Abstract: A method of storing semantically similar documents on proximally located peers in a structured peer to peer overlay network, where each peer is assigned a unique identifier and each document includes one or more words belonging to at least one hierarchical structured collection of words. A method of searching and retrieving documents, corresponding to a search query, from a structured peer to peer overlay network is also provided.

Abstract: A system, method, and computer program product for dynamically managing packet delay of a received packet of data between multiple endpoints, including a delay estimator module adapted to calculate packet delay of the received packet of data. The system further includes a predictor module adapted for predicting a playout time for each received packet of data indicative of the calculated packet delay of the at least one received packet of data. Furthermore, the system includes a buffer module adapted for buffering the received packet of data for a variable amount of time and a player module adapted for playing only the received packet of data and to discard packets of data received after the predicted playout time. The delay estimator is adapted to calculate maximum delay of all the packets of data received in an interval within a predetermined threshold indicative of the calculated packet delay.

Abstract: A gateway module is provided for connecting multiple networks. A connection set up module is provided. The connection set up module is configured to set up a transport layer connection between two correspondent nodes in first and second wire networks in divided forms of first and second connections. The first and second connections are in a transport layer protocol suitable for communications with correspondent nodes in the first and second wire networks. A control module controls the connection set up module by determining whether or not to carry out a connection set up by the connection set up module. The connection set up is made according to information content of a packet. The packet contains a transport layer protocol data unit, from a correspondent node in the second network, that requests a set up of the transport layer connection between the first and second networks.
