Title: DATA TRANSMISSION METHOD AND SYSTEM
Abstract:
Disclosed are a data transmission method and system. The method comprises: a first designated sub-node receives a data acquisition instruction which is sent by a distribution manager, wherein the first designated sub-node is a sub-node at a lower level of a root node, requests data from the root node and sends the requested data to a second designated sub-node, the second designated sub-node is a node at a lower level of the first designated sub-node, each level is provided with a designated sub-node, other nodes at the same level as the designated sub-node are all set to be backup sub-nodes, and a communication index parameter between the designated sub-node and the root node is superior to a communication index parameter between the backup sub-nodes and the root node. In the present invention, a relatively small number of sub-nodes with better communication conditions are designated, among sub-nodes at each level, as designated sub-nodes to participate in data transmission, avoiding occupying too much bandwidth, improving a transmission speed and saving network costs.
