SONiC's support ONOS, P4, OVS, and bare-metal switches

[Syd]

Hi SONiC guys,

                         I've been reading up on SONiC (and watching the various presentations) but couldn't get a clear response for the following questions. Can you kindly provide feedback?

 

1.  Does SONiC support OVS?

2.  Does SONiC support the "traditional" style SDN setup with a controller, such as ONOS, running outside of the bare-metal switch that runs SONiC (i.e. Can I compile my own dataplane using P4, and create an application running at the ONOS network operating system to control the forwarding behavior in the switch such that ONOS runs in a box external to the SONiC switch)? 

3. If the answer to 2 is yes, then can I use P4Runtime to program a SONiC driven dataplance (e.g. OVS or the hardware switches listed here https://github.com/Azure/SONiC/wiki/Supported-Devices-and-Platforms)?

Thanks,

-Syd

Hi,

> 1.  Does SONiC support OVS?

You may install OVS on SONiC via apt-get, but it doesn't work because most switch ASICs don't support OpenFlow hardware offload.

Using OVS on SONiC with CoPP configuration might work but get poor performance.

> 2.  Does SONiC support the "traditional" style SDN setup with a controller, such as ONOS

SONiC supports REST API by sonic-mgmt-framework, but it doesn't have compatibility with ONOS SB Protocol.

SONiC also supports OpenConfig gRPC API, but it doesn't support full functionality yet.
