摘要： A network server includes LAN terminating units, an ATM terminating unit, a data transfer unit, a multiple identifier check section, and a connection determination section. The LAN terminating units are connected to LAN terminals constituting virtual LAN segments and terminate protocols on the LAN MAC sublayer. The ATM terminating unit is connected to an ATM network and terminates the AAL and the ATM protocol. The data transfer unit transfers received data to one of the LAN terminating units and the ATM terminating unit in correspondence with the destination MAC address obtained from data received by the LAN terminating units and the ATM terminating unit. The multiple identifier check section checks at least the Ethernet type in the SNAP of the received data. When the data is transferred from the data transfer unit to the ATM terminating unit, the connection determination section determines an ATM connection to which the data is to be transmitted, on the basis of a set of the destination MAC address and the destination IP subnetwork address, obtained from the received data, and an identifier including at least the Ethernet type detected by the multiple identifier check section, and notifies the ATM terminating unit of the determined ATM connection.

摘要： When a packet transfer equipment receives a packet, it extracts several types of information contained in the received packet such as the destination IP address and the destination port number and, using the extracted information as the key, inquires of a packet transfer method resolution server about the information related to the packet transfer method. The server keeps the correspondences between several types of information contained in the packet and one or more type of information related to the packet transfer method in the database and, in response to the inquiry from the packet transfer equipment, replies one or more type of information related to the packet transfer method. The packet transfer equipment rewrites several types of information such as the destination IP address and the destination port number according to one or more type of information obtained and transfers the received packet.

摘要： A VPN connection method and a communication system are provided, each which can omit the setting of a firewall and the installation of a relay server and can establish communications from the outside of a firewall to the inside thereof. The internal network 2 is connected to the external network 1 via the firewall 13. The internal network 2 enables communications by an e-mail from the external network 1 (outside the firewall) to the mail server 21 in the internal network 2 (inside the firewall) or communications by telephone or radio, which is not via the firewall 3. The feature of the firewall 3 is utilized that access from the outside to the inside of the firewall through VPN connection is very difficult but the access in the reverse stream can be simply performed. Using the mail server, telephone line or radio line, the internal network 2 receives an e-mail, which requires for VPN connection from the external network 1, or control information through the telephone line. Thus, the internal network 2 sends callback for VPN connection to the e-mail transmission source. As a result, the callback allows the external network 1 to pass through the firewall 3.

摘要： To obtain a content distribution system in which the load placed on a distribution server is reduced, the installation cost and the operational cost are reduced, introduction can be easily realized in a large area, and clients only wait short periods for playing back. A distribution server device converts a content into stream data using an algorithm of near video on demand, and transmits the stream data to an end-system multicast tree established among plural client devices requesting playback of the content. The client devices relay the received stream data of the near video on demand in accordance with the end-system multicast tree.

摘要： A method for transferring a series of layer-3 packets through an ATM network composed of a plurality of ATM switches is disclosed. An ingress gateway determines whether a packet flow has been registered and, when the flow has not been registered, determines a transfer route. A connection setup cell is transmitted to a next-hop ATM switch to ensure a connection dedicated to transfer of tho series of packets. Then, a series of packets is transferred to the next-hop ATM switch through the connection after the connection has been set up.
