Actually I think P4 programmable switch ASICs such as Barefoot are going to become more prevalent over time and hence features will be available in software.

- kazen44 5y agohasn't P4 been kind of dead in the water for the last couple of years.
- mmmBacon 5y agoP4 programmability is available in Cisco Silicon One so wouldn’t call P4 dead in the water. Cisco Silicon One is meant to go head to head against Broadcom. https://www.cisco.com/c/en/us/solutions/collateral/silicon-one/datasheet-c78-744312.html https://www.cisco.com/c/en/us/solutions/collateral/silicon-o... In other merchant silicon, while not P4, Broadcom has offered their own proprietary programmability in Trident 3/4. I think adoption has been slower more due to lack of relevant domain expertise in software as well as relative inability of pretty much anyone to properly model the impact of routing features on a production network than anything else. P4 is being widely adopted at the NIC level.
