Image processing system, relay server, and program for relaying communications

摘要

An image processing system includes: an application server located in the Internet; an image processing apparatus located in a local network connected to the Internet via a firewall; a relay server configured to relay communication between the image processing apparatus and the application server, the relay server being located in the local network; and a connection mediation server configured to transmit, to the relay server, a request for a connection to the application server, the connection mediation server being located in the Internet, wherein the connection mediation server includes a connection request transmitting unit so as to have communication established between the image processing apparatus and the application server, the relay server includes: a communication establishing unit; a job transferring unit; a job identifying unit; and a communication terminating unit, and after the communication terminating unit terminates the communication, the communication establishing unit reestablishes the communication.

主权项

1. An image processing system comprising:
an application server connected to the Internet; an image processing apparatus connected to a local network, wherein the local network is connected to the Internet via a firewall; a relay server that relays communication between the image processing apparatus and the application server, wherein the relay server is connected to the local network; and a connection mediation server that transmits, to the relay server, a request for a connection to the application server, wherein the connection mediation server is connected to the Internet, wherein the connection mediation server comprises a connection request transmitting unit that transmits a connection request to the relay server in response to receiving a communication start request from the application server, and the communication start request designates the image processing apparatus to establish communication between the image processing apparatus and the application server, the relay server comprises:
a communication establishing unit that establishes the communication by connecting to the application server based on the connection request from the connection mediation server;a job transferring unit that transfers a job received from the application server to the image processing apparatus;a job identifying unit that identifies a type of the job; anda communication terminating unit that terminates the communication based on the type of the job identified by the job identifying unit, andafter the communication terminating unit terminates the communication, the communication establishing unit reestablishes the communication by connecting to the application server after receiving data to be transmitted to the application server from the image processing apparatus, and transfers the data.
