Problems solved by technology

[0006] Disadvantage: Due to the long-term maintenance of the TCP connection, a large amount of resources of the hardware load balancing device are occupied
[0010] Disadvantage: Once a TCP gateway fails, all terminals pointing to the gateway will be unavailable
[0014] Disadvantage: The terminal application needs separate code to support the above logic
In addition, when the TCP gateway changes (increase / decrease), an additional mechanism needs to be implemented to notify each terminal, which further increases the complexity of terminal applications

Embodiment Construction

[0056] TCP gateway service

[0057] It can be implemented in a variety of programming languages ​​and third-party frameworks, including but not limited to C / C++, Java, Groovy, Python, etc.

[0058] Deploy multiple running instances in one or more servers according to the number of terminals that need to be accessed and the highly reliable redundancy of the system.

[0059] Since the TCP long connection link of the terminal has been taken over by the TCP gateway service, the server application can be transformed into a short connection (on-demand connection) working mode, such as TCP short connection (on-demand connection), HTTP request, etc., to reduce the price of the server application resource usage.

[0060] TCP Gateway Management Service

[0061] It can be implemented in a variety of programming languages ​​and third-party frameworks, including but not limited to C / C++, Java, Groovy, Python, etc.

[0062] According to the high reliability requirements of the system, th...

Abstract

Aiming at the application scene that TCP long connection communication needs to be adopted for communication between the terminal and the server, the system and the method for communication load balancing management at the server side are realized. With application of the load balancing of the server side, a more flexible load balancing strategy can be implemented, and the defects of static load distribution, random selection of the server by the terminal and other load distribution modes adopted when a large number of terminals use TCP long connection communication at present are also avoided. The system and the method provided by the invention can be widely applied to banks, securities and other systems which need to access a large number of terminals through TCP long connection and havehigh requirements on the overall reliability of the system.

Description

technical field [0001] The invention solves the problem of realizing load balancing at the server end when the TCP long connection is used as the communication mode in the communication between the server cluster and the terminal. It can be widely used in banking, securities and other systems that need to access a large number of terminals through TCP long connections and require high overall system reliability. Background technique [0002] TCP communication is currently widely used inter-system communication. Among them, many systems use TCP long connection as the communication method between the terminal and the server, that is, when the terminal communicates with the server, after the TCP link is established through the three-way handshake, this link is kept for subsequent reporting with the server. text newsletter. TCP long connections have certain advantages in terms of security and efficiency compared with short connections (that is, the communication method of esta...
