Running Click on SGI IRIX/Linux

[Manohar Prabhu]

Hi,

Thanks for the info.  I am considering whether and how to use Click for
my project.  One more quick question - if Click is run at user level,
what percentage of time does it spend in OS routines?  Is it approaching
100%, or is it much less than that?

Thanks,

Manohar

It depends on what you mean. Click should run on SGI IRIX out of the box
*at user level*. It can read packets using libpcap; and it might be easy
to
port the KernelTap element, which reads and writes from /dev/tun or
/dev/tap. But if you want it to run Click *in the kernel* to take
advantage
of its performance gains, you're out of luck. I think such a port would
be
very hard.

A Linux SGI/MIPS port might not be that bad, though. We would be happy
to
help make that port work.

Hope this helps -- let us know!
