An extended lifetime measure for telecommunication network
A new measure for network performance evaluation
called topology lifetime was introduced in [4, 5].
This measure is based on the notion of unexpected
traffic growth and can be used for comparison of topologies. We
discuss some advantages and disadvantages of the approach of
[4] and suggest some modifications to this approach. In
particular we discuss how to evaluate the influence of a subgraph
to the lifetime measure and introduce the notion of the order of a
path. This notion is useful if we consider a possible extension
to the set of working paths in order to support the traffic for
the time that is needed for installation of new
facilities.
