基于三层P2P结构的网格资源发现模型

A Grid Resource Discover Model Based on Three-Layer P2P Structure

在现有P2P技术的基础上,设计并实现了一种三层P2P网络。在原有SuperNode P2P结构的基础上进行了改进并增加一层功能节点。该结构中功能节点被用来存储从各个SuperNode收集的特定种类的网格资源信息。通过增加功能节点层可以很好地提高目前基于P2P技术的资源发现的效率,并且有效减少单点失效的问题。

A three-layer P2P lookup model for grid resources is presented in this paper. This is a complement model of the existed super-node model of P2P. By adding a new layer upon the layer of super-node, the model can effectively improve the performance of lookup in the P2P environment and reduce the problem of single point of failures.
