A bit about OpenSwitch (OPS)
OPS And OPX, or a Bit of History
At first, OpenSwitch project and openswitch.net were governed by HP as they tried to ride the "open networking" wave. An open community, a lot of talk-based supports from several vendors, all as usual.
Efforts were made to create a set of protocols and an SAI connector to make adoption of new silicon easier.
After about 8 months, the project was handed to the Linux Foundation. A proper excuse was made - HPE said the move was a way to show the community that this wouldn’t be an effort controlled by one vendor.
