Abstract: A process for requesting information, the process including generating a plurality of range requests using a client having a plurality of network interfaces, the range requests each corresponding to a data range of a data resource, transmitting, from the client having the plurality of network interfaces, a plurality of range requests to a server via the plurality of network interfaces, receiving, at the client and from the server, a plurality of segments via the plurality of network interfaces such that each segment is received via a network interface which transmitted the corresponding range request, each segment including a portion of the data resource, and reassembling the data resource using the plurality of segments.

Abstract: A network comprises nodes and links. In addition to a default topology there are backup configurations. Each node is inhibited from transferring data between nodes in at least one backup configuration. When a node detects a fault in the reception of data transmitted to a neighbouring node, it switches to a backup configuration in which the neighbouring node is inhibited. In one arrangement a backup configuration has at least one link which is restricted by having a high weighting so that it transmits data to a node only if that node is the final destination node for that data. Additionally, if the neighbouring node is the final destination, and routing of data is still unsuccessful in the backup configuration, the detecting node selects and switches to an alternate backup configuration in which the detecting node is inhibited.
