A. Demand refers to the amount of OTN interfaces within a single network element.
B. Demand refers to the required capacity of a single network element in terms of bandwidth.
C. Demand refers to the required number of trails to be automatically created to meet design requirements.
D. Demand refers to one or more client signal.
Answer
D. Demand refers to one or more client signal.
Explanation
In the context of Nokia’s Evolved Packet Transport (EPT), a demand represents the client signals or services that need to be transported across the network. It does not refer to the capacity, number of interfaces, or quantity of trails on a single network element.
When designing an EPT network, planners start by defining the demands – the specific client signals and their required bandwidth that must be carried from one location to another over the optical transport network. Based on these demands, the EPT planning tools determine the optimal network architecture, including the trail engineering and capacity required on each network element to efficiently transport the demands while meeting performance and resiliency requirements.
So in summary, a demand in EPT refers to the client signals to be transported, which serve as the inputs to the network planning and optimization process. The demands drive the design of trails and capacity allocation across the network elements to ensure the client traffic can be carried effectively.
