I recommend you all look at The Click Modular router http://www.pdos.lcs.mit.edu/click/
which is a step in the right direction. Of course given the current architecture it may be very hard to adapt it to this kind of model. I led/worked on a project at Wind River Systems to do a multi-instance stack based off of the 4.4 BSD lite code. I can tell you that without quite a bit of rearchitecting what you get is always a hack. There are (were?) over 100 global variables in the 4.4BSD lite code. I've not counted on 4.4 or -CURRENT so I can't say. There are also the issues of the locks though I suspect in -CURRENT (since the kernel is MP) you have handled these in some way. An extensible, multi-threaded TCP/IP would NOT look like the 4.4BSD-Lite code. Is this a goal of FreeBSD now? I am working on some things to make this possible but it is independent of FreeBSD and very very early days as yet.
