Embodiment 1

[0025] refer to figure 1 , which shows a flow chart of the steps of a data sending method provided in Embodiment 1 of the present disclosure, which may specifically include the following steps:

[0026] Step 102, according to the node tree and the node information of each node in the node tree, determine the optimal path from the root node in the node tree to the target child node.

[0027] There are multiple nodes in the network, each node stores corresponding data, and the nodes are intercommunicated, and data transmission can be performed, and each node can represent a server. Each node in the network can be used as a data source node, and the surrounding nodes can send data requests to the data source node to obtain corresponding real-time data.

[0028] After the data source node is determined, the data source node is used as the root node, and the node requested from the data source is used as the child node to build a node tree, wherein the node tree includes multi-lev...

Embodiment 2

[0034] refer to figure 2 , which shows a flow chart of the steps of a data sending method provided in Embodiment 2 of the present disclosure, which may specifically include the following steps:

[0035] Step 202, according to the node tree and node information, determine the weight of each path from the root node to the target child node.

[0036] There will be one or more routing paths from the root node to the target child node in the node tree, and any one of the routing paths will include multiple intermediate child nodes. In addition, in order to obtain the information of each sub-node conveniently, a corresponding server or device can also be set up to collect the information of each sub-node in real time and provide the obtained information to the scheduling server. After the scheduling server determines the plurality of intermediate child nodes included in the corresponding path, the information obtained above may be based on information such as the identifier, name ...

Embodiment 3

[0051] refer to image 3 , which shows a structural block diagram of a data sending device provided in Embodiment 3 of the present disclosure; specifically, the following modules may be included:

[0052] A determining module 302, configured to determine the optimal path from the root node in the node tree to the target child node according to the node tree and the node information of each node in the node tree, wherein the node tree includes multi-level child nodes , the root node of the node tree is a data source node, and the target child node is a node that sends a data request to the data source node.

[0053] The sending module 304 is configured to send target data to the target child node through the root node according to the optimal path.

[0054] According to the node tree and the node information of each node in the node tree, the embodiments of the present disclosure determine the optimal path from the root node in the node tree to the target child node; according...

Abstract

The embodiment of the invention provides a data transmission method and device. The data transmission method comprises the steps of determining an optimal path from root nodes in a node tree to a target sub-node based on the node tree and node information of each node in the node tree, wherein the node tree comprises sub-nodes at multiple levels, the root nodes of the node tree are data source nodes, and the target sub-node is a node which transmits a data request to the data source nodes; and transmitting target data to the target sub-node through the root nodes based on the optimal path. The optimal route from each root node to each sub-node can be determined through the node tree, and then data transmission can be carried out based on the optimal path, so that a network pressure is reduced, and data transmission time is also shortened.

Description

technical field [0001] The present disclosure relates to the technical field of computer networks, and in particular to a data sending method and device. Background technique [0002] Various resource data are stored in nodes in the network, and users obtain corresponding resource data by accessing nodes. [0003] During live video broadcasting, real-time video data is stored in a certain node in the network, and the nodes around the node will send data requests to it to obtain live real-time video data; however, when the node storing video data sends When the child node of the data request sends the corresponding video data, due to the inconsistency of the path, it not only increases the load of the network, but also may prolong the time of data sending. [0004] Therefore, a problem urgently needed to be solved by those skilled in the art is: to provide a data sending solution to solve the problem in the prior art that the paths for nodes in the network to send data are n...
