Software-based Border Router

Thank you for the prompt response.  Just to clarify my previous post, I was actually referring to Linux/Unix-based routers.  We've been considering this solution because presently we don't have any budget for equipment acquisition this year.

To be honest, I came across Vyatta Core while searching for viable Linux/Unix-based solution that we can adopt and I'm currently reading its reference guides.  Has anyone here used this software before?  

Thanks a lot.

Software based routers (e.g. Cisco 7200 series) have been used as border
routers for many years - this is hardly anything new. The question you
should ask is probably: Can such a router handle a full link's worth of
DDoS using minimum sized packets? The answer, of course, depends on your
link capacity, the router itself, features enabled (ACLs, QoS, ...) etc.

There are quite a few people using Quagga based boxes running Linux or
FreeBSD as border routers - this is a possible solution too, giving
you more bang for the buck than a traditional software based router from
the big vendors. Make sure you have enough expertise for the relevant OS
and routing software available.
