The embodiment of the invention discloses a data obtaining method and device. The data obtaining method includes the steps that data source nodes meeting a connection request are grouped according to a factor affecting the connection quality; in each group of data source nodes, the matched data source nodes are hit according to the Hash mapping rule; according to the connection quality index of the data source nodes, one data source node with the optimal connection quality is selected from the hit and matched data source nodes in each group; data are obtained from the data source nodes with the optimal connection quality. According to the data obtaining method and device, the data source nodes with the optimal connection quality can be selected according to the connection quality index and are more suitable for being connected with a client side, so that the transmission efficiency of the process of obtaining the data from the data source nodes is higher, and the transmission efficiency of a whole network is improved.
Description
technical field [0001] The present invention relates to the technical field of Internet, in particular to a data acquisition method and device. Background technique [0002] In a tree-structured Internet, when the current client sends a connection request to a certain server, the server receiving the connection request may not have response data locally, and needs to send a data request to its parent node to obtain the response data. Take the Internet network structure of reverse proxy as an example. When a client in the external network needs to connect to a server in the internal network, the proxy server receives the connection request from the client in the external network, and then forwards the connection request to the server in the internal network. The server is the data source node in the internal network, and returns the data obtained from the data source node in the internal network to the client that sends the connection request in the external network.
