Abstract
A method for determination of a network topology includes generating a list of device sets for a destination; removing any duplicate device sets from the list; creating a tree for the destination by introducing a root node into the tree; sorting the list of device sets for the destination by length; removing the shortest device set from the list; introducing a new node representing the shortest device set into the tree; determining whether a node in the tree represents a maximum length subset of the shortest device set, and in the event that a node is determined, connecting the new node to the determined node, or else connecting the new node to the root node; setting the identifier of the introduced node to a list of members of the shortest device set that are not included in the maximum length subset of the determined node.
