Problems solved by technology

However, since data packets pass through a VPN device, etc., when deleting and moving resources between multiple LANs, it is not easy to grasp information such as deletion and movement from the entire virtual network.

no. 1 Embodiment approach }

[0070]

[0071] Next, a first embodiment will be described with reference to the drawings. FIG. 1 is a diagram illustrating an example of the overall configuration of a relay communication system according to the present embodiment. As shown in FIG. 1, this relay communication system is composed of a plurality of LANs connected to a WAN. Furthermore, this relay communication system has an external server S, a relay server R, a client terminal T, a file server F, and the like. In addition, although the embodiment using the external server S was exemplified here, a system in which relay servers R directly communicate without using the external server S may also be used.

[0072]In this embodiment, the communication protocol between the external server S in the WAN and each relay server R, and between the relay server R in the LAN and the client terminal T, etc., is described by way of example. SIP (Session Initiation Protocol: Session Initiation Protocol) system. However, a...

[0185]

[0186] Next, a second embodiment will be described. Compared with the first embodiment, this embodiment has the same configuration of the relay communication system, external server S, relay server R, and file server F, but the configuration of the client terminal T is different.

[0187] FIG. 19 shows a functional block diagram of the client terminal T. As shown in FIG. The client terminal T of the present embodiment includes a display unit 605 in addition to the constituent elements of the client terminal T of the first embodiment. The display unit 605 displays the relay group information 100 shown in FIG. 20 and the like, and the shared resource information 120 shown in FIG. 21 and the like.

[0188]

[0189] Next, the processing flow of the client terminal T in this relay communication system will be described with reference to the flow charts in FIG. 22 and FIG. 23 . In addition, the relay group information 100 shown in FIG. 20 and the shared resource infor...

[0222] Next, a third embodiment will be described. Compared with the second embodiment, this embodiment has the same configuration of the relay communication system, external server S, client terminal T, and file server F, but the configuration of the relay server R is different.

[0223]FIG. 26 shows a functional block diagram of the relay server R. As shown in FIG. The relay server R of the present embodiment has a log information database (DB) 507 in addition to the constituent elements of the relay server R of the second embodiment. The log information DB 507 is a database that manages resource operation content relayed by each relay server R as log information.

Abstract

The present invention provides a relay server, a relay communication system, and a communication device. The relay communication system has good scalability and flexibility. In the relay communication system, between terminals of different LANs, when necessary When necessary, resources can be shared and operated with the other party. This relay communication system has a relay server (R) capable of communicating with a relay server (R) of another LAN via an external server (S) on the WAN. The relay server (R) saves the account information including the client terminal (T) in the LAN, the relay group information (100) of a group of relay servers (R), the resource and the account of the client terminal (T) sharing the resource shared resource information (120). When the relay server (R) receives an operation instruction from a client terminal (T) in a LAN to a resource held by a client terminal (T) in another LAN, it performs the relay group information (100) and shared resource information ( 120), relaying the operation on the resource.

Description

technical field [0001] The present invention relates to a relay server and a relay communication system capable of communicating with a terminal in another local area network (LAN) across a wide area network (WAN). In particular, it relates to a technique for operating resources held by terminals in another LAN from a terminal in a certain LAN. Background technique [0002] There is a communication technology called VPN (Virtual Private Network: Virtual Private Network). Using this communication technology, it is possible to use other LANs that are far apart like a directly connected network. For example, it is possible to communicate across the Internet between terminals connected to LANs of a plurality of branch offices installed in various regions. [0003] Regarding this technique, various systems have been proposed so far (for example, Japanese Patent Laid-Open No. 2002-217938). [0004] However, such a system tends to become a rigid system due to the relationship of...
