Problems solved by technology

[0004] When terminal nodes in the prior art obtain content, because the P2P system is not targeted when selecting content registration nodes, it often occupies more network resources, which is likely to cause a waste of network resources

Embodiment 1

[0025] see figure 1 , this embodiment provides a method for obtaining content, and the process of the method is as follows:

[0026] 101: Receive the network access request sent by the terminal node, the network access request is used to obtain the address of the content registration node, and the content registration node has registered the address of the content providing node with the content required by the terminal node;

[0027] 102: Select a simulation content registration node according to the location of the terminal node, the simulation content registration node has registered the address of the content providing node with the content required by the terminal node, and the distance between the simulation content registration node and the terminal node is smaller than that of other content registration nodes and the distance to the terminal node;

[0028] 103: Send the address of the simulation content registration node to the terminal node, so that the terminal node...

Embodiment 2

[0046]This embodiment provides a method for obtaining content, which optimizes the use of network resources without modifying the existing P2P system, thereby reducing unnecessary remote traffic, accelerating content transmission, and improving user experience . For ease of description, this embodiment takes a local DNS (Domain Name System / Service, domain name system / service) device and an application layer gateway to jointly complete the redirection function as an example, and describes the method provided in this embodiment in detail. see figure 2 , the method flow provided by this embodiment is specifically as follows:

[0047] 201: The local DNS device receives the DNS query request sent by the terminal node to access the network server. After the local DNS device performs the query through the DNS routing line, it returns the DNS query result to the terminal node. The DNS query result carries HTTP ALG (Application Layer Gateway, Application layer gateway) to instruct t...

Embodiment 3

[0073] see image 3 , this embodiment provides a redirection node, the redirection node includes:

[0074] The receiving module 301 is configured to receive a network access request sent by the terminal node, the network access request is used to obtain the address of the content registration node, and the content registration node has registered the address of the content providing node with the content required by the terminal node;

[0075] The selection module 302 is used to select a simulated content registration node according to the position of the terminal node, the simulated content registration node has registered the address of the content providing node with the content required by the terminal node, and the distance between the simulated content registration node and the terminal node is smaller than other The distance between the content registration node and the terminal node;

[0076] The sending module 303 is configured to send the address of the simulation c...

Abstract

Disclosed are a content acquisition method and a redirection node, belonging to the information field. The method includes: receiving a network access request sent by a terminal node, with the network access request being for acquiring the address of a content register node which has registered the address of a content providing node with the content required by the terminal node; selecting a simulation content register node according to the location of the terminal node, with the distance between the simulation content register node and the terminal node being shorter than that between the other content register nodes and the terminal node; and sending the address of the simulation content register node to the terminal node, so that the terminal node acquires the required content by way of querying the address of the content providing node from the simulation content register node. In the present invention, the selection of the content register node is more pertinent by way of selecting the simulation content register node according to the location of the terminal node, which not only can optimize the utilization of the network resources but also unnecessary remote traffic can be reduced.

Description

technical field [0001] The invention relates to the field of information, in particular to a method for acquiring content and a redirection node. Background technique [0002] With the continuous increase of people's demands on the network, P2P (Peer-to-Peer, peer-to-peer) technology is more and more widely used. In the P2P system, the terminal nodes act as servers for each other, and each terminal node can directly connect to the terminal nodes of other users to exchange files to obtain the required content, making communication on the network easier, more direct sharing and interact. [0003] When acquiring content, a terminal node in the prior art first accesses a Web server through an HTTP (HyperText Transfer Protocol, hypertext transfer protocol) protocol to obtain an address of a content registration node. Among them, the content registration node is responsible for registering what content each terminal node has in the P2P system, so as to provide query service when...
