Data transfer method for e.g. Internet, involves transmitting query for destination-peer-device from one of peer-to-peer-networks to one of peer-devices in network under information of one of network addresses of another peer-device

摘要

The method involves providing nodes-addresses (NID1, NID1`, NID2`) in their respective peer-to-peer-networks (P2P1, P2P2) for each peer-device (P1, P1`, P2`). Network-addresses (IP1, IP1`, IP2`) are provided in a superior communication network. A query (S1) for the destination-peer-device (P2`) is transmitted from the peer-to-peer-network (P2P1) to the peer-device (P1`) in the peer-to-peer network (P2P2) under information of the network address (IP1) of the peer-device (P1). Independent claims are also included for the following: (1) a peer-device for a peer-to-peer network (2) a network arrangement with a peer-to-peer-network with peer -devices.
