Overal-node maitaining method in reciprocal network

Abstract

Characters are as following: first, a control server is configured for peer-to-peer network to manage states of global nodes, implement adding, updating, and detecting nodes etc, communication with each client, and defines data structure of dynamic information of storage node; next, according to C segment of IP address, the network is divided into sections; unique comparable ID is built for sections, and node table is built according to descending sort of ID; moreover, using first addresses of C segment as a IDs builds a table of first address according to IP address; using method of reducing by half to look up table of first address to implement adding, quitting, updating, and to maintain a table of neighbor nodes; finally, based on time of holding activation message, the method determines whether node is disabled according to threshold. The invention carries out periodic detection to assure performance between optimized nodes, and prevents local detached island in network.

Description

technical field [0001] The global node maintenance method in the peer-to-peer network belongs to the technical field of global topology maintenance of the peer-to-peer network. Background technique [0002] The peer-to-peer network is based on the point-to-point network transmission mode, which completely breaks through the defects of the traditional client / server mode, and has the characteristics of strong scalability, low cost, flexibility and convenience. In a peer-to-peer network, each relay node will exist both as a client and as a server, so that the transmission performance of the entire network depends largely on the topology of the network and the pre-provided neighbors for each node. The node's quality of service. [0003] In a peer-to-peer network, group members are usually organized according to two topologies, one is the control topology and the other is the data topology. The control topology is mainly used to maintain the global node status and network topolo...

Problems solved by technology

[0004] There are two traditional global node maintenance methods. One is simply to continuously detect neighbor nodes by the client, which leads to continuous changes in the topology structure. The rapid increase of traffic, in addition, when the client searches for neighbor nodes, it does not consider the relationship between the physical location of the nodes; another maintenance method is to completely maintain the topology structure by the super node (equivalent to our control server), which will be formed in the future The topology of the network is also managed by supernodes. The problem with this method is that supernodes will become a single point of failure in the network. Once the supernodes are lost, the network will collapse immediately
