A demand on a server farm or local area network for a farm or network resource is satisfied. The farm or network has a demand director server, a first resource server having a first resource, and a second resource server having a second, different, resource. The director server is aware of what resources are held on the first and second resource servers. In response to a request for one of the first and second resources, one of the first and second resource servers is selected to serve out the requested resource and direct the request to the selected one of the first and second resource servers. The demand server selects an appropriate one of the resource servers to receive the request using its knowledge of where the requested resource is located.

Method of satisfying a demand on a network for a network resource

A management data distribution apparatus has, a control unit, a buffer memory element, at least one input port, and a telecommunications output. The at least one input port is arranged to receive management data from devices located within a network and to pass the management data to the control unit. The control unit is arranged to control output of the management data via the telecommunications output to a remote monitoring site over a telecommunications network. The control unit is also arranged to store management data arriving at the at least one input port when the said telecommunications output is in use in the buffer memory element, temporarily.

Remote monitoring of computer devices

The availability of requested network resources in a network of servers, each having associated network-servable resources of a specific kind is maintained. Resource data and resource-serving application software serve out the resource data and dynamically distribute capacity to serve out servable resources between the resource servers dependent on demand for the resources. The capability of the network as a whole to serve out a particular resource dependent upon the level of demand for the particular resource is thereby varied. The capacity to serve out servable resources is distributed between the resources without necessarily moving the resource data itself between the servers by distributing: resource-serving application software and/or installation software adapted to install resource-serving application software.

Systems and methods of maintaining availability of requested network resources

A method of serving out video over a network of video servers includes evaluating a capacity of the network as a whole to serve out specific video items by establishing, for each video server in the network, an established ability of each server to serve out the specific items that are potentially servable from each video server. The method further includes using the established abilities of each video server to evaluate an overall capability of the network as whole to serve out each of the specific video items. The method also includes varying the overall capability to serve out at least a selected one of the specific video items in accordance with the overall capability of the network.
