Terminal apparatus, relay apparatus, processing method, recording medium, and data signal

A method for a system including a terminal apparatus and a relay apparatus, the method comprising:

• a requesting process performed by the terminal apparatus;
• and
• a relay process performed by the relay apparatus,
• wherein the requesting process comprises:
• obtaining, using a first controller comprising a first central processing unit included in the terminal apparatus, a request for forming an image to be made to a processing execution apparatus that forms images;
• generating a relay-use processing request containing the obtained request for forming the image and address information of the processing execution apparatus;
• obtaining address information indicating the relay apparatus connected to each of a first communication path and a second communication path, the processing execution apparatus being connected to the first communication path, the terminal apparatus being connected to the second communication path;
• transmitting the generated relay-use processing request to the relay apparatus indicated by the obtained address information or transmitting the obtained request for forming the image to the processing execution apparatus connected to the first communication path;
• and
• judging, by the terminal apparatus, whether the terminal apparatus can be directly connected to the first communication path based on a first predetermined condition, the first predetermined condition comprising one or more of a level to which update patches have been applied to the terminal apparatus, a version of an operating system, and information regarding a version of a virus definition file,
• wherein in a case that the terminal apparatus is judged by the judging as not meeting the first predetermined condition, the transmitting comprises transmitting the generated relay-use processing request to the relay apparatus indicated by the obtained address information, and in a case that the terminal apparatus is judged by the judging as meeting the first predetermined condition, the transmitting comprises transmitting the obtained request for forming the image to the processing execution apparatus connected to the first communication path,
• wherein the relay process comprises:
• connecting, by a second controller comprising a second central processing unit included in the relay apparatus, the relay apparatus to the first communication path to which the processing execution apparatus is connected;
• connecting, by the second central processing unit, the relay apparatus to the second communication path to which the terminal apparatus is connected, the second communication path being logically isolated from the first communication path;
• receiving the relay-use processing request containing the request for forming the image from the terminal apparatus via the second communication path;
• determining whether or not the received relay-use processing request containing the request for forming the image meets a second predetermined condition even if the terminal apparatus is judged as not meeting the first predetermined condition;
• and
• transmitting the relay-use processing request containing the request for forming the image that is determined as meeting the second predetermined condition to the processing execution apparatus via the first communication path.

A non-transitory computer-readable recording medium storing a program causing a system including a terminal apparatus and a relay apparatus to execute a process, the process comprising:

• a requesting process performed by the terminal apparatus;
• and
• a relay process performed by the relay apparatus,
• wherein the requesting process comprises:
• obtaining a request for forming an image to be made to a processing execution apparatus that forms images;
• generating a relay-use processing request containing the obtained request for forming the image and address information of the processing execution apparatus;
• obtaining address information indicating the relay apparatus connected to each of a first communication path and a second communication path, the processing execution apparatus being connected to the first communication path, the terminal apparatus being connected to the second communication path;
• transmitting the generated relay-use processing request to the relay apparatus indicated by the obtained address information or transmitting the obtained request for forming the image to the processing execution apparatus connected to the first communication path;
• and
• judging, by the terminal apparatus, whether the terminal apparatus can be directly connected to the first communication path based on a first predetermined condition, the first predetermined condition comprising one or more of a level to which update patches have been applied to the terminal apparatus, a version of an operating system, and information regarding a version of a virus definition file,
• wherein in a case that the terminal apparatus is judged by the judging as not meeting the first predetermined condition, the transmitting comprises transmitting the generated relay-use processing request to the relay apparatus indicated by the obtained address information, and in a case that the terminal apparatus is judged by the judging as meeting the first predetermined condition, the transmitting comprises transmitting the obtained request for forming the image to the processing execution apparatus connected to the first communication path,
• wherein the relay process comprises:
• connecting the relay apparatus to the first communication path to which the processing execution apparatus is connected;
• connecting the relay apparatus to the second communication path to which the terminal apparatus is connected, the second communication path being logically isolated from the first communication path;
• receiving the relay-use processing request containing the request for forming the image from the terminal apparatus via the second communication path;
• determining whether or not the received relay-use processing request containing the request for forming the image meets a second predetermined condition even if the terminal apparatus is judged as not meeting the first predetermined condition;
• and
• transmitting the relay-use processing request containing the request for forming the image that is determined as meeting the second predetermined condition to the processing execution apparatus via the first communication path.
