Problems solved by technology

[0005] At present, there is no unified network protocol standard for P2P. The existing hybrid P2P combines the characteristics of centralized P2P and distributed P2P, but it also weakens the self-organization characteristics of P2P networks, and the dynamic adaptability of the network is limited.

Embodiment Construction

[0035] Based on the background of the third-generation P2P—hybrid P2P network, a hybrid structured P2P network is proposed: super nodes are replaced by DNA to form an upper layer network, which provides distributed network processing functions; and provides centralized network proxy functions for lower layer nodes. DNA identity and DNA quantity can be dynamically adjusted to better meet the requirements of network self-organization. When the network scale and network state change, the state of the nodes in the network and the communication connections between each other will be adjusted accordingly to adapt to the change of the network. Its technical solution mainly includes the following three aspects:

[0036] 1. Hybrid structured network model:

[0037]The first generation and the second generation of P2P networks are logically one layer, that is, the overlay network on the application layer. The third-generation P2P is a hybrid P2P network. The distribution of full-mesh ...

Abstract

The invention relates to a self-organizing method based on a composite structured peer-to-peer network, which comprises the following steps: establishing a two-layer structured logical network model, performing corresponding adjustments on the main machine communication in the network model along with the changes of the network size and the main machine performance, and performing corresponding maintenance on resources in the network so as to achieve the characteristics of self adaptation and self organization to better ensure the network performance . Simultaneously, the network size, the network running conditions, and the like are manageable, thus the network is a manageable P2P and the blank condition of P2P management is changed.

Description

technical field [0001] The present invention is to establish a hybrid structured peer-to-peer network, which fully considers the difference between node performance, has strong self-organization, manageability and expansion, and realizes self-organizing strategy. Background technique [0002] The application of peer-to-peer network (P2P) in the Internet has become one of the main applications of the Internet, and the P2P mode has also become the preferred mode of many new services. P2P has had an important impact on the entire Internet business model and supervision mechanism. [0003] P2P technology is widely used in file sharing, online video, Internet telephony, online games and other fields. With the characteristics of distributed resource sharing and parallel transmission, it provides users with more resources, higher available bandwidth and better services. quality. P2P nodes do not rely on central nodes but rely on network edge nodes to realize self-organization and...
