Embodiment Construction

[0036] The basic idea of ​​the present invention is: the user terminal sends a request message to the load balancing device, the load balancing device selects a suitable server, and migrates the request message of the user terminal to the selected server; the server sends a request message to the user terminal After processing, the response message is sent directly to the user terminal.

[0037] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments.

[0038] Such as figure 1 As shown, the TCP connection migration system of the present invention includes a user terminal 11, a load balancing device 12, and a server 13; among them,

[0039] The user terminal 11 is configured to send a content request message to the load balancing device 12;

[0040] The load balancing device 12 is configured to receive a request from the user terminal 11, select a server 13 from the server cluster, and migrate the connection of the user ...

Abstract

The invention discloses a transmission control protocol (TCP) connection migratory method, which comprises the following steps of: a user terminal sends a request message to load balancing equipment; the load balancing equipment selects a server and migrates the request message of the user terminal to the selected server; and after the server processes the request message of the user terminal, the server directly sends a response message to the user terminal. The invention also simultaneously discloses a TCP connection migratory system. According to the transmission control protocol connection migratory method and system disclosed by the invention, while the bottleneck problem caused by overlarge network throughput generated by scheduling can be solved, the server cache hit rate and the system expandability are improved, and the use of a single scheduling algorithm can be avoided.

Description

Technical field [0001] The invention relates to a message scheduling technology in a transmission control protocol (TCP), and in particular to a TCP connection migration method and system. Background technique [0002] With the continuous development of Internet technology, the number of server requests from user terminals continues to increase. Due to its own performance limitations, a single server is far from being able to meet the needs of current users. Therefore, a server cluster is required to process user terminal requests. The usual approach is to deploy a load balancing device as a TCP gateway in front of the server cluster, dispatch user terminal requests to the server cluster through the load balancing device, and send the server's response to the corresponding user terminal through the load balancing device. In the traditional TCP gateway method, since the request message of the user terminal and the response message of the server must be transferred through the load...
