Embodiment Construction

[0033] The technical solutions in the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the present invention. Apparently, the described embodiments are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0034] The super node selection method of the present invention is applied in a P2P network including a plurality of network nodes, and the network nodes may be various network servers.

[0035] The following combination figure 1 , detailing the super node selection process of the present invention. Such as figure 1 As shown, the super node selection process includes the following steps:

[0036] Step 11, each network node calculates the average online duration, processing index and cen...

Abstract

The invention provides a super node selection method and apparatus. An energy node of a current node is calculated and broadcasted according to an average online time, a processing index and a centrality of the current node, the energy value broadcasted by a neighbor node is received, and the network node corresponding to the maximum energy value is selected to serve as a super node. The online time, the current information processing ability and the link connection degree with the neighbor node of the network node are fully considered and are used as the selection reference of the super node, so the selected super node is more proper, the network load balance is guaranteed, the response time and the network overhead of information interaction are reduced, the network topology structure is more stable, and the network performance is improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a super node selection method and device. Background technique [0002] The unstructured P2P network overcomes the single point of failure of the centralized P2P network and has high search efficiency. It uses nodes with high performance as super nodes, manages ordinary nodes in its group through super nodes and responds to the query requests of ordinary nodes. The task of the super node includes not only the work as a common node group in the common node group, but also the contact task with other super nodes in the upper node group, and also plays a great role in the backup of resources. Therefore, super nodes play a very important role in the entire P2P network structure and are the link connecting the upper and lower networks. A super node selection method suitable for unstructured P2P networks can effectively reduce the response time of information interacti...
