Abstract:
1. A network packet loss processing method, comprising: comparing, at a comparing unit of a network packet loss processing apparatus, a value of a current congestion window of a network with a buffer threshold when a packet loss event is detected, wherein the buffer threshold is used to indicate a data bearing capability of the entire network, wherein the data bearing capability is obtained by adding a data bearing capability of a link in the network and a data bearing capability of a buffer of a node in the network; if the value of the current congestion window is smaller than the buffer threshold, not performing backoff processing on the current congestion window; and if the value of the current congestion window is greater than or equal to the buffer threshold, performing backoff processing on the current congestion window; wherein the buffer threshold is obtained through the following formula, and the formula is: wherein: m-cwnd indicates the buffer threshold, and its value is an integer that is greater than 0; indicates a data bearing capability of a link in the network, wherein BWE indicates a transmission bandwidth of a link from a sending end to a receiving end in network transmission and its value is an integer that is greater than 0, RTTmin indicates a minimum round trip delay detected by the sending end and its value is an integer that is greater than 0, and MSS indicates a maximum segment size used in network transmission and its value is an integer that is greater than 0; and indicates a data bearing capability of a buffer of a node in the network, wherein BWE indicates the transmission bandwidth of the link from the sending end to the receiving end in the network transmission and its value is an integer that is greater than 0, ALPHA indicates an adaptive parameter of the data bearing capability of the buffer of the node in the network and its value is in direct proportion to the minimum round trip delay detected by the sending end and a network packet loss ratio, and MSS indicates the maximum segment size used in the network transmission and its value is an integer that is greater than 0.
