US Patent 7742432 Topology comparison

A solution for comparing topologies is provided. In an embodiment of the invention, a set of differences between the nodes and/or connectors of two or more topologies is obtained. Each difference can comprise a missing node/connector and/or a difference in an item/relationship attribute. A user interface is generated that displays one or more of the differences by displaying a subset of each topology that corresponds to the difference. In an embodiment of the invention, a user interface for comparing topologies is provided that displays each subset in a unique display area and enables a user to select the difference(s) and/or limit the difference(s) that can be selected based on the type of difference.
