This information describes OpenSwitch OPX and includes features, application programming, hardware virtualization, and repositories.

Features

  • Provides an abstraction of hardware devices of network switch platforms in a Linux OS environment
  • Uses standard open source software including an ONIE installer, and an unmodified Linux kernel based on Debian Jessie distribution
  • Provides a robust and flexible programmatic API — control plane services (CPS)
  • Accesses OpenSwitch networking features using either the Linux standard API or the CPS
  • Provides a rich set of networking features including full access to the NPU ACL and QoS functionality using the CPS

Application programming

Provides an object-centric API for application development to implement custom applications using a well-defined object model, and set of programmatic APIs. The object model is defined using YANG modeling, and the APIs support Python and C/C++ programming languages. See Application programming for more information.

Hardware virtualization

OPX software supports hardware virtualization (or simulation). Software simulation of basic hardware functionality is also provided (“white board”), and the higher layer software functionality can be developed and tested on generic PC/server hardware. See Hardware virtualization for more information.

Repositories

The repository structure is organized around the main architecture components:

  • NAS and SAI
  • PAS and SDI
  • Infrastructure
