services optimally??”and hence maximize the potential revenue from customers. It also
provides convenience and simpler management by using a single physical interface for
multiple services (as noted in the end-user benefit discussion).
Rapid Delivery Through Software-defined Provisioning/Service Additions Ethernet enables
Service Providers to modify or upgrade the services offered to enterprise customers
remotely. This capability offers the Service Providers two major benefits (apart
from speedy delivery for the enterprise user): reduced cost of introducing additional
bandwidth and an increase in revenue velocity.
For example, given the acceptably low marginal cost of deploying a 1000M versus a
100M connection, Service Providers can physically provision a 1000M port even when
the customer initially requires much less bandwidth, say 25M. In this case, the Service
Provider would only commission 25M of bandwidth (i.e., the customer can only use
25M even though the physical port can support up to a 1000M). Then, when there is a
demand for higher bandwidth in the future (as will invariably be the case), the Service
Provider can increase bandwidth remotely using software and without having to send a
technician (truck roll) to the site and without having to bring down the service for any
meaningful amount of time (perhaps for no more than a few minutes).
