Is there any product similar with AFTR?

AFTR is short for "Address Family Transition Router", a stand-alone, user mode application that implements a Dual-stack lite in ISC family.

Is there any other products imp开发者_C百科lements a Dual-stack lite similar with AFTR? I want to learn it by comparing it with other products, and evaluate the performance of it.

Thanks~

A colleague has tested A10 with AFTR functionality, and I know that certain Brocade products can also do AFTR.
