Open ROS

Key features

  • Open Architecture
  • Linux inside switch CPU (Debian/Ubuntu)
  • All ROS functions as Linux process
  • Support of any linux compatible devices, binary kernel modules supported.
  • Virtual interfaces to flow traffic switch<->linux
  • Internal virtual loopback to allow switch control
  • Simple setup with configuration files
  • Works on ARM and x86

OpenROS system provides user ability to develop and run customized applications side-by-side with the ROS system. These applications can use standard Linux interfaces to send/intercept network traffic from the switch ports, get access to special means to process RAW traffic through Linux Sockets and can use all means of management to control switch behaviour.
Ability to preprocess (filter/select) traffic on the switch to reduce the possible load on the CPU.

Unidirectional sending of selected network traffic to a user application through LINUX- TAP interface and/or LINUX SOCKET bidirectional traffic exchange between selected port/vlan and user application through Linux TAP interface.

TCP/IP-connectivity between switch OOB stack and user application, using dedicated point-to-point Linux TUN interface.
OpenROS runs as a process inside Linux,on the switch CPU (internal, or integrated), where Packet Processor is either connected with PCIe interface.

Larch Networks ready-to-use hardware platforms
with optional POE+ models support, different
power budgets and power options.
