If you're talking hard real time, you're pretty much limited to three 
choices: C, assembler and Forth. Nothing else is going to be close 
enough to the hardware and interrupt structure.

Given that, and your requirement for open source, there's gcc for C and 
gforth for Forth. I'm not sure which assemblers are best; there are 
probably four or five usable assemblers for i86-32, but your choices may 
be more limited for other chip sets.

I would guess 98 percent of the router code these days is written in C. 
A lot of the guts of routing is already built into the Linux kernel, so 
you might be able to get away with a Scheme that compiles to C.
