The Solution Framework 129
A Solution Framework
In order to meaningfully assess the very different solutions discussed in this book, a
common solution framework has been developed. This framework will be employed
in the discussion of each of the solutions to ensure a holistic assessment of the solution
that encompasses business, technology, and operational considerations, and also
to provide a measure of uniformity across the various solutions. Using this framework,
therefore, a meaningful and consistent evaluation is made possible.
The individual components of the solution framework and their respective objectives
are described next.
Technology Description This outlines the underlying technology solution and highlights
its salient features. Any evolution that the technology solution underwent to
support carrying Ethernet frames is discussed. We also look at how each of the Carrier
Ethernet attributes are (or will be) addressed in this solution, and we identify other
items necessary to delivery carrier-class Ethernet, if any. The discussion broadly details
the three operational planes of the solution??”data, control, and management.
