Abstract:
Traffic data evaluation apparatus for evaluating traffic in a real network using dynamic routing where traffic routes are determined before transfer of data, comprising:a) traffic data collection means to collect data with respect to a real traffic flow in the real network, b) network modeling means to model the network through a virtual network having virtual links without capacity restrictions imposed thereon, wherein said virtual network models the real network but said virtual links do not exist in the real network; c) network load evaluation means including mapping means to map the real traffic flow of the real network onto the virtual network assuming optimal dynamic routing, and comparison means to compare capacity used for each virtual link with the capacity assigned thereto; and d) network modification means for changing dynamic routing, where traffic routes are determined before transfer of data, by modifying the real and/or virtual network by adding new links and/or nodes thereto based at least in part upon comparisons performed by said comparison means.
