snabbp4

Well, I switched to Lua because Snabb apps are built in Lua, and because the Snabb toolkit will ideally provide a lot of functionality for the runtime that I won't have to build myself. And Snabb is really quite impressive in itself. That said, Elixir is an awesome language, and lovely to write lexer/parsers in. I took me only a few hours to build a functioning parser in Elixir, compared to several days to build one in Lua. The p4 parser/lexer in Lua is here: https://github.com/esbullington/snabbp4 Next step would be to generate the parse graph.

Someone has started working on P4 support [0] for Snabb Switch [1]. I think a language like P4 will be great for sharing switching logic. I hope we will see re-usable modules written in P4 that can be shared. 0. https://github.com/esbullington/snabbp4 1. https://github.com/snabbco/snabb
