Architectural Models

• Model 1

The First Static Model with respect to Harvesting Nodes and doesn't involve any compression during the transfer of data among nodes.

• Model 2

The Second Static Model with respect to Harvesting Nodes and involves compression during the transfer of data among nodes.

• Model 3

The Third Static Model with respect to Harvesting Nodes and involves direct transfer of data from Harvest Nodes to the Cluster Nodes. Cluster Nodes are included inside the Grid.

• Model 4

The Fourth Static Model with respect to Harvesting Nodes and several Metadata Collection Nodes, each of them handling a pool of cluster nodes. Also Transfer of files is in compressed format.

• Dynamic Model

In the Dynamic Model, code for the harvester is shipped from the scheduler to any new node that wants to become the Harvester node. The job of harvesting will be issued from the scheduler.

• Digital Library Grid Setup

• High Performance Architecture
