Embodiment 1
[0034] According to the embodiment of the present application, an embodiment of a method for determining the bandwidth transmission capability is also provided. It should be noted that the method for determining the bandwidth transmission capability proposed in the present application uses the general ICMP (Internet ControlMessage Protocol, Internet Control Message Protocol). text protocol), it only needs to implement the method of detecting the bandwidth capability on the sending end, without the mutual cooperation between the receiving end and the sending end. In addition, the method for determining the bandwidth transmission capability proposed in this application can modify the model parameters of the detection bandwidth in real time according to the transmission rate of the data sent by the sending end in real time, so that the model parameters can be adaptively adjusted according to the network environment, and then can be Accurately detect the transmission capacity of th...
Embodiment 2
[0111] According to an embodiment of the present invention, a device for determining bandwidth transmission capability for implementing the method for determining bandwidth transmission capability described above is also provided, such as Figure 10 As shown, the device includes: a first sending module 1001 and an analyzing module 1003 .
[0112] Wherein, the first sending module 1001 is configured to send the probe data packet sequence according to the time interval parameter, wherein the time interval parameter is used to represent the interval between every two adjacent probe data packets in the probe data packet sequence sent from the sender to the receiver. The sending time interval between them; the analysis module 1003 is used to perform regression analysis on the detection data packet sequence and the response data packet sequence corresponding to the detection data packet sequence, so as to determine the transmission capability of the bandwidth to be detected.

Embodiment 3
[0124] According to an embodiment of the present invention, a method for determining a bandwidth transmission capability is also provided, wherein, Figure 11 A flow chart of a method for determining bandwidth transmission capability is shown, as shown in Figure 11 As shown, the method specifically includes the following steps:
[0125] Step S1102, sending the probe data packet sequence according to the time interval parameter, wherein the time interval parameter is used to indicate the sending time interval between every two adjacent probe data packets in the probe data packet sequence sent from the sending end to the receiving end;
[0126] Step S1104, if some data packets are lost in the response data packet sequence corresponding to the probe data packet sequence and / or the order of some data packets returned from the receiving end to the sending end changes, determine that the bandwidth to be detected is greater than the remaining bandwidth of the actual bandwidth.
