Abstract
Example methods, apparatuses, and systems are presented for discovery of how network devices are interconnected. A group of network devices may be discovered that are associated with each other may be determined. Using a system of the present disclosures, information is gathered from network devices using networking protocols and links are identified. Protocols suggest how two or more network devices are connected to each other. Every interface on the physical or virtual device may be associated with multiple types of links identified by various protocols. A weight is assigned to each link using a weight mapping table. Next a method to reduce the number of multiple links is applied. The reduction method uses the link associated with an interface with the lowest weight to map the network topology, in some embodiments.
