Load balancing equipment strategy custom-built system and method

Abstract

The invention relates to the network information technical field, and comprises the internet, an network card drive, a data packet reception, a load balancing equipment strategy subsystem, a data packet emission and an application server; the method comprises the steps of customizing and storing script code files and a script explainer in a memory of the load balancing equipment; employing the scripts to analyze and process the received data packets, and sending the data packet according to the load balancing equipment strategy described by the matched script; customizing and storing a new script when an alternative script cannot satisfy the needs; employing the method of replacing the script to update the load balancing equipment strategy. The load balancing equipment strategy employing the system can be switched in real time, the internet service is not interrupted, and the strategy can be updated without updating system software.

Description

technical field [0001] The invention relates to the field of network applications, in particular to a system and method for customizing a policy of a load balancing device. Background technique [0002] Load balancing, the English name is Load Balance, which means to balance the load (work tasks) and distribute them to multiple servers for execution, such as Web servers, FTP servers, enterprise key application servers and other mission-critical servers, so as to jointly Complete work tasks. Load balancing is based on the existing network structure, which provides a cheap and effective method to expand the bandwidth of network devices and servers, increase throughput, strengthen network data processing capabilities, and improve network flexibility and availability. Load balancing has two meanings: first, a large amount of concurrent access or data traffic is distributed to multiple node devices for separate processing, reducing the time for users to wait for a response; seco...

Problems solved by technology

For example: using the command line to customize the load balancing device policy (CLI), its disadvantages are high manual participation in policy customization or update, and cumbersome operations; the policy configuration process is complex and requires high technical requirements for operators; policy configuration is prone to errors and risks High; the customization or update of complex policies requires equipment upgrades, which will result in temporary unavailability of network services and high cost; and its policy configuration files can only express static policies, and can only configure inherent functions of the device, and cannot expand the functions of the device , such as it can express that the device can handle the HTTP protocol, it cannot express what kind of data packet is the HTTP protocol, it can express which algorithms the device supports, it cannot define new algorithms, and the algorithm requires the support of the device software. In summary, existing technical methods exist Two unsolvable problems: First, with the rapid development of network applications, new network application requirements are constantly generated. When the policy needs to be updated, the network administrator of the equipment purchaser needs to contact the equipment manufacturer's engineer to request policy customization. The network administrator of the purchaser cannot customize it himself, which affects work efficiency; secondly, after the equipment manufacturer’s engineer customizes or modifies the policy, he needs to upgrade the software system of the equipment, causing the network service interruption of the load balancing equipment

However, there is no precedent for applying scripting language to the field of load balancing device policy customization or update
