DriveNets Total Cost of Ownership

WHITEPAPER

The Distributed, Disaggregated Chassis (DCC), as proposed by the Telecom Infra Project (TIP) and deployed in AT&T’s core
network, is an open, standard and field-proven solution leveraging network cloud architecture.

The comparison between cloud-based solutions and legacy chassis-based solutions should be based on network resource efficiency. In a cloud-based solution, the efficiency and
value are based on the abstraction of all hardware resources. This abstraction increases hardware utilization to a new level
of efficiency. In order to realize this potential, a new approach needs to be taken for TCO evaluations. This needs to take into
account the real cost per network service, not just the cost per network element.
