Hey Navaid....
From your last couple of posts, it looks like QOS is
beating you up like it did me:) There is a book that
was released in August that, in my opinion, is the
BEST source on QOS around. It really helped explain
and clarify a lot of issues for me. It is Cisco DQOS
by Wendell Odem and Michael Cavanaugh (ISBN:
1-58720-058-9) Although it is intended for an IP
Telephony exam, I feel it is a must have for any CCIE
wannabe, and I would rank it on par with the Doyle
TCP/IP volumes as far as quality is concerned. The
authors cover it all and it is fairly large book
coming in at 900 pages. Last I checked, Amazon had it
on sale.
HTH..
