IMPROVED STORAGE PERFORMANCE

摘要

A network (10), such as a computer network, is disclosed. The network (10) has a plurality of nodes (20; 120) and includes a first node (30, 130) for storing pieces of a digital object and having a storage (40, 50; 140, 150). A plurality of connections are present between the first node (30, 130) and the plurality of nodes (20; 120). The first node (30, 130) has a requester for requesting one or more pieces of the digital object, a transmitter for transferring one or more pieces of the digital object to at least one further node among the plurality of nodes (20; 120), a receiver for receiving content availability messages from at least some of the plurality of nodes, and a sender for sending a limited content availability message to at least one further node (20; 120) among the plurality of nodes (20, 120). The limited content availability message indicates a subset but not all of the pieces of the digital object available through the first node (30; 130). A method of providing pieces of digital object from a first node (30, 130) to a plurality of nodes (20, 120) in a network (10) is also disclosed which includes a first step of sending to at least one further node (20b, 120b) among the plurality of nodes the limited content availability message. In the second step a request for pieces of the digital object is received from at least one of the plurality of nodes (20, 120) and finally in the third step one or more pieces of the digital object are transferred to the at least one of the plurality of nodes (20,120).
