OpEx and CapEx costs for realistic network scenarios

The availability requirements for today’s networks are very high. However, higher availability often comes with a higher cost. This paper describes several steps required to estimate the costs for realistic network scenarios. CapEx and OpEx are classified. An activity based approach is followed to quantify the cost of the event-driven operational processes like repair and service provisioning. We discuss activity duration and availability parameters as required input data in order to calculate the processes’ costs for realistic network scenarios. The relevant availability measures for an IP-over-Optical network are described using a triplet-representation with optimistic, nominal and conservative values. The model is applied to a reference German network scenario.
