The speed measurement scheduling server initially screens all the speed measurement nodes by the terminal access network type and the network level position of the speed measurement node, and then the speed measurement scheduling server sends the speed measurement node to the speed measurement node. The speed measurement request is broadcast, and after the reverse network test and feedback of the speed measurement nodes, the speed measurement scheduling server finally decides the set of nodes participating in the speed measurement, constructing a distributed decentralized speed measurement network architecture, which can be applied to the speed measurement mode in the 5G network environment. Compared with related technologies, the embodiments of the present disclosure at least include the following beneficial effects:

If ordinary users have idle computing resources, they can also apply to join the distributed speed measurement network as a speed measurement node, so as to realize the decentralization of the speed measurement network architecture; 3) Decentralization The distributed speed measurement mode uses the speed measurement node to contact the terminal to be tested in reverse, and collects the network status information between each speed measurement node and the terminal to be tested, and then the speed measurement scheduling server selects a number of optimal speed measurement nodes for the terminal to be tested. Effectively reduce the load of the operator's speed measurement scheduling server and transmission network in the existing mode, and minimize the occupation of network resources; 4) For 5G terminal users, the embodiments of the present disclosure can be preferably found to be deployed in the 5G access network or 5G core network To avoid occupying network resources outside the 5G mobile core network as much as possible, avoid occupying network resources of the external bearer network or backbone network, and improve the test accuracy of 5G network speed.

In the embodiments of the present disclosure, the terminal to be tested generally refers to the terminal used by the user who needs to perform network speed measurement, which may be accessed through a mobile network 3G/4G/5G, a broadband access network (such as Ethernet, optical Internet access, cable TV access, corporate broadband access) and other network access methods are the initiator of the speed measurement process and the recipient of the final result.

In the related technology, the speed measurement node that is closest to the terminal to be tested is screened out based on the distance, which has high requirements on the bandwidth and capability of the speed measurement node, and because the terminal to be tested and the speed measurement node may go through multi-level routing, and even encounter Different network architecture modes are easily affected by heterogeneous networks, network loads, and server loads, and it is difficult to guarantee the accuracy of speed measurement. As a result, the current test scheme can only test the minimum bandwidth between the terminal to be tested and the test node, but it is difficult to test the terminal and the test node. The network bandwidth between access networks, especially when 5G terminals and 5G networks are gradually popularized, it is more difficult for current speed measurement technology to accurately measure the maximum bandwidth between terminals and access networks.

(1) Screening according to the network access type of the terminal to be tested: if the access network of the terminal to be tested is a mobile access network, the terminal using the mobile access network only recommends the speed measurement node located in the mobile network, and at the same time according to the Recommend by type priority: 5G access terminal === only recommend speed measurement nodes located in 5G network, 4G access terminal === recommend speed measurement nodes located in 5G and 4G networks, 3G access terminal === recommend located in Speed measurement nodes in 5G, 4G, and 3G networks; if the access network of the terminal to be tested is a fixed network access network, the terminal using the fixed network access network only recommends network speed measurement nodes located in the fixed network; further, in some In the embodiment, after selecting a number of first speed measuring nodes through the above process, (2) after filtering according to the network access type, further recommending according to the hierarchical position of the speed measuring node in the network architecture, if it is a mobile access network, then Select the speed measurement node based on mobile access network>mobile core network>mobile IP bearer network>backbone network; if it is a fixed network access network, perform speed measurement based on fixed network LAN>fixed network access network>MAN>backbone network node selection.

In step S12, the plurality of speed measuring nodes respectively perform network speed measurement on the terminal to be tested, so as to obtain speed measurement information of each speed measuring node on the terminal to be tested respectively.

Node speed measurement information. Compared with related technologies, each speed measurement node in this embodiment performs distributed and synchronous speed measurement, which can effectively improve the speed measurement efficiency of the terminal to be tested.

In step S13, the network access speed of the terminal to be tested is determined based on the speed measurement information.

In this embodiment, after the speed measurement scheduling server selects a number of corresponding speed measurement nodes, it sends prompt information to the speed measurement nodes to enter the speed measurement of the terminal to be tested, and each speed measurement node initiates distributed speed measurement to the terminal to be tested after receiving the prompt information Request, and start the speed measurement respectively, after the speed measurement of each speed measurement node, return the respective speed measurement information to the speed measurement scheduling server, the speed measurement scheduling server obtains the bandwidth results returned by each speed measurement node, and sums them up, that is, the terminal to be tested The actual network access speed is based on the distributed speed measurement method provided by this implementation, the speed measurement process is more efficient, and the speed measurement results are more accurate.

In step S115, the plurality of second speed measurement nodes is selected as the plurality of speed measurement nodes.

Specifically, in order to further improve the efficiency and accuracy of speed measurement, after the speed measurement scheduling server in this embodiment selects the first speed measurement node, it does not directly use the first speed measurement node as the speed measurement node for speed measurement, but according to the Load conditions for further screening. For example, after being optimized by the speed measurement scheduling server, obtain a set A of several speed measurement nodes of the first speed measurement nodes, and then remove all speed measurement nodes in the set A whose load exceeds 30%, and obtain a set B of the second speed measurement nodes, and realize based on Several second speed measuring nodes in the set B measure the speed of the terminals to be tested.

Please refer to Fig. 4, Fig. 4 is a schematic flowchart of a speed measurement method provided by another embodiment of the present disclosure.
