Embodiment Construction
[0052] The technical solution of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments, and the following embodiments do not constitute a limitation of the present invention.
[0053] The present invention takes figure 1 As an example, a self-organizing P2P architecture service sharing system includes at least one node group, and each node group includes at least one enterprise node. Each enterprise in the system is displayed as a node, which provides shareable services to the outside world. Each node group dynamically gathers enterprise nodes that provide similar services, and selects the node with the best reputation as a core node through multi-criteria credit evaluation, also known as a super node, and other enterprise nodes in the node group are called leaf nodes. node. In the process of service discovery, the service request is firstly routed to the appropriate super node, and then further routed t...

The invention discloses a service sharing method of a self-organizing P2P organization and a system of the service sharing method. The service sharing method divides enterprise nodes joining service sharing into a plurality of node groups according to similarity of service provided by the enterprise nodes, selecting one super node in each node group, taking other enterprise nodes as leaf nodes, the super node maintains a credible friend super node pointer table, and routing service requests among the node groups. A service sharing system at least comprises one node group providing similar service, the node group comprises at least one enterprise node, simultaneously the node group is provided with one super node, and the super node is provided with the credible friend super node pointer table. According to the invention, node groups are divided and the super nodes are set, and service discovery communication link cost is small. Simultaneously, the joining or leaving of the enterprise nodes cannot influence all the enterprise nodes, the super nodes are relatively stable, and no expensive network maintenance cost can be generated.
Description
technical field [0001] The invention belongs to the technical field of service sharing, and in particular relates to a service sharing method and system of an ad hoc P2P architecture. Background technique [0002] With the rapid growth of the Internet and the continuous globalization of enterprises, the virtual enterprise VE (Virtual Enterprise) has gradually become a new information management technology and engineering management paradigm. It is a temporary alliance based on information network technology, resource sharing, cost sharing, cooperation and mutual benefit formed by opening up markets or jointly responding to other competitors. Compared with traditional enterprises, virtual enterprises have heterogeneous, dynamic, autonomous and distributed characteristics, which make their resource sharing have great difficulties and obstacles. Therefore, how to build a resource sharing platform that can adapt to the characteristics of virtual enterprises on the basis of info...
