Embodiment Construction

[0035] In order to ensure the bandwidth requirements of service transmission in the network, the embodiment of the present invention provides a method for transmitting service data in a P2P network. The P2P network uses a P2P Bearer Control Protocol (P2P Bear Control Protocol, PBCP), and the PBCP includes 3 basic elements: The IP address of the endpoint, the port number used for the connection, the channel established after the connection, the concept of the IP address and port number and the TCP / IP protocol are the same, and multiple channels may be established when the connection is realized.

[0036] In order to support PBCP implementation, it is necessary to change the classification of existing routing nodes. At present, all routing nodes are divided into two categories, one is general nodes (General Node, GN), which are some weaker routers in the domain, and they are mainly responsible for routing information in the domain and forwarding information to super nodes. One i...

Abstract

The embodiment of the invention discloses a method for transmitting service date in P2P network; the method is that when a user node transmits data, the data which are provided with bandwidth requirements are preferably scheduled; the transmission velocity is confirmed according to the bandwidth requirements and the data are transmitted to routing nodes according to the transmission velocity; when the routing nodes forward data, the data which are provided with bandwidth requirements are preferably scheduled and transmitted to a next hop node. The embodiment of the invention also discloses a system for transmitting service data in the P2P network and user node equipment and routing node equipment. By adopting the invention, the bandwidth requirements for service transmission can be guaranteed.

Description

Technical field [0001] The invention involves the field of IP communication technology, especially a method, system, and device that transmits business data in a peer P2P network. Background technique [0002] With the development of peer to peer (P2P) network technology, the P2P network has gone through the first generation of the Napster system, the second generation representedP2P systems, these systems have demonstrated the charm of the P2P network.P2P network is expected to provide efficient routing and business service quality (QOS) guarantee services for the next generation of telecommunications networks. [0003] In order to meet the increasing requirements of business routing and network bandwidth resources, the P2P network structure adopts the ideas of the domain to divide the entire network into a smaller scale.Gn) and Super Node (SN).Among them, ordinary nodes are some weak routers or servers, which are responsible for routing of information in the domain; super nodes...
