indicative of a data packet transmission characteristic for the link concerned. The method further includes, for each of the outgoing communications links of the first network node, combining the link indicator associated with that outgoing wireless communications link with the activity indicator relating to the neighbour network node connected with the first network node via that outgoing wireless communications link, thereby to generate a routing value for the outgoing wireless communications link for the destination network node. A selected next communications link for the destination network node is determined from the generated routing values; and is then stored as forwarding information relating to the selected next communications link for the destination network node concerned.

The method may additionally include determining an interval time defining an interval between the first time and the second time. The method may also comprise causing an indication of the interval time to be sent to the sending apparatus. Corresponding apparatuses are also provided.

摘要： A system, which uses the internet to deliver time sensitive information, includes an overlay node, having a plurality of overlay nodes, which are used to deliver the time sensitive information. To better characterize the connection between a sending node and a receiving node, the sending node periodically requests each overlay node in the path between the sending node and the receiving node to force a retransmission of a packet, while also forwarding that same packet to the next overlay node. In this way, the delay associated with each link in the path can be quantified and recorded by the receiving node. Based on the observed transmission delays, the receiving node may determine an optimal buffer time. This buffer time is the amount of buffering performed at the receiving node prior to outputting the time sensitive information.

摘要： A method of compensating for jitter in a packet stream is described. The method comprises placing undecoded frames extracted from packets in the packet stream into a jitter buffer while decoding frames from the jitter buffer and placing the decoded frames into a sample buffer at a rate determined using an average playout delay. The average playout delay is the running average of the playout delay calculated for each packet as each packet becomes available. The playout delay for each packet is the sum of a sample buffer delay and a jitter buffer delay. As each packet is received, the average playout delay is adjusted based on a comparison of the playout delay associated with the received packet to the current average playout delay.

摘要： The invention concerns a receiver comprising: a jitter buffer (208) configured to store packets of a media stream to provide a jitter compensated flow of packets, wherein each packet includes a timestamp; and a processing device (210) configured: to determine a timestamp of each packet k to be fetched from the jitter buffer based on the receiver time (R k ) and on a jitter buffer delay J of the jitter buffer; and to set the value of J based on a predicted reception time of each packet k determined based on the timestamp of each packet k.
