摘要:
Provided are an information processing system, a tunnel communication device, a tunnel communication method, and a program that can make a communication between plural information processing devices belonging to different LANs without a user's making a complex setup. In the information processing system, a first tunnel communication unit encapsulates a packet from a first information processing device, transmits the encapsulated packet through a path of a P2P communication, and decapsulates the packet transmitted from a second tunnel communication device through the path of the P2P communication. A second tunnel communication unit encapsulates the packet transmitted from the second information processing device, transmits the encapsulated packet through the path of the P2P communication, and decapsulates the packet transmitted from the first tunnel communication device through the path of the P2P communication.

Provided is an information processing system and the like that can make a communication between plural information processing devices belonging to different LANs. A first tunnel communication device includes a first address correlating information memory unit that stores information for correlating an address in a first LAN with an address in a second LAN, a first address translating unit that translates an address of a packet on the basis of the correlating information, a first P2P communication setup unit that sets up a P2P communication with a device as a destination, and a first tunnel communication unit that makes a tunnel communication through a path of a P2P communication. The packet transmitted from a first information processing device is translated in address, is encapsulated, and is then transmitted through the path of the P2P communication. The packet transmitted from the device as a destination is decapsulated, is translated in address, and is then transmitted to the first information processing device.

An information processing device 1 includes a transmission judging section 11 for judging whether to transmit a repetition packet, a life judging section 12 for judging whether to set a life not reaching a server device 3 to the repetition packet, a life setting section 14 for setting the life of the repetition packet to the life not reaching the server device 3 when the life judging section 12 judges to set the life not reaching the server device 3, and setting the life of the repetition packet to the life reaching the server device 3 when the life judging section 12 judges to set the life reaching the server device, and a transmitting section 15 for transmitting a repetition packet having the life set by the life setting section 14, when the transmission judging section 11 judges to transmit the repetition packet. It is possible to reduce a processing burden on the server device in an information processing system provided with the information processing device for repetitively transmitting the packet and the server device for receiving the packet.

A first information processor transmits a bubble packet to a port assigned after assignment of specified port from reference port in a second communication control unit, a server detects the position of the bubble packet transmitting port in a first communication control unit used in transmission of this bubble packet, and a second information processor transmits a reply packet to the detected bubble port transmitting port. In this configuration, the invention presents a communication system capable of establishing more securely communication between plural information processors for communicating by way of communication control unit (NAT). In this configuration, the invention presents a communication system capable of establishing more securely communication between plural information processors for communicating by way of communication control unit (NAT).

An information processor (1) comprises: a history packet transmitter (11) for transmitting a history packet; a request packet transmitter (12) for transmitting a request packet requesting transmission of a return packet; a packet transmission controller (13) for controlling transmission of a request packet by using a binary search method; a return packet receiver (14) for receiving a return packet transmitted from a server (3); and a port keeping time detector (15) for detecting the port keeping time of a communication processor (2) based on reception of a return packet by the return packet receiver (14). The server (3) includes: a request packet receiver (31) for receiving a request packet; and a return packet transmitter (32) for transmitting a return packet to a port of the communication processor (2) where a history packet passed when the request packet receiver (31) received a request packet. This configuration provides an information processing system for detecting the port keeping time of the communication processor.

A connection server (3) has a receiving part (31) for receiving request information regarding a request for load sharing, which is sent from a first information processing apparatus (1) to a load sharing port of the connection server (3), a load sharing part (32) for allocating the first information processing apparatus (1) that is a source of the request information to any processing server, a sending part (33) for sending port position information indicating the position of the connection port corresponding to the allocated processing server to the first information processing apparatus (1), and a connection part (34) for establishing a connection between the connection port and the processing server corresponding to the connection port. The first information processing apparatus (1) sends the received port position information to a second information processing apparatus (2). With this configuration, in a communication system for load sharing, two or more information processing apparatuses have access to one processing server.
