The preferred embodiment of the server cluster system of the virtual office of the present invention is applied to a virtual office. Please refer to FIG. 3 for a block diagram of the system of the present invention, which shows that the system of the present invention includes a client, a server, and a server. Terminal 20, and a database 30. The client 10 can perform the service of accessing data; the server 20 forms a server cluster for the client 10 to connect through the network 90 and send out its needs for access operations. Each temple server 20 The system uses a designed communication protocol (pr0c01) to divide labor and service the client 10; while maintaining the consistency of data, it is left to the database 30 for management, and the database 30 is used In order to store all the data accessed in the cluster, it is not necessary to require each server 20 to store the same data, so as to reduce the waste of storage space. Different from the conventional design, the present invention will design the function of the guide server 80 as shown in FIG. 2 and FIG. 2 as a module and incorporate it into each server 20. In this embodiment, the functions of the server 20 can be divided into two categories, one is to provide the client 10 service, and the other is to communicate with the other server 20. Please refer to FIG. 4 for the architecture diagram of the server and client of the present invention, which shows that the server 20 includes six modules, and the client 10 includes three modules.

Description of the invention (<) Introduce the function of each module in each-server 20. The connection monitoring module 21 (CClientLiStenDaem0n) is responsible for receiving the connection (Accept Socket) of the client lo, and transmitting the received connection to the monitoring module 22 (CClientDaemon), in order to facilitate its authentication action. The virtual office module 23 (CoficeRoom) is used to simulate the office of an ordinary person. It will have the services required for daily office work, such as modifying the documents written to -50 yesterday, or submitting to the planning office. You can go to the first office for documents and other services. If you want to talk with other colleagues by voice, you can add a second office to talk to them. Or you can go to the third office to receive training courses and other services. The above services are provided in this embodiment, and f can be obtained through the virtual office module 1 23, wherein the virtual office module 23 can process services such as general documents, voice, or image data. After the client 10 completes the initial connection, it will issue a request to open or join a virtual office module 23, and the office management module 24 (CR〇〇mManage〇 is based on the client 1〇 Request to open, add, replace, or delete the virtual office module 23. The services that the client 10 can obtain through the virtual office module 23 are listed in service module 25 (C Service s) ), In this example, because in a server cluster system, the services provided by each server 20 are different (some specialize in providing voice services, some specialize in providing image services, etc.), so Each server 200 maintains a list of services, which stores information about all services on the server 20. The service module 2 5 is responsible for the registration and query of these services. When a virtual office module 2 3 542966 Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 V. When the client 10 in the description of invention (b) wants to use a specific service, he can query through this list to obtain the required service Since the servo cluster system is composed of multiple server terminals 20, a cluster channel module 26 (cciuseterchannel) must be used to communicate with other server terminals 20. In addition, when there is a new server terminal 2 To be added to the cluster system, the cluster channel module 26 is also used to communicate with other servers 20. In addition, the monitoring module 22 will continue to communicate with the client 10 until the client 10 reaches one of the virtual office modules The service is executed in 23. If the load on server 20 is too heavy, the client 10 received by the monitoring module 22 will be converted to other server 20 through cluster channel module 26 to perform the access operation. Introduce the functions of each module in each client 10. The document file service module 11 (CDataService) is used to obtain general documentary services, mainly used to send each other's files or messages; the voice service module 12 ( CV〇iceSerVice) is used to obtain voice services, including voice compression and decompression services, of course, it can also handle 丨 〇 丨 "

The client 10 connects to the server 20, requests to join the office, sends a service request to the server 20, and after the identity is verified by the monitoring module 22, the office management Module μ adds the client 1G to the virtual office module 23, and the client in the virtual office module 23 queries the service module 25 for the services provided by the cluster system. These services include uploading or downloading data by client 1G, or holding talks with other client 10. If it is confirmed to be correct, the client 10 can obtain the service it requested. Next, please see the right half of Figure 5. A new server 20 is displayed. Through its cluster channel module 26, it is connected to the cluster channel module 26 of the server 20, and forwards to the server 20. The service module 25 registers and informs the service it owns so that the service module 25 can provide it to the client 10 for use. In this example, UML is used to define the content of each module, where each module can be regarded as an object in UML, and the module naming method refers to the naming rule of Microsoft programming, and uses C ++ as the The programming language is not limited in practical application. Please refer to FIG. 6 and FIG. 7 ′, which are UML object diagrams of the server 20 and the client 10 in this embodiment. The CCluster in Figure 6 is regarded as the server 2 itself, which can coordinate the four objects of CClusterChannel, CClientDaemon, CServices, and CRoomManager. It can use CC 1 uster C ha η ne 1 to communicate with other server 2 0.
