Problems solved by technology

These two methods have their own disadvantages: the overhead of resource maintenance in the distributed hash table method is very large, does not support multi-key search, and is easily affected by network dynamics; flooding requests will be generated during the resource search process. Large network traffic, poor search performance for scarce resou

Example Embodiment

[0115] Examples:

[0116] Using the general resource management method under the hybrid peer-to-peer network environment described in the present invention, the laboratory provides 1 startup server, three road sign servers, and 10 ordinary PCs, and each PC is added according to the Poisson distribution law Topological organization, and then run instant messaging and file sharing services based on peer-to-peer network technology simultaneously on each PC. The hardware configuration of the PC is as follows:

[0117] Machine name

[0118] PCs 1-10 are called node 1, node 2, ... node 10, respectively.

[0119] The constant thresholds selected in this example are as follows: the resource capacity threshold is 50 megabytes; the delay represented by the ring zone boundary of the multi-analysis ring structure topology is set to 15 ms, 50 ms, 100 ms, and 300 ms; the road sign delay threshold 300 milliseconds; the delay threshold is 50 milliseconds; the upper limit of the number o...

Abstract

The invention discloses a general resource management method in a hybrid peer-to-peer network environment, comprising a plurality of steps that: (1) all the resources of a node P are described uniformly by the node P, the internal resource of the higher-level service corresponds to the description of the general resource; (2) the node P is added into a hybrid topology, then the node is determined as a role of a strong node or a weak node; (3) resource releasing, resource searching and resource deleting are respectively carried out according to the different management operations. The invention has the advantages that: the resource management opens to a plurality of services based on peer-to-peer network technology due to the standard definition of the general description for the resource; in addition, the effective management of the uniform resource is realized in the dynamic network environment by the construction of a peer-to-peer network environment with the mutual mixture of distributed Hash table and delayed aggregation multi-analytical annular topology; a plurality of services are supported by using open resource management method, so the waste of network bandwidth and node calculation ability is reduced, moreover, the dynamic property of the system and the effectiveness of resource searching is guaranteed.

Description

technical field [0001] The invention belongs to the field of computer applications, and is a general resource management method in a mixed peer-to-peer network environment. Background technique [0002] Peer-to-peer network technology is a new technology emerging in recent years that uses the computing power of terminal desktop PCs and terminal network bandwidth to share files between users. It has many advantages such as flexibility, scalability, robustness, and load balancing. , so it also provides a good technical foundation for the popularization of some network multimedia services such as streaming media services and voice services. Nodes based on the peer-to-peer network can share the existing data with each other without all concentrating on a single server to obtain data, thus greatly reducing the burden on the server and the network. [0003] In services based on peer-to-peer network technology, data is no longer obtained from a single server, and users need to ado...
