6 shows a fairly complex set of (positive and negative) factors influencing
the demand for Carrier Ethernet, both directly and indirectly, and largely from the
standpoint of the Service Provider.14 Some key points can be observed:
?– There are eight key influencers identified here: Applications (supported),
(Improvement in Service Provider) Economics, Regulation, Substitutes (to Carrier
Ethernet), Technology (improvements), Competition (amongst Service Providers),
Fiber Deployment, and Standardization (of Carrier Ethernet).
?– Each of these influencing factors is itself influenced by a set of secondary factors: for
instance, the (Improvement in Service Provider) Economics is invariably a function of
the market /end user price of Carrier Ethernet, the cost to Service Providers, and so on.
Such factors are assumed in the analysis but not explicitly noted to keep it simple.
?– Almost all the factors can be considered as direct influencers of Carrier Ethernet
demand (with the exception of Competition and Technology, which are indirect).
Note that Technology is both a direct and indirect influence, i.e., it influences demand
for Carrier Ethernet via Economics, Standardization, and Applications, as
shown in the figure.
