Embodiment Construction

[0025] The following combination figure 1 An embodiment of the present invention is described:

[0026] figure 1 It is a flowchart of a method for sending a node list in an embodiment of the present invention. The method includes:

[0027] 102. Receive a node list request message sent by the client, where the node list request message is used to request a node that can provide a specific resource.

[0028] In order to download a specific resource in P2P mode, the client needs to obtain the information of the nodes that can provide the resource, so the client sends a node list request message to the server (appTracker or pTracker). The server receives the node list request message, and in some specific application scenarios of the embodiments of the present invention, a Deep Packet Inspection (Deep Packet Inspection, DPI) device receives the message in an intercepted manner.

[0029] 104. Obtain a node list capable of providing the specific resource according to the node li...

Abstract

The invention relates to the field of network communication, in particular to a method and equipment for sending a node list. The method comprises the following steps of: receiving a node list request message sent by a client, wherein the node list request message is used for requesting a node capable of providing a specific resource; acquiring the node list capable of providing the specific resource according to the node list request message; and sending nodes in the node list to the client in batches according to the priority level of each node in the node list and the client information ofthe client, wherein the priority level of each node is determined according to network topology information or an operator strategy. In the technical scheme provided by the embodiment of the invention, the nodes are sent to the client in batches according to the client information and the priority level of each node in the node list, so that P2P flow optimization efficiency is improved.

Description

technical field [0001] The invention relates to the field of network communication, in particular to a node list sending method and device. Background technique [0002] Now, there are a large number of peer-to-peer (Peer-to-Peer, P2P) network applications on the Internet, such as bittorrent (Bittorrent), electric mule (Emule), etc., and the large amount of P2P traffic brought by these P2P applications accounts for more than half of Internet traffic . A P2P network generally consists of a server (such as appTracker in bitstream) and nodes (Peer). When obtaining resources, the peer first obtains the node list (Peerlist) information from the server, and then performs signaling interaction and data transmission with other peers in the Peerlist according to the Peerlist information. Because neither the server nor the peer of the P2P network is aware of the network topology, a large amount of cross-domain and cross-Internet Service Provider (Internet Service Provider, ISP) traf...
