</p><p>"It isn't every day (pun intended) that one of the true Old Guard
 writes and publishes a book, and it behooves us to take notice. In this
 case, the author's expertise and his subject matter are of particular 
timeliness, because of the worldwide resurgence of activities with 
regard to next-generation network architectures, that is, a replacement,
 or upgrade to the Internet (dare one say "Internet 2.0"?).
</p><p>John Day is a well-known scholar of historical cartography, and 
this book, in a way, is a roadmap of network architecture. The roadmap 
starts back in 1970, tracing from the roots of connectionless 
packet-switched dynamically routed systems such as Cyclades, and the 
ARPANET, through to recent discussions on multihoming, multicast, and 
mobility, with a view along the way of naming, addressing, protocol 
stack design, protocol design, and concepts of layering.
</p><p>That description makes the book sound fairly standard in terms of
 structure and content, but it isn't. The book includes many discursive 
elements whose intent is to provide a collection of patterns. Design 
patterns originated in the building trade as a way for crafts people to 
pass on successful methods of construction (in the sense of affordable 
and noncollapsing) to less-inventive people (or people who want to spend
 their inventive efforts in different areas). Software engineers picked 
up on this idea, applying the techniques in both the microscopic world: 
patterns allow you to decide what algorithm is applicable in solving a 
problem in the small; and the macroscopic world: architectural patterns 
allow you to decide on an approach to breaking down a large system into 
the right kind of components.
</p><p>Essentially, this book does the same thing, at the protocol stack
 level, and at the system level, with a collection of historical and 
contemporary examples to support the arguments.
</p><p>The book makes interesting reading, especially as it represents a
 fair balance in reporting the early ideas that came not just from the 
United States, and restates the importance of the Opens Systems 
Interconnection (OSI) model (not the ISO protocols) in understanding 
layering and beads-on-a-string, as well as reasserting the use of the 
model in clarifying the perennially confusing concepts of names, 
addresses, and routes.
</p><p>The book begins with a discussion of seven principles that 
emerged through the early history of networking (I won't spoil the book 
for readers by listing them here), and ends in the tenth and final 
chapter, entitled "Backing Out of a Blind Alley," with an appeal to 
fundamentals. Essentially, the author points out that researchers 
(especially academics) are strongly motivated to keep moving on with 
claims of ever-newer tricks, but rarely to consolidate these tricks into
 a set of principles that stand for a long time (because then they would
 have to completely change the topic of their research). Thus uncovering
 a foundational theory of networking would put a whole generation of 
networkers out of work (or funding at least).
</p><p>The book is peppered (saltily) with fine quotes and fascinating 
asides from philosophy (for this reader, especially, the Chinese 
diversions were most novel and illuminating). Illustrative of the range 
is that one finds Wittgenstein and Dave Clark, Confucius, and Dr. 
Seuss—Frege's useful reminder that "The sign '=' should be read as 'is 
easily confused with'" would make an excellent IETF T-shirt.
</p>I found the book extremely readable and enjoyable, and although I
 might argue with some of the opinions in the book, I think that this is
 just more evidence that I should recommend the book to anyone 
interested in knowing why we are where we are in networking, and being 
better informed about where we should go next."<br clear="all"><br>-- <br>P2P Foundation: <a href="http://p2pfoundation.net/" target="_blank">http://p2pfoundation.net</a>&nbsp; - <a href="http://blog.p2pfoundation.net/" target="_blank">http://blog.p2pfoundation.net</a> <br>
