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 Mode Introduction is activated.
This chapter assumes that the PicOS OVS mode is active. Please see PICOS Mode Selection to modify the PicOS mode.
