1. 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.

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.

2. A system for automatically acquiring and storing topology and traffic information of a live network for use in a network simulation tool, the system comprising:
-
an autodiscovery tool coupled to the live network that automatically, and in real time, polls devices on the live network and discovers topology and traffic information of the live network and which generates a first form of topology and traffic information; a network management system database coupled to the autodiscovery tool that stores the first form of topology and traffic information; a simulation tool database that stores a second form of topology and traffic information, the second form of topology and traffic information matching a data format required by the simulation tool database; and a topology extraction tool, coupled between the network management system database and the simulation tool database, that reads the first form of topology and traffic information from the network management system database, translates the first form of topology and traffic information into the second form of topology and traffic information, and writes the second form of topology and traffic information into the simulation tool database. - View Dependent Claims (3, 4)
