US 2011/0238835 A1 · RELAY SERVER AND RELAY COMMUNICATION SYSTEM ARRANGED TO SHARE RESOURCES BETWEEN NETWORKS

Abstract

A relay server which is connected to a LAN and which can communicate with a relay server in a different LAN, includes: an account information registering unit that stores information on client terminals connected to the LAN; a relay group information registering unit that stores relay group information; a shared resource information registering unit that stores shared resource information; a check unit that checks whether the client terminals stored in the account information registering unit can be accessed; a relay group information notifying unit that updates the relay group information and transmits a change notification of the relay group information to the relevant relay server; and a shared resource information notifying unit that updates the relevant shared resource information and transmits a change notification of the shared resource information to the relevant client terminal which is stored in the account information registering unit.

Claims6

Dependent claims

A relay server which is connected to a LAN and which can communicate via a WAN with at least one different relay server connected to a different LAN, the relay server comprising:

an account information registering unit that stores information about client terminals connected to the LAN to which the relay server is connected;
and
a relay group information registering unit that stores relay group information including information about a group of relay servers which includes the relay server and the at least one different relay server and permits access to each other, and information on the client terminals registered in the respective relay servers;
a control unit that, when receiving a connection request from a client terminal, determines whether the client terminal which transmitted the connection request has been registered in the account information registering unit, and, when the client terminal which transmitted the connection request has not been registered in the account information registering unit, identifies a different relay server of the at least one different relay server in which the client terminal which transmitted the connection request has been registered based on the relay group information, and determines whether to permit the connection while inquiring of the identified relay server.

1 more element

A management method using a relay server which is connected to a LAN and which can communicate via a WAN with at least one different relay server connected to a different LAN, the management method comprising:

storing account information about client terminals connected to the LAN to which the relay server is connected;
and
storing relay group information including information about a group of relay servers which includes the relay server and the at least one different relay server and permits access to each other, and information about the client terminals registered in the respective relay servers;
and
when receiving a connection request from a client terminal, determining whether information about the client terminal which transmitted the connection request has been stored in the step of storing account information, and, when information about the client terminal which transmitted the connection request has not been stored in the step of storing account information, identifying a different relay server of the at least one different relay server in which information about the client terminal which transmitted the connection request has been stored based on the relay group information, and determining whether to permit the connection while inquiring of the identified relay server.
