Abstract

A remote maintenance server includes a processor that operates as a remote panel function start instruction receiving unit that receives an instruction to start a remote panel function from a user via the user terminal and the user operation server, a relay server determining unit that determines the relay server to be used when executing the remote panel function, a verification information writing unit that writes verification information in the cache server, the verification information being used when the relay server relays connection, and a connection command sending unit that sends a connection command to the image forming apparatus that executes the remote panel function via the connection server, the connection command instructing to connect to the relay server to be used.

First claim

What is claimed is:

1. A remote management system, comprising:
a user operation server;
a remote maintenance server;
a connection server;
a relay server;
a cache server;
a user terminal; and
an image forming apparatus,
the user operation server, the remote maintenance server, the connection server, the relay server, and the cache server being connected to each other via a network,
the user terminal being connected to the user operation server, the remote maintenance server, the connection server, the relay server, and the cache server via Internet,
the image forming apparatus being connected to the user operation server, the remote maintenance server, the connection server, the relay server, and the cache server via the Internet,
the remote maintenance server including a processor that operates as
a remote panel function start instruction receiving unit that receives an instruction to start a remote panel function from a user via the user terminal and the user operation server,
a relay server determining unit that determines the relay server to be used when executing the remote panel function,
a verification information writing unit that writes verification information in the cache server, the verification information being used when the relay server relays connection, and
a connection command sending unit that sends a connection command to the image forming apparatus that executes the remote panel function via the connection server, the connection command instructing to connect to the relay server to be used,

the relay server including a processor that
relays connection from the user terminal that executes the remote panel function and connection from the image forming apparatus that executes the remote panel function on a basis of verification information stored in the cache server.

2. The remote management system according to claim 1 , further comprising:
a load distribution apparatus being one end point; and
a relay management server that manages the relay server,
the load distribution apparatus and the relay management server being connected between the Internet and the relay server,
the load distribution apparatus being connected between the Internet and the relay management server,
the relay management server being connected between the load distribution apparatus and the relay server.

3. The remote management system according to claim 2 , wherein
the load distribution apparatus, the relay management server, and the relay server are provided for every site out of multiple sites, and
the relay management server and the relay server in one site out of the multiple sites are connected to the relay management server and the relay server in another site out of the multiple sites via a network faster than Internet.

4. An information processing method for an remote management system including
a user operation server,
a remote maintenance server,
a connection server,
a relay server,
a cache server,
a user terminal, and
an image forming apparatus,
the user operation server, the remote maintenance server, the connection server, the relay server, and the cache server being connected to each other via a network,
the user terminal being connected to the user operation server, the remote maintenance server, the connection server, the relay server, and the cache server via Internet,
the image forming apparatus being connected to the user operation server, the remote maintenance server, the connection server, the relay server, and the cache server via the Internet,
the information processing method comprising:
by a remote panel function start instruction receiving unit of the remote maintenance server, receiving an instruction to start a remote panel function from a user via the user terminal and the user operation server;
by a relay server determining unit of the remote maintenance server, determining the relay server to be used when executing the remote panel function to connect the user terminal and the image forming apparatus;
by a verification information writing unit of the remote maintenance server, writing verification information in the cache server, the verification information being used when the relay server relays connection between the user terminal and the image forming apparatus by using the remote panel function;
by a connection command sending unit of the remote maintenance server, sending a connection command to the image forming apparatus that executes the remote panel function via the connection server, the connection command instructing to connect to the relay server determined;
by the image forming apparatus that executes the remote panel function, connecting to the relay server determined;
by the user terminal that executes the remote panel function, connecting to the relay server determined; and
by the relay server, connecting the image forming apparatus and the user terminal that executes the remote panel function by using the verification information in the cache server, and starting the remote panel function.

5. An information processing method for an remote management system including
a relay management server,
relay servers,
a user terminal, and
an image forming apparatus,
the relay management server, the relay servers, the user terminal, and the image forming apparatus being connected to each other via a network,
the information processing method comprising:
by a first connect receiving unit of the relay management server, receiving connection from the user terminal and the image forming apparatus to execute a remote panel function;
by a live confirmation unit of the relay management server, sending a “live confirmation” message to the relay servers, and checking whether or not the relay servers are capable of newly receiving transfer of connection;
by a connection volume confirmation unit of each of the relay servers, confirming whether or not a connection volume of the relay server reaches an upper limit,
by a live confirmation reply unit of each of the relay servers, sending, in reply to the “live confirmation” message sent from the relay management server, a “new request receivable” message or a “new request unreceivable” message on a basis of a confirmation result of the connection volume confirmation unit;
by the connection transferring unit of the relay management server, transferring the connection received by the first connect receiving unit to one relay server that returns the “new request receivable” message; and
by a second connect receiving unit of each of the relay servers, receiving the connection from the user terminal and the image forming apparatus, the connection being transferred from the relay management server.

6. The information processing method according to claim 5 , further comprising:
by a connection shifting unit of each of the relay servers, if the relay server is to be rebooted for system maintenance, shifting the currently managing connection to another relay server, in a unit so as not to affect performance of the relay management server;
by a reboot determining unit of each of the relay servers, determining whether or not it is necessary to reboot the relay server for the system maintenance; and
by a reboot unit of each of the relay servers, rebooting the relay server.

7. The information processing method according to claim 5 , further comprising:
by an automatic deploy unit of the relay management server, additionally and newly deploying a relay server, if all the relay servers return the “new request unreceivable” message in response to the “live confirmation” message from the live confirmation unit; and
by the connection transferring unit of the relay management server, transferring the connection received by the first connect receiv
