The final part of the book summarizes and puts into context the landscape of the
many, very different solutions discussed in the previous section. This is meant to provide
the reader with a good understanding of the different solutions and their fit in
relation to each other.
Finally, we share our opinion on how the world of Carrier Ethernet will evolve in
the next few years. In so doing, the book attempts to provide practical and reasonably
detailed insights into the landscape of available solutions in a burgeoning field and
how they may evolve.
Any feedback is welcome and can be sent to kasim@alum.mit.edu.

Chapter 1
Ethernet: From LAN to the WAN
by Abdul Kasim
This first section provides only a cursory and informal introduction to Ethernet for
the sake of completeness to the rest of the book. Ethernet has been around for several
decades now and, as is to be expected, there is a good deal of literature available. Some
of this literature [1??“6] is noted in the reference section at the end of this chapter and
should be consulted for more comprehensive information on Ethernet.
