(57) Abstract :
The invention deals with the problem of allowing a peer-to-peer network using chord topology, in which some of the nodes have
access protection which allows reception of messages only from those network addresses to which a message has previously been sent
A network such as this is dependent on each node maintaining a list with further nodes, referred to in general as a finger list. In order
to allow communication despite access protection, each node sends a request at fixed time intervals to the nodes in its list, to send it a
message. This makes it possible for each node to send messages to the nodes in its list. A search request for a file is passed on via
intermediate nodes in the network such that the searching node is provided with access to a destination node which can offer the file,
and the access protection of the destination node is cancelled.FIG 2
