• Windows 11

 

Linux 

• Ubuntu 18 and above
• CentOS 7 and above
• Linux Red Hat 6 and above

Qntrl Bridge may be installable on other OS versions, but full compatibility and performance are not guaranteed.

 

System requirements 

Qntrl Bridge requires a minimum CPU configuration of a quad-core processor running at a speed of 2+ GHz. Additionally, it necessitates a minimum of 2 GB RAM and 1 GB of file storage.

 

Component	Minimum	Recommended
Processor	4 cores	16 cores
Processor Speed	2 GHz	3 GHz or above
RAM	2 GB	16 GB
Storage	2 GB**	5 GB**

**Storage refers to the amount required for Bridge installation and operation logs.

 

Java  Requirements

Qntrl Bridge is bundled with Java version 1.8.0_252 by default. It is set to run with the bundled Java, requiring no additional configuration. If the bundled Java is not compatible with your operating system, you can modify the Java path in the wrapper-bridge.conf file.

​

• Minimum Required JRE:1.8.0_172
• Recommended JRE:1.8.0_252
  

​

Using a lower JRE version may result in encryption-related issues.

• Default JVM memory: 512 MB
• Memory size can be adjusted as needed within the wrapper-bridge.conf file.

 

Java Service Wrapper 

Qntrl Bridge leverages the Tanuki Java Service Wrapper (v3.5.11) to ensure smooth process launching, monitoring, and deployment.

 

Internet Connectivity 

A stable internet connection is necessary for Qntrl Bridge operation.

• Minimum Speed: 50 Mbps
• Recommended Speed: 100 Mbps
