Embodiment Construction

[0043] See attached picture. The network in the figure includes P2P nodes such as NN, FN, SN, and CN, and also includes VoIP terminals, softswitches and media gateways.

[0044] SN-1, SN-2: Super nodes in the P2P network, responsible for managing NN registration, FN allocation, and policy delivery

[0045] FN-1, FN-2: Forwarding nodes in the P2P network, responsible for providing forwarding services for NN

[0046] NN-1, NN-2, NN-3, NN-4, NN-5, NN-6: Common nodes in the P2P network, and also members of the VoIP system. in:

[0047] NN-1, NN-2, NN-3, and NN-4 correspond to terminals in the VoIP system.

[0048] NN-5 corresponds to the softswitch in the VoIP system.

[0049] NN-6 corresponds to the media gateway in the VoIP system.

[0050] 1. The entire P2P network is divided into 3 layers and 4 roles

[0051] Layers 1-1 and 3 are ordinary node layer, super node layer, and central node layer respectively.

[0052] 1-2, 4 roles are:

[0053] NN: Ordinary node, does not p...

Abstract

The present invention provides a P2P method supporting VoIP communication. A VoIP terminal and a server are all one node in the P2P network, and all nodes form an overlay network in the P2P network. The method of the invention comprises establishing the P2P network, selecting and establishing path. The whole P2P network is divided into three layers and four roles, wherein the three layers are a common node layer, a super node layer and a middle node layer. The four roles of P2P nodes are the following: NN: common node, FN: forwarding node, SN: super node, and CN: middle node of P2P network. Firstly the NN needs to be registered to SN. The SN receives the registration of NN/FN. The CN takes charge of establishing various regulations and strategies, at the same times takes charge of information exchange between SN-1 and SN-2, receives the registration of SN, manages the total network FN list, transmits an FN list to the SN and transmits a strategy to NN/FN. The VoIP and medium flow are all transmitted through a virtual path combined between NN/FN.

Description

technical field [0001] The communication of the present invention relates to the technical field, in particular, a P2P method supporting VoIP communication. Background technique [0002] At present, the development of P2P technology is changing with each passing day, and various P2P applications are emerging in an endless stream. In the beginning, P2P applications were mainly used for file sharing and transmission, and the main representative software included Napster, BT, eMule, etc. The main feature of these P2P is to share files, file transmission, there is no requirement for real-time. The emergence of Skype extends the P2P application to the VoIP (Voice Communication) field, realizes the transmission of real-time media streams on the P2P network, and greatly promotes the development of P2P technology. [0003] Currently, the application of real-time media transmitted in P2P networks is mainly the live broadcast of Internet TV. One difference between live IP TV and Vo...
