Grid Resource Discovery Model Based on Improved Architecture and Multicast

In order to solve the shortcomings of traditional resource discovery mechanism. Many sophisticated strategies are implemented to ensure that the grid resource discovery service has good scalability and efficiency. Nodes are divided into different domains, and we use improved distributed hash table technology to achieve higher local routing efficiency; the combination of the tree overlay network and hierarchical structure improves the overall scalability. The messages are transmitted among the management nodes through multicast, reducing the network load as well. The experimental results show that: the model reduces the query time and improves the grid resource discovery efficiency.
