These not mutually
exclusive benefits are expounded further here.
Ubiquity and Simplicity Ethernet is ubiquitous in the LAN. Well over 90 percent of
LANs employ Ethernet, so using Ethernet services in the MAN/WAN extends this ubiquity
and enables the same plug-and-play operation that characterizes the LAN (from
an end-user standpoint, all this means is connecting a LAN switch Ethernet port to a
Service Provider-offered physical Ethernet connection).
Ethernet service also simplifies operational aspects significantly since, as per Metro
Ethernet Forum (MEF) estimates, nearly 99 percent of the data traffic flowing through
the MAN and WAN originates and terminates on an Ethernet LAN port. Carrying and
Figure 1.11 Benefits of Ethernet Services in the MAN/WAN
Why Both End Users and Service Providers Prefer Ethernet Services
Strategic Competitiveness
??? Meet customer demand
??? Potential to ???capture customer??? by
delivering new services quickly
??? Long term profitability
??? Continued Innovation and
standardization of Ethernet
New Application Support and
Lowered IT Spending
??? New video, multimedia, and other
enterprise applications will be packetized
(including voice) running over a device
with an Ethernet interface
??? Continued Innovation and
standardization of Ethernet
Strategic Appeal
Platform for Convergence
??? Service and Network convergence
??? Wide array of services can be
offered
??? Software provisioning allows rapid
introduction of new services and
revenues
??? Easier to manage one interface
No Trade-off between optimizing
Spending and Flexibility
??? No rigid bandwidth limitations
??? Rapid introduction of additional
bandwidth/services possible
??? Single interface for all services means
simplified premise equipment
management.
