The detection device in the embodiment of the present application may be a destination device that receives a packet, or may be an intermediate forwarding device.

In the embodiment of the present application, each first packet corresponds to one piece of network state information, and three specific implementation manners are provided below.

In a first mode

When an intermediate device between a sending device and a detecting device forwards a first message, adding first information in the first message, where the first information is used to indicate network state information corresponding to the first message, for example, when the length of a forwarding queue of the intermediate device exceeds a set threshold or meets other specific conditions, adding an Explicit Congestion Notification (ECN) flag or other network state information (e.g., cache queue state information) in the first message. And the detection equipment obtains the network state information corresponding to the first message according to the first information in the first message.

Mode two

When sending a first message, a sending device adds second information to the first message, the second information being information of the sending device when the sending device sends the first message, and a detecting device can obtain third information, the third information being information of the detecting device when the detecting device receives the first message. The detection device may determine, according to the second information and the third information, network state information corresponding to the first packet.

For example, the sending device adds, to a first packet, time information of the sending device when the sending device sends the first packet, which is hereinafter referred to as first time, and the detecting device obtains, when the detecting device receives the first packet, time information of the detecting device, which is hereinafter referred to as second time. If the time between the sending device and the detection device is synchronous, the time delay of the first message transmission can be obtained according to the time difference between the second time and the first time, and the network state information of the first message can be obtained according to the time delay; if the sending device and the detecting device are not time-synchronized, the time delay change of the first message transmission can be obtained according to the time difference change between different first messages, and then the network state information is obtained, for example, the network state becomes worse when the time difference becomes larger, and the network state becomes better when the time difference becomes smaller.

Mode III

When the sending device sends the first message, fourth information is added to the first message, and the detection device can determine network state information corresponding to the first message according to the received fourth information of different first messages.

For example, the fourth information is sequence information of the first packet, and the detection device may obtain, according to the received fourth information of different first packets, a packet loss condition or a disorder condition of the first packet, so as to obtain network state information corresponding to the first packet.

In this embodiment, the detection device may determine the adjustment information of the sending device according to the network state information corresponding to the at least one first packet, and two specific implementation manners are provided below.

In a first mode

According to the statistical result, the change of the network state can be determined, and whether the sending device is adjusted or not and how to adjust the sending device can be further determined.

Mode two

And substituting the network state information of at least one first message into a specific algorithm for calculation, and determining whether to adjust the sending equipment or not and how to adjust the sending equipment according to the calculation result.

In the embodiment of the application, the detection device may adjust the sending device in units of flows, receive a flow message from the network, determine whether the flow has ended, if not, process the network status information corresponding to the message, the processing process may be to count the network status information of a plurality of messages, or to calculate by substituting the network status information into an agreed algorithm, the processing result may be whether to adjust the sending device or how to adjust the sending device, and then determine whether a condition for sending a notification message is satisfied, if so, encapsulate the processing result into the notification message, and send the notification message to the sending device.

In this embodiment, the sending device may perform adjustment in units of flows, receive the notification message from the detecting device, extract adjustment information from the notification message, determine whether the corresponding flow ends, and perform adjustment according to the adjustment information if the corresponding flow does not end, for example, adjust a sending parameter, adjust a sending mode, and adjust a sending policy.

The embodiment of the present application may perform adjustment in units of flows, where there is only one traffic path of one flow in a normal case, and there may be multiple traffic paths of one flow in a load sharing case, for example, there may be two traffic paths of one flow between the terminal device 111a and the terminal device 114b in fig. 1.

In a possible design, the adjustment may not be performed in units of flows, for example, all flows between the sending device and the detecting device may be adjusted simultaneously, or a flow that may be newly added in the future between the sending device and the detecting device may be adjusted (for example, an initial sending rate of a new traffic flow is adjusted).

Fig. 3 is a schematic flow chart of another adjustment method for a sending device according to an embodiment of the present application.

S302, the message is forwarded by the intermediate equipment between the sending equipment and the detecting equipment, and when the queue backlog length exceeds a set threshold or meets other specific conditions, the intermediate equipment can add an ECN mark or other state information in the forwarded message;

s303, after receiving the message with the ECN mark, the detection device counts or further processes the ECN mark (or other state information), and after a specified time period or after cumulatively receiving a specified number of messages, according to the processing result, determines whether to inform the source device to adjust the DCQCN parameter and how to adjust, if so, generates a CNP message, carries a field requiring the adjustment parameter in the CNP message, and sends the CNP message to the sending device;

s503, the sending device receives the message carrying the parameter adjusting field from the detecting device, and adjusts the DCQCN parameters (for example, reduces the initial sending rate of the new data message flow) according to the adjusting parameter information carried in the message;

after the parameters are adjusted, the sending equipment sends the messages according to the adjusted DCQCN parameters, so that the burst flow in the network is reduced, and the network congestion is avoided.
