Embodiment Construction

[0025] The load balancing method based on the combined application of the forward isolation device and the isolation gateway of the present invention adopts a private health detection mechanism based on the TCP protocol for the defects of the existing load balancing ICMP health detection mechanism in the health detection. , which eliminates the limitation of the ICMP detection of the load balancing function itself in the application scenario where the forward isolation device is combined with the isolation gateway.

[0026] The specific implementation of the load balancing method based on the combined application of the forward isolation device and the isolation gateway of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0027] figure 2 A flowchart showing the load balancing method based on the combined application of the forward isolation device and the isolation gateway of the present invention, including the following...

Abstract

The invention provides a load balancing method used by combining with an isolation gateway and based on a forward isolation device. The method includes that business processing rules of the forward isolation device are configured, transmission control protocol (TCP) business messages are allowed to pass in forward direction, and only response messages of set formats are allowed to pass in the reverse direction; a private health detecting mechanism based on the TCP detects health conditions of each chain; and forward business data is distributed according to the health conditions of each chain. By deploying detecting messages based on the TCP on the upper portion of the isolation gateway on two sides of the isolation device, the health conditions of each chain are detected, load balancing is conducted according to the health conditions, load balancing efficiency is high, deploying of situations with bandwidth expandability and network safety is achieved, and requirements for high safety, high bandwidth and high reliability of combining of the forward isolation device and the isolation gateway are met.

Description

technical field [0001] The invention relates to load balancing technology, in particular to a load balancing method based on the combined application of forward isolation devices and isolation gateways. Background technique [0002] Positive isolating device: the forward-type special safety isolating device for electric power network, which is a safety protection device with special hardware with various control functions, located between the dispatching data network and the public information network, used for safety One-way data transfer from Zone I / II to Security Zone III. [0003] Isolation gateway: A gateway that isolates two connected networks based on unidirectional forwarding, including but not limited to routers, switches, or servers. [0004] Load balancing: According to the pre-configured load balancing algorithm, user traffic accessing the same IP address is distributed to different servers. It distributes user traffic to multiple equivalent servers through vir...
