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.

摘要： A caching method for caching network contents of a packet transfer network including a packet relay for relaying accesses of clients to servers supplying contents, and a network contents cache device are disclosed. Accesses from the clients to the servers are monitored by the said packet relay to determine a cache priority on the basis of a product of relaying path lengths from the packet relay to the server and frequency of access from the client to the servers and the network contents cache device preferentially caches a response to the access to the server having higher cache priority.

摘要： A fast reservation protocol type ATM switching method and ATM switching equipment which are capable to suppress deterioration in transmission efficiency by reducing a cell discarding rate even in case of transmitting a huge ATM cell burst is provided. A buffer monitoring circuit monitors the number of idle slots in a buffer of an ATM switching equipment. A resource management (RM) cell processing circuit compares the number of idle slots with the total number of cells consisting an ATM cell burst contained in an RM cell locating at the top of the ATM cell burst stream when receiving the ATM cell burst from an ATM subscriber equipment. If the number of idle slots is not available for storing all cells in the ATM cell burst, the RM cell processing circuit instructs a gate circuit to pass same number of cells as idle slots available in the buffer and discard the rest of cells, and transmits a RM cell, containing information of number of cells to be retransmitted, to the ATM subscriber equipment for requesting retransmission.

摘要： A transmitter/receiver 101 on a mobile body 10 utilizes a plurality of antennas 100. It is assumed that a plurality of the antennas 100 are distributed and arranged in a moving direction of the mobile body, and the antennas at both ends are away from each other at an extent that a distance between the antennas is not negligible as compared with an interval of the base station. A radio wave from the base station 102-1 is stronger in intensity in 100-1 than in the center, and the radio wave from the base station 102-2 is stronger in intensity in 100-2 than in the center, respectively, whereby the communication stabilization effect, which is larger as compared with the case that the antennas are locally located in the center, is expected. This enables the interval of the base station, which is broader than the conventional one, to be employed, yet both of a speed and a frequency of a hand-over process to be lowered, and in addition hereto, the bandwidth utilization efficiency, which is higher as compared with that of the conventional example, to be realized.

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： 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.
