Abstract
In one embodiment, two neighboring nodes adjacent to each end-point node of a domain may be associated with a 'dual' (a logical structure). A first of the two neighboring nodes may be placed into a first family (and group) of the dual, while a second of the two neighboring nodes may be placed into an opposing second family (and group). Augmentations may then be performed, recursively merging and connecting the duals and/or groups, as well as connecting unplaced nodes to particular duals, families, and groups, according to forced augmentations and/or unforced augmentations where no forced augmentations exist. In the end, it may be determined whether the domain supports dual plane topologies based on whether a solution having one resultant dual with a single group in each opposing family is reached from the recursive augmentations.
