Abstract
Abstract Method and apparatus for automatically populating a network simulation tool database with network topology and/or traffic information. A topology extraction tool is provided for reading the topology and traffic information in a network management system database, and translating this information into a matching data format required by the simulation tool database before writing the information to the simulation tool database. This automatic method avoids the time-consuming and error-prone prior art manual method of constructing a network model.

Claim 2
Dependent Claim
147 words
A network topology extraction tool comprising: an autodiscovery tool, coupled to a live network, that automatically, and in real-time, polls devices on the live network to generate a first form of topology and traffic information of the live network, the first form of topology and traffic information being stored in a network management system database; a data reader coupled to the network management system database to read the first form of topology and traffic information from the network management system database; a data translator coupled to the data reader that translates the first form of topology and traffic information into a second form of topology and traffic information matching a data format required by a simulation tool database; and a data writer, coupled between the data translator and the simulation tool database, that writes the second form of topology and traffic information into the simulation tool database.
