Because the solution description is meant to be reasonably detailed but cannot be comprehensively
detailed due to space constraints, all relevant standards are referenced.
Drivers for This Solution Here, we provide insights into the original reason that this
solution was developed (e.g., for introducing resiliency to voice connectivity). And we
look at how this solution has evolved to accommodate Carrier Ethernet delivery.
Solution Fit This discussion focuses on the scenarios where the solution is better
suited (e.g., low competition, incumbency, specific architectures, demand for other non-
Ethernet services); conversely, if necessary, we identify the scenarios where the solution
does not make any business sense.
Benefits and Shortcomings This discussion outlines the tangible benefits of employing
this solution to deploy Carrier Ethernet services. For instance, a solution could inherently
offer several of the carrier-class attributes or be optimal in certain scenarios or
entail the lowest capital expenditure. Shortcomings, if any, are also similarly covered.
NOTE Often this and the previous section overlap but this is meant to explicitly identify
the specific advantages/disadvantages.
