Network stack design

[Bietje]

Hi,

I'm designing a network stack. The idea is a bit linuxish. Above the drivers is a protocol independent core driver. But my question is, how can this core driver call the correct protocol handler without using a huge switch case and using every protocol as a case..

I hope someone can help,
Bietje

Using a protocol handler registry.

protocols[protocol_number]->do_something_with(packet);

Nice, thank you.
