(This chapter has provided
a plausible evolution of the solution landscape)
It is difficult to gauge the time it will take to evolve toward fewer, more optimized
Carrier Ethernet solutions. The existing solutions, largely depreciated, imposing a low
operational overhead, and offering sufficient carrier-class features (as well as developing
new ones), will continue to provide a compelling rationale for quite some time. And
so it would be very useful to understand these solutions in some depth ??”which is what
this book strives to provide.
