Architectural Design Guidelines

Throughout its development OpenRG has strictly maintained standards-based architecture, design and interfaces. Working within this design gives OpenRG several important advantages:

• Robust development environment
  Hardware Vendors receive a familiar and widely documented development platform on which to develop drivers and add applications.

• Single-threaded client application
  OpenRG's single-thread technology enables different applications and services to run in a single thread, as opposed to conventional multi-process and multi-threaded approaches, where each application and service has its own process or thread. This technology improves performance of servers under heavy load, reduces footprint by 30%, and reduces per-connection memory allocations by up to 99%.

• POSIX compliance
  Standard well-documented APIs to client applications. OpenRG uses Linux POSIX APIs that enable the addition of proprietary or third-party applications on top of OpenRG.

• Standard driver interface
  OpenRG maintains standard and well documented driver interfaces to enable support of standard devices.

• Scalability
  OpenRG's standards-based design can easily keep up with advancing kernel versions, enabling smooth integration of new modules and technologies.

• OS support
  OpenRG provides support for multiple operating systems. When adding support for an additional operating system, little or no work is needed on the client applications, allowing the engineering effort to focus on porting the kernel and drivers.
