Embodiment 1

[0039] figure 2It is a schematic flowchart of a service switching method in a local area network according to an embodiment of the present invention, see figure 2 , the service switching method in the local area network of the present embodiment includes the following steps:

[0040] Step S201, preloading the server program for executing the service on at least two client devices in the local area network respectively, monitoring the running status of the server program on the client device, and determining the server program on the client device currently executing the service whether the program is functioning properly;

[0041] Step S202, when it is determined that the server program on the client device currently executing the service is running abnormally, switch the client device executing the service, and the client device running normally in the local area network starts the server on the client device program to execute the service.

[0042] Depend on figure 2 ...

Embodiment 2

[0048] In this embodiment, the implementation process of cloud-controlled service switching is mainly described, and other contents refer to other embodiments of the present invention.

[0049] image 3 It is a local area network network topology diagram of a service switching method in a local area network according to an embodiment of the present invention, see image 3 , in the local area network of this embodiment, there are four client devices in total, namely: client device A, client device B, client device C and client device D, each client device is installed with a client program (such as image 3 The "client" shown) and the server program ( image 3 "Service" as shown), that is, each client device can act as both a client and a server.

[0050] Note: the number of client devices in the local area network of this embodiment is four, and the server program is all loaded on each client device, but, in other embodiments of the present invention, also can be in four cl...

Embodiment 3

[0063] In this embodiment, the realization process of local contention service switching is mainly described, and other contents refer to other embodiments of the present invention.

[0064] Figure 5 It is a local area network network topology diagram of a service switching method in a local area network according to another embodiment of the present invention. In this embodiment, the local area network includes four client devices, namely: client device A, client device B, client device End device C, client device D, each client device is installed with a client program, for example, such as Figure 5 Client A and service A are loaded on the client device A shown in , and so on.

[0065] The local area network also includes a local database. The server program of the client device currently executing the service writes data to the local database regularly, while the server programs of other client devices read data from the local database regularly. In this way, when the lo...

Abstract

The invention discloses a service switching method, device and system for a local area network. The method comprises the steps of: previously loading a server program executing a service to at least two client devices in the local area network respectively, monitoring the running state of the server program on the client devices, and determining whether the server program on the client device executing the service currently runs normally; when determining that the server program on the client device executing the service currently runs abnormally, switching the client device executing the service, and starting, by the client device running normally in the local area network, the server program on the client device to execute the service. According to the technical solution, the server program executing a service is loaded to the at least two client devices in the local area network respectively and the service is dynamically switched, so that normal running of the service is ensured and the service is not influenced by failure of a single server. Besides, expensive server equipment does not need to be purchased, so that the capital input is reduced.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to a service switching method, device and system in a local area network. Background technique [0002] A local area network refers to a computer group composed of multiple computers interconnected in a certain area. figure 1 It is a schematic diagram of the network architecture of the local area network in the prior art, see figure 1 , in the prior art, the network structure of the local area network is usually a client / server model, that is, it includes multiple clients and a server, multiple clients are connected to the server, and the client and server software are installed on the local area network, generally a The server program in the local area network is installed on the server, the client software is installed on multiple client computers, the client software communicates with the server software, and then the server software communicates with the cloud.
