Embodiment 1

[0018] Such as figure 1 Shown is a server connection switching method according to an embodiment of the present invention. Through this method, on the one hand, normal switching of services can be realized, and on the other hand, redundancy of the business system can be realized, thereby realizing high availability of the system. The method comprises the following steps: receiving a connection request sent by a front-end server, establishing a long connection with the front-end server through the network according to the connection request (step S101); Interactive back-end server, and establish long connection (step S102) with described back-end server through network; Back-end server change request (step S103); according to the back-end server change request, within the time period from the change start time to the service flow retention time, send the front-end server to the transaction request of the change server The packet is forwarded to other back-end servers re-determ...

Embodiment 2

[0022] Such as image 3 As shown, it is a server connection switching device according to an embodiment of the present invention. The device includes: a connection request receiving unit 101, configured to receive a connection request sent by a front-end server, and establish a long-term connection with the front-end server through the network according to the connection request. connection; the load balancing unit 102 is used to determine the back-end server capable of data interaction with the front-end server through a load-balancing algorithm, and establish a long connection with the back-end server through the network; the change request receiving unit 103 uses After receiving the back-end server change request from the outside including the change section identifier, change start time, service flow retention time and change end time; the connection control unit 104 is configured to, according to the back-end server change request, During the time period from the change s...

Embodiment 3

[0033] like Image 6 Shown is the server connection automatic switching system of this embodiment, the system includes front-end servers 01, 02, LAN switches 03, 04, server connection switching devices 05, 06, and back-end servers 07, 08. Wherein, the front-end server 01 is connected to the Ethernet port 401 of the LAN switch 04 , and the front-end server 02 is connected to the Ethernet port 301 of the LAN switch 03 . The backend server 07 and the backend server 08 are respectively connected to the Ethernet port 302 of the LAN switch 03 and the Ethernet port 402 of the switch 04 . The Ethernet port 501 of the server connection switching device 05 is interconnected with the Ethernet port 403 of the LAN switch 04 . The Ethernet port 601 of the server connection switching device 06 is interconnected with the Ethernet port 303 of the LAN switch 03 . At the same time, the LAN switch 03 and the LAN switch 04 are interconnected through the Ethernet port 304 and the Ethernet port 40...

Abstract

The invention provides a method, a device and a system for connecting and switching a server. The method comprises the following steps: receiving a connection request sent by a front-end server, and establishing a long connection with the front-end server according to the connection request; according to a load balancing algorithm, determining a rear-end server which can interact data with the front-end server, and establishing the long connection with the rear-end server; receiving a rear-end server changing request transmitted from outside; according to the rear-end server changing request, during the period from a change starting time to a service stream holding time, forwarding a trading request packet which is sent to a change server by the front-end server to other rear-end servers re-determined by the load balancing algorithm, and sending a return packet which is fed back to the front-end server by the change server to the front-end server; and during the period from the service stream holding time to a change ending time, stopping communication with the change server. The method, the device and the system allow a trade which is being carried out by a client to be normally carried out when one end server is stopped to be maintained or switched.

Description

technical field [0001] The present invention relates to the technical field of computer application systems, and specifically relates to a server connection switching method, device and system. Background technique [0002] At present, the number and grade of various servers deployed by enterprises are increasing with the development of computer applications. Whether the entire computer application system of an enterprise operates safely, reliably and efficiently will directly test the operation management level and technical capabilities of the enterprise. For this reason, most enterprises adopt high-availability redundant design to achieve the purpose of healthy system operation. [0003] On the other hand, computer application systems generally use long or short connections for business system interaction. As a long-term connection, because it has the characteristics of continuously sending multiple data packets on one TCP connection, most enterprises, especially the fi...
