In accordance with the teachings of the present invention, a method of data drilling is presented. A network database is deployed in a network, such as the Internet, for broad-based user access. Network information is stored in the network database and is organized in layers. A graphical user interface with data objects is presented to an end user. Selecting a data object generates a query performed by a server. Each query produces more details on an initially selected data object.

Method for web-based exploration of network infrastructure

The present invention is directed to a method and system for deriving traffic demands for a packet-switched network. A novel model of defining traffic demands as a volume of load originating from an ingress link and destined to a set of egress links enables support for traffic engineering and performance debugging of large operational packet-switched networks.
