WHAT IS NAP?

The Network Availability Program (NAP) enables users to predict the availability and reliability of

communication networks. The NAP network availability model utilizes an extended Reliability Block

Diagram (RBD) methodology that addresses the specific characteristics of network elements and their

connections.

In addition to predicting network availability, NAP also provides criticality rankings that identify weak

spots in the network.

WHATS INCLUDED IN NAP?

NAP provides many time-saving features to allow users to quickly construct the network diagram. These

include a parts library facility that allows users to import their parts data in convenient groupings, a

network element library facility that allows users to construct common network element diagrams and a

fully interactive network diagram const ruction facility.

One of the important features of NAP is that it allows the modeling of data flow in different directions along the same network

path. This means that users need not be specific about the direction of data flow in selected parts of the network. NAP will

then automatically determine the allowable paths between a source and target, and hence determine the minimal cut sets

that determine the availability of the network.

MODELING NETWORKS

Complex or simple networks may be modeled using NAP. Network elements may be logically modeled right down to part

level using the powerful NAP pagination facility. Individual network element diagrams have been extended beyond traditional

RBDs to allow users to model multiple interfaces and their interactions with common equipment.

Users may also restrict the analysis to network paths traversing a limited number of network elements (limiting the hop

number). This useful feature eliminates unrealistic snake-like paths in complex networks.
