I guess many past or present Haiku net team members had once thought and talked about building a more modular, dynamic, BeOS-ish network stack. Because quick and dirty porting a “classic” BSD net stack is no fun these days, and sounds “outdated design” at time too.
Others BeOS coders did/do try also to experiment this “graph” approch too. Nathan Whitehorn in Glass Elevator context had explored a C++ one, which I tried to adapt to our C-only constraint under the src/tests/kits/net/new_stack subtree.
BTW, BONE have a kind of graph design too…
Maybe, one day, we’ll find at last enough time to finish these experimentations and write a better designed net stack. Hope is always there.
Actually, I thought it was old news after I posted it seeing the line ‘It first made its debut in the main tree in FreeBSD 3.4’. Anyway it sounded to cool not to be mentioned and now I’m glad I did.
