I am very sorry Mr. Sprunk
Yesterday nigth a very good system analyst give me a lot of explanation
about it.
I dault that on Comer, or Tanembaum or IBM TCP/IP Red Book could give me
some explanation about that
Nobody knows how the algorithm implemented by CISCO or Extreme or Juniper
works !!!
Therefore the explanations that I have yesterday were very clear for me ...
and in details
For that I look for help in this list
Best Regards
Giuliano
