[e2e] Router ip stacks!

[Amr A. Awadallah]

Hi,

  I am researching router ip stacks and would appreciate pointers to
implementations in this field either from open sources or private
companies that license such stacks. Please drop me a line if you know of any. 
The list I collected so far is attached at end of this e-mail.

Thanks in advance,
