Abstract

In a peer-to-peer (P2P) system, in each individual transmitting peer (10), the incoming data stream is divided logically and with regard to time into different parts, which are buffered in a volatile memory (13) and are transmitted to the receiving peers (20, 30) on different paths by means of a peer-to-peer transmission mechanism (40). In a receiving peer (20), the received parts of the subdivided data stream are buffered in a volatile memory (21) and are reassembled into a complete data stream. Further, in the receiving peer (20), the parts of the subdivided data stream, buffered by the volatile memory (21), are copied into a persistent memory (22), from where they are copied back into the volatile memory (21) at a later point in time if necessary. A fraction of the received data is excluded from persistent storing by selecting parts of the subdivided data stream.
