Load balancing module in financial real-time trading system

Abstract

The invention discloses a load balancing module in a financial real-time trading system, which is located between a terminal and a background server cluster. The load balancing module comprises at least two servers, each load balancing server is provided with a foreground network card and a background network card and adopts a VRRP (virtual router redundancy protocol). The foreground network cards are in one set and are externally provided with a unique IP (internet protocol) address and a unique MAC (media access control) address and internally divided into a master control foreground network card and the reset of backup foreground network cards. The background network cards are also in one set and are externally provided with a unique IP (internet protocol) address and a unique MAC (media access control) address and internally divided into a master control background network card and the reset of backup background network cards. Each load balancing server operates a load balancing program, and the load balancing program comprises a load balancing process, a multi-machine hot standby process and a monitoring process; and in the multi-machine hot standby process, the master control foreground network card and the master control background network card determined by the VRRP protocol are monitored, and the master control foreground network card and the master control background network card must be on a same load balancing server.

Description

technical field [0001] The application relates to a real-time financial transaction system, in particular to a communication module located between a terminal and a background server. Background technique [0002] When people use financial cards such as bank cards and prepaid cards for consumption transactions, they use the financial real-time transaction system. see figure 1 , which is a simple schematic diagram of the financial real-time trading system, including: [0003] —Multiple terminals 10: for reading financial card information, sending a transaction request including financial card information and transaction information to the background server 50, and receiving the transaction result returned by the background server 50. The terminal 10 includes a card swiping machine (also called a POS machine), a cash register integrated with a card swiping function, etc., [0004] ——A background server 50: used to receive transaction requests from each terminal 10, process ...
