Abstract
A network including a plurality of nodes which communicate over a communications link includes client nodes which are used by users and server nodes. At least one of the server nodes is a management server node, and other server nodes may comprise backup server nodes or software distribution server nodes. To initiate, for example, backup service, the management server node transmits a message to the backup server node to enable it to perform the backup. To initiate software distribution service, the management server node determines the nature of the service, such as downloading new versions, auditing use for licensing purposes, and the like, and transmits a message to the software distribution server node to initiate the operation. The network may include master and slave management server nodes, backup server nodes and software distribution server nodes to further divide the control of the respective operations.
