Problems solved by technology

Although structured P2P has high efficiency, load balance, and strong scalability, the maintenance mechanism of the DHT structure is relatively complicated, especially the network fluctuations caused by the frequent addition and exit of nodes, which is precisely an important feature of the P2P network and will greatly Increase the maintenance cost of DHT and easily generate routing table errors, which seriously affects its stability

Embodiment Construction

[0027] refer to Figure 5 , the present invention includes an upper network 1 and a lower network 2, the upper network 1 adopts a structured P2P network, and the lower network 2 adopts an unstructured P2P network. The upper structured P2P network adopts a ring structure 3 composed of k virtual nodes VN. The underlying unstructured P2P network is a circular distribution composed of k group structures 4, each group structure 4 is composed of m super nodes SN and n general nodes N, all general nodes N Random connections among all supernodes SN are connected to each other, and each general node is connected to at least one supernode, such as Figure 6 shown. Figure 6 In , VN represents a virtual node, S represents a super node, and N represents a general node. The number of virtual nodes k = U × p , Number of super nodes m = log 2 ...

Abstract

The invention discloses a secondary P2P static network for a mixed layer. The P2P static network comprises a structurized P2P top network and a non-structurized P2P down network. The structurized P2P network is an annular structure (3) composed of virtual nodes numbering k; and the non-structurized P2P network is an annular distributing structure composed of group structures numbering k. Each group structure is composed of super nodes numbering m and common nodes numbering n. All the super nodes in each group structure are all provided with routing lists; and the routing lists commonly finish message passing among all the virtual nodes in the top network. The common nodes in the down network are connected randomly; the super nodes are connected mutually, and each common node is at least connected with a super node. Each virtual node of the up network is corresponding to one group structure; and all super nodes in each group structure commonly finish the maintenance of the virtual nodes and the management of the common nodes in the group. The P2P static network has the advantages of high efficiency and strong stability, and can be used as a sub structure of resource distribution and network query.

Description

technical field [0001] The invention belongs to the technical field of network communication, in particular to a point-to-point static network structure, which can be used as the underlying structure of resource distribution and network query. Background technique [0002] In recent years, with the progress and development of peer-to-peer network technology, the network file sharing system based on peer-to-peer P2P has gradually become one of the most popular applications in the Internet. P2P technology has developed from the first-generation centralized index service model to the third-generation model based on distributed hash tables, referred to as DHT. The P2P-based network file sharing system has gradually become more powerful with the development of P2P technology. Rich content. [0003] With the rapid growth of Internet users and data volume, traditional network file sharing systems based on centralized P2P and unstructured P2P have gradually become inefficient and o...
