|---|---|---|---|---|---|---|---|
| ACS | no? | yes? | SONiC | SAI | announced in 2015, not sure if this is an actual product or just the predecessor to SONiC? | ||
| cumulus | yes | yes | FRR | Linux kernel | switchd | ||
| picOS | yes | yes | OVSDB? | openflow | |||
| ONL | yes | yes | openflow | ||||
| switch light | Switch Light OS | indigo | ivs/openflow? | ||||

| OpenSwitch OPS | no | yes | OVSDB | openNSL | deprecated? | ||
| OpenSwitch OPX | yes | yes | Linux/CPS adapter | SAI | APLv2, various? | ||
| Noviware | yes | proprietary? | P4/openflow | proprietary? | |||
| Vyatta/VyOS | yes | quagga | Linux | Linux (software) | various open-source | runs on x86 hardware for software forwarding | |
| snaproute | CN-NOS | FlexSwitch | asicd | ||||

| ONOS | openflow/netconf/openconf/... | APLv2 | wiki | ||||
| openvswitch | N/A | OVSDB | software? | APLv2 | software forwarding | ||
| ZebOS | yes | ZebM/ZebOS-XP | ZebIC | proprietary | |||

I haven't decided where these fit yet:
- Ryu (openflow controller, written in python)
- openstack neutron (datacenter virtualization orchestration?)
- open daylight
