Problems solved by technology

The key problem of this algorithm is to initialize the central node. This is a difficult problem, which is usually solved by a centralized method, so the CDC method is not a fully distributed method.

Embodiment

[0080] based on figure 1 The shown flow chart of the realization of the overall technical solution for building a clustered P2P network distributed aggregation provided by the present invention, figure 2 A flow chart of a method for constructing a clustered P2P network distributed aggregation in an embodiment of the present invention is shown. In this implementation, the nodes that newly join the P2P network adopt a centralized scheme to obtain the information of the current active nodes, and the method includes the following steps:

[0081] Step 201: A node that newly joins the P2P network sends a join request to obtain current active node information to the centralized service node.

[0082] Step 202: After receiving the join request, the centralized service node randomly selects a certain number of current active nodes, and returns the physical information of the selected active nodes to the node that sent the join request;

[0083] The physical information of the nodes ...

Abstract

The method comprises: a) the newly added P2P network node establishes an initialization connection between itself and the currently active node; b) the nodes that have already established an initialization connection optimizes the initialization connection established in order to build a P2P network system with cluster-based architecture. By the invention, it is implemented gathering nodes in P2P network into different clusters so as to improve the gathering degree and connectivity, which can make the gossip release mechanism either get an ideal diffusing speed or have certain reliability.

Description

technical field [0001] The present invention relates to the technical field of peer-to-peer (Peer-to-Peer, P2P) network, in particular to a distributed aggregation method for constructing a clustered P2P network. Background technique [0002] A P2P network is a virtual distributed network formed independently by hosts, and network participants share a part of their hardware resources, such as processing power, storage capacity, network connection capacity, printers, etc. These shared resources require the network to provide resources such as services and content, and these resources can be directly accessed by other peer nodes (Peer) without going through an intermediate entity. Nodes in this network are not only providers of resources such as services and content (Server), but also acquirers of resources such as services and content (Client). That is, the status of each node in the network is equal, and each node not only acts as a server, provides services for other nodes...
