Thus, the enterprise will waste bandwidth
and pay more (than necessary).
As most of the applications, including increasingly voice (using Voice over IP or VoIP
supported by IP PBX) are being packetized, then pretty much all applications/services
an enterprise uses can be transported over an Ethernet access platform most (if not all)
supporting equipment (for instance, a storage switch) now have an Ethernet interface.
Employing Ethernet as the common access interface not only simplifies the connectivity
and the equipment necessary, but also enables the capability to optimize the
bandwidth across multiple services. What this means is the likelihood of the enterprise
reducing its recurring bandwidth cost. This when complemented with the typically
lower cost of Ethernet makes it even more appealing reinforcing this appeal is the fact
that new services can be added rapidly (this is a big advantage to Service Providers as
well; see the following sections).

(usually by truck/vehicle).
Ethernet: From LAN to the WAN 31
The operational costs (OPEX) are also reduced due to simplified management of just
a single (and familiar) connection, as opposed to managing several different types of
connections.
