Embodiment Construction

[0045] In the present invention, the peer-to-peer network is set to include multiple groups, and each group includes a group proxy node (Surrogate Node) and one or more common nodes; when the common nodes in the peer-to-peer network need to select a transit node , initiate a transfer query request to the group proxy node of the group to which it belongs, and the group proxy node selects a transfer node.

[0046] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0047] Such as figure 2As shown, the P2P VoIP service system includes multiple groups and P2P guide servers, and each group includes a group agent node and one or more common nodes (or called common peer nodes). interconnected to form a P2P network.

[0048] The P2P guide server provides ordinary nodes with information query services related to group proxy nodes where the nodes are located; provides group proxy nodes with other group prox...

Abstract

The invention discloses a method and a system for selecting a transit node of a voice over internet protocol service in a peer-to-peer network, wherein the method comprises the following steps of: setting the peer-to-peer network to comprise multiple groups, wherein each group comprises a group proxy node and one or more common nodes; and when the common nodes in the peer-to-peer network need the selection of the transit node, initiating a transit query request to the group proxy node of a per se ownership group, and selecting the transit node by the group proxy node. According to the method, the peer-to-peer is divided into multiple groups, and all member nodes in the groups perform transit node selection through the group proxy node, so the transit network maintenance cost is greatly reduced, and a more large-scale network can be supported.

Description

technical field [0001] The invention relates to the field of communication, in particular to a method and system for selecting a transfer node of an Internet telephone service in a peer-to-peer network. Background technique [0002] VoIP (Voice over Internet Protocol, VoIP) is a service that compresses and packets analog voice signals, and transmits voice signals on an IP network in the form of data packets. It is also called Internet telephony or IP telephony. VoIP is one of the important ways of voice communication at present, and it is also the main development direction of voice communication in the future. As a kind of voice service in the telecommunication network, the VoIP service also has high requirements on the voice quality. [0003] A P2P (Peer-to-Peer, peer-to-peer) network is an important way to develop a VoIP service network. A P2P network is usually a cross-region and cross-operator overlay network. Due to the operational strategy problems between Internet ...
