Are you aware that there are 496 search results that match TCP/IP in the book category at Amazon? Which are the best? Periodically I’ll be posting a recommended book that I’ve found to be better than the average cut-down-the-forest style of writing – you know, reprint the RFCs, restate the ITU standards, etc. It goes without saying that some books are destined to become classics – TCP/IP Illustrated Volume 1 by the late Richard Stevens is one such example and is still my overall favorite in the TCP/IP category.
One of my highly recommended favorites in the VoIP category is Delivering Voice over IP Networks, 2nd Edition, Daniel Minoli, Emma Minoli, ISBN 0-471-38606-5, August 2002. The best thing about it is that it’s printed on acid-free paper (just kidding, but it does state that inside the cover.). It is also available in an e-book version (acid-free as well!).
This book covers nearly every major switching, call control, and transport protocol with respect to VoIP including: MPLS, H.323, MGCP, SIP, Megaco, SCTP, RTP, etc. It gets into QoS, telephone number mapping (ENUM), and of course, details between the many G.xxx speech coding standards. I really like that you can read deep into the technical details or skim the basics – from Markov traffic models to packet headers. Highly recommended.
