Network Availability Program™
Isograph's Network Availability Program (NAP)™ enables users to
predict the availability and reliability of communication networks.
The NAP network availability model utilises 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. NAP
provides many time-saving features to allow users to quickly
construct the network diagram.
What's 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 construction 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.
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
