Data source return method and device

Abstract

The invention discloses a data source return method, comprising the following steps: a request terminal sends out a request for downloading resources to a server; the server searches the data sources with the resources according to a resource mark of the resources which are requested to be downloaded; the server acquires the request terminal requesting for downloading the resources and the property indexes of the resources transmitted by each data source and returns corresponding data sources to the nodes of the requested resources according to the property indexes. The invention simultaneously discloses a data source return device. The method and the device of the invention can be applied to lead the server to return the corresponding data sources to the nodes of the resources which are requested to be downloaded according to the request terminal requesting for downloading the resources and the property indexes of the data sources with the resources, thus improving the transmission speed of the resources between the request terminal requesting for downloading the resources and the returned data sources.

Description

technical field [0001] The present invention relates to the technical field of point-to-point (P2P) connection, in particular to a data source return method and device in the technical field of P2P connection. Background technique [0002] P2P is a peer-to-peer Internet technology. P2P technology enables the computer of users who need to download resources to directly connect to other users' computers and download resources, instead of connecting to the server to download resources as in the past, and P2P technology makes full use of Network bandwidth resources effectively reduce the load on the server. [0003] figure 1 It is a schematic diagram of a P2P network topology structure in the prior art. Such as figure 1 As shown: the index of each resource in each data source is stored on the server 11 in the network in the form of <resource identification (ID), <data source ID, data source Internet Protocol (IP) address>>, Wherein, the resource ID is used to ide...

Problems solved by technology

Among them, the random return method is that the central server randomly selects several data sources to return to the requesting terminal requesting resources. This method is relatively blind, and in most cases, the transmission speed of resources cannot be maximized; The central server will return all data sources with the resource ID of the requested resource to the requesting terminal requesting the resource, and the requesting terminal will compare and select the data source that needs to be transmitted with the resource. This method consumes a lot of resources. Data source, and within the time of comparison and selection, the resource transmission may have been completed, especially when there are many data sources for a certain resource, this method is even more inadvisable
