Problems solved by technology

[0004] However, in the prior art, since the data packets of this special structure are generated and transmitted based on the IP tunneling protocol, on the one hand, the data packets of this special structure can only detect the packet loss problem in the three-layer network structure, which is limited. On the other hand, the data packet of this special structure includes a multi-layer tunnel header, which is very different from the structure of the service data packet. Therefore, the process of transmitting the data packet of this special structure is different from the process of transmitting the service data packet. The process is also very different. It is difficult to accurately simulate the transmission process of the service data packet by transmitting the data packet of this special structure, which makes it difficult to effectively detect or otherwise deal with the problem of network packet loss, and the reliability is low.

Embodiment 1

[0101] refer to figure 1 , shows a flowchart of a method for determining a network data packet according to an embodiment of the present application, and the specific steps include:

[0102] Step 101, determine multiple nodes through which network transmission passes, and the multiple nodes include a starting node, an intermediate node, and a terminating node.

[0103] Since in the process of network transmission, the data packet may need to be transmitted between multiple nodes, and in the transmission process of any two nodes, the data packet may be lost, that is, the problem of network packet loss occurs. Therefore, in order to To facilitate the subsequent judgment of the node where the network packet loss occurs, the packet loss detection server can determine the nodes through which the network transmission passes.

[0104] Wherein, the packet loss detection server may include the aforementioned server deployed with software for determining network data packets.

Embodiment 2

[0123] refer to figure 2 , shows a flowchart of a method for determining a network data packet according to an embodiment of the present application, and the specific steps include:

[0124] Step 201: Receive and send statistics instructions for data packets, and send the statistics instructions to the current node after determining multiple nodes through which network transmission passes.

[0125] In order to avoid the problems of large limitations and low reliability that may be caused by network packet loss detection relying on special structured data packet information, that is, in order to reduce the limitations of network packet loss detection and improve the reliability of network packet loss detection, network transmission The multiple nodes in may not need to transmit the data packet of this special structure, but receive the data packet statistical instruction, so as to count and feed back the data packet information through the following steps, so that the packet l...

Embodiment 3

[0132] refer to image 3 , shows a flowchart of a method for determining a network data packet according to an embodiment of the present application, and the specific steps include:

[0133] In step 301, the packet loss detection server obtains the start node and the end node corresponding to the network transmission where the packet loss occurs.

[0134] Due to the large number of nodes that may be included in the communication network, any two nodes may need to communicate through network transmission, which may cause packet loss. Therefore, in order to facilitate the detection of network transmission with packet loss, In order to quickly determine whether there is indeed a packet loss node in the network transmission, improve the accuracy and efficiency of packet loss detection, and obtain the corresponding start node and termination node of the network transmission where packet loss occurs.

[0135] In the daily network transmission process, each node can determine whethe...

Description

technical field [0001] The present application relates to the field of communication technologies, and in particular to a method, device and system for determining network data packets. Background technique [0002] With the development of communication technology, the scale of the communication network becomes larger and larger, and the number or types of network devices included in the communication network are increasing rapidly. Each network device can be used as a node in the communication network, and each node can transmit data packets through network transmission, and then communicate. However, due to abnormalities in network equipment or lines, the transmitted data packets may be lost during the communication process, thereby reducing the reliability of communication. Therefore, it is necessary to deal with the problem of network data packet loss (packet loss). [0003] In the prior art, for a path that may have a packet loss problem in network transmission, the st...
