摘要： This application discloses a communication method and a communication apparatus. The method includes: An access network element receives first indication information from a session management function network element, and activates a congestion acquisition function of the access network element based on the first indication information, where the congestion acquisition function is for obtaining a congestion status of the access network element in a data flow transmission process of a target service. The access network element obtains the congestion status of the access network element, and sends first congestion information to a terminal device or a user plane function network element, where the first congestion information indicates the congestion status of the access network element. In this application, the access network element sends, to the user plane function network element or the terminal device, the first congestion information indicating the congestion status of the access network element. In this way, the congestion status of the access network element can be reported to a transmitter of a data flow of the target service, so that the transmitter can adjust a sending window of the data flow of the target service based on the congestion status of the access network element, thereby reducing a transmission delay of the data flow of the target service.

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.

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.
