Information Processing Apparatus and Information Processing Method

Content Provider	The Lens
Abstract	An information processing apparatus is provided that includes an operation unit implemented by an information processing terminal connected via a communication line. The information processing apparatus includes a memory storing a program and a processor configured to execute the program to implement processes of opening a port for receiving a packet conforming to a predetermined communication protocol in response to a request from the information processing terminal, and transmitting data included in the packet to the information processing terminal in response to receiving the packet that is directed to the port.

Claim	An information processing apparatus including an operation unit that is implemented by an information processing terminal connected via a communication line, the information processing apparatus comprising: a memory storing a program; and a processor configured to execute the program to implement processes of opening a port for receiving a packet conforming to a predetermined communication protocol in response to a request from the information processing terminal; receiving an asynchronous event reception setting request to enable transmission of the packet to be transmitted to the information processing terminal upon receipt of the packet; and transmitting data included in the packet to the information processing terminal in response to receiving the packet that is directed to the port, wherein the request from the information processing terminal includes a relay condition for the packet, and the processor transmits the data included in the packet to the information processing terminal if the packet satisfies the relay condition, the relay condition being satisfied in a case where a transmission source IP address is specified from which a packet relay is permitted, a transmission source port number is specified from which the packet relay is allowed, or a predetermined value is included at a predetermined position of the data included in the packet. The information processing apparatus according to claim 1 , wherein the processor receives a plurality of requests for opening a plurality of ports from the information processing terminal, each request designating a port number of the port to be opened; the processor opens the port identified by the port number designated in each request in response to receiving the each request from the information processing terminal; and upon receiving a packet directed to one port of the plurality of ports, the processor transmits the port number of the one port and the data included in the packet to the information processing termina The information processing apparatus according to claim 1 , wherein the processor further implements a process of closing the port in response to a close request from the information processing termina The information processing apparatus according to claim 1 , wherein the predetermined communication protocol corresponds to UDP (User Datagram Protocol). The information processing apparatus according to claim 3 , wherein upon completion of the port closing process, the information processing terminal designates the port number of the closed port, and transmits a request to the information processing apparatus to cancel the asynchronous event reception setting. An information processing method executed by an information processing apparatus including an operation unit that is implemented by an information processing terminal connected via a communication line, the information processing method comprising: opening a port for receiving a packet conforming to a predetermined communication protocol in response to a request from the information processing terminal; receiving an asynchronous event reception setting request to enable transmission of the packet to be transmitted to the information processing terminal upon receipt of the packet; and transmitting data included in the packet to the information processing terminal in response to receiving the packet that is directed to the port, wherein the request from the information processing terminal includes a relay condition for the packet, and the processor transmits the data included in the packet to the information processing terminal if the packet satisfies the relay condition, the relay condition being satisfied in a case where a transmission source IP address is specified from which a packet relay is permitted, a transmission source port number is specified from which the packet relay is allowed, or a predetermined value is included at a predetermined position of the data included in the packet. The information processing method according to claim 6 , further comprising: receiving a plurality of requests for opening a plurality of ports from the information processing terminal, each request designating a port number of the port to be opened; opening the port identified by the port number designated in each request in response to receiving the each request from the information processing terminal; and upon receiving a packet directed to one port of the plurality of ports, transmitting the port number of the one port and the data included in the packet to the information processing termina The information processing method according to claim 6 , further comprising: closing the port in response to a close request from the information processing termina The information processing method according to claim 6 , wherein the predetermined communication protocol corresponds to UDP (User Datagram Protocol). The information processing method according to claim 8 , wherein upon completion of closing the port, the information processing terminal executes processes of designating the port number of the closed port, and transmitting a request to the information processing apparatus to cancel the asynchronous event reception setting. A non-transitory computer program product, including computer-executable instructions to be executed by an information processing apparatus including an operation unit that is implemented by an information processing terminal connected via a communication line, the computer-executable instructions, when executed, causing the information processing apparatus to implement processes of: opening a port for receiving a packet conforming to a predetermined communication protocol in response to a request from the information processing terminal; receiving an asynchronous event reception setting request to enable transmission of the packet to be transmitted to the information processing terminal upon receipt of the packet; and transmitting data included in the packet to the information processing terminal in response to receiving the packet that is directed to the port, wherein the request from the information processing terminal includes a relay condition for the packet, and the processor transmits the data included in the packet to the information processing terminal if the packet satisfies the relay condition, the relay condition being satisfied in a case where a transmission source IP address is specified from which a packet relay is permitted, a transmission source port number is specified from which the packet relay is allowed, or a predetermined value is included at a predetermined position of the data included in the packet. The non-transitory computer program product according to claim 11 , wherein the computer-executable instructions further causes the information processing apparatus to implement processes of receiving a plurality of requests for opening a plurality of ports from the information processing terminal, each request designating a port number of the port to be opened; opening the port identified by the port number designated in each request in response to receiving the each request from the information processing terminal; and upon receiving a packet directed to one port of the plurality of ports, transmitting the port number of the one port and the data included in the packet to the information processing termina The non-transitory computer program product according to claim 11 , wherein the computer-executable instructions further causes the information processing apparatus to implement a process of closing the port in response to a close request from the information processing termina The non-transitory computer program product according to claim 11 , wherein the predetermined communication protocol corresponds to UDP (User Datagram Protocol). The non-transitory computer program product according to claim 13 , wherein upon completion of the port closing process, the information processing terminal designates the port number of the closed port, and transmits a request to the information processing apparatus to cancel the asynchronous event reception setting.
