There's some cool tech going on at barefoot (https://barefootnetworks.com/ https://barefootnetworks.com/)
I don't know much about the technical details, but the pitch I've heard is that it gives you ASIC level performance with more flexibility to reprogram the chip (not full FPGA).
- ra1n85 6y agoYeah, it's an interesting approach. They're basically allowing you to define packet processing with P4 on their Tofino family of chipsets: https://p4.org/ https://p4.org/ That said, there's only so much you can do in a chip before considerable tradeoffs are going to be made. They're not going to offer the same level of flexibility you get out of a general purpose CPU, but may not have same the restrictions of most fixed pipeline chips - their product sits somewhere in the middle. Also, P4 seems to sit in a space complex enough to make it unreasonable for most network shops - it's not for your average enterprise or service provider network.
