Connection switching method, device and system

Abstract

The invention discloses a connection switching method, device and system. According to the invention, when a client has data exchange with a service server through a first connection, a to-be-switched acceleration server is determined and a switching request with server mark information of the acceleration server is sent to the service server. A second connection with the service server is established through the acceleration service and data is sent to the acceleration server. The acceleration server adds the server mark information of itself to the data and sends the data to the service server. The service server performs data exchange with the client through the second connection when that the server mark information carried by the data and the server mark information carried by the switching request are identical is determined. Therefore, the client does not need to break the connection with the service server and connection switching can be realized during data exchange with the service server. The efficiency of data exchange between the client and the service server can be improved effectively.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a connection switching method, device and system. Background technique [0002] With the rapid development of computer technology and network technology, users can already conduct various businesses through the network. Generally, when performing business, a user can connect to a business server through a client to obtain business services provided by the business server. [0003] In practical applications, the client needs to connect to the business server through several network nodes (such as switches, etc.), and if the load of one of the network nodes is high, the connection speed between the client and the business server will be low , that is, the delay time from the client to the business server is relatively long. Therefore, in order to increase the connection speed between the client and the business server, in the prior art, when establishing a connection wit...

[0005] However, the delay time from the client to the business server and each acceleration server is not fixed, but varies with the network load (such as the load of each network node between the client and the business server, the network delay of each acceleration server). load conditions), therefore, in actual application scenarios, it is likely that the connection speed of the user to the business server through the acceleration server at a certain moment is relatively fast, but the connection speed is getting slower and slower during the connection process In this case, it is necessary for the client to determine in real time which acceleration server to connect to the business server through which the delay time is the smallest, or whether the delay time to directly connect to the business server is the smallest, and switch the connected acceleration server or business server according to the determined result

[0006] In the prior art, when a client is connected to a service server through an acceleration server, if it is to be switched to another acceleration server or directly to the service server, or, when the client is directly connected to the service server, if it is to be switched To connect to the business server through an acceleration server, you must first disconnect the connection with the currently connected acceleration server or business server, and then re-establish the connection, which will obviously reduce the efficiency of data interaction between the client and the business server
