The OpenFlow protocol is driven by ONF (Open Networking Foundation), a leader in software-defined networking (SDN). The OpenFlow protocol encompasses three essential components of an SDN framework:
- A physical OpenFlow switch.
- A virtual OpenFlow switch to manage virtual machines.
- An OpenFlow controller, to organize all network pieces.
The following websites provide detailed information on Open vSwitch and the OpenFlow protocol.
- Open vSwitch: http://openvswitch.org
- OpenFlow: http://www.opennetworking.org/sdn-resources/openflow
PicOS can run in two different modes:
- OVS (Open vSwitch) mode: In this mode, PicOS is dedicated and optimized for Openflow applications.
- L2/L3 (Layer 2/Layer 3) mode: In this mode, PicOS can run switching and routing protocols, as well as OpenFlow applications
In OVS mode, L2/L3 daemons are not running; the system is fully dedicated to Openflow and OVS.
In L2/L3 mode, L2/L3 daemons are running, but OVS can also be activated if CrossFlow is activated.
This chapter assumes that the PicOS OVS mode is active. Please see PicOS Mode Selection to modify the PicOS mode.
On N3048EP-ON and N3132PX switches, run "save_config" command when set OVS commands. Otherwise, the OVS configuration will be lost after PicOS reboot. For detail, please refer to Configuration Saving Guide.
