Method and apparatus for inferring topology of a network

摘要

Network topology is inferred by (a) determining which non-interconnect devices are visible to each adapter in the network; (b) determining sets of adapters having visibility to identical sets of non-interconnect devices; (c) for each set of adapters having more than one adapter, associating an interconnect device to the set and assigning links to the associated interconnect device from the adapters; (d) obtaining a list of non-interconnect devices in the network excluding non-interconnect devices already having satisfied visibilities; (e) for each visible non-interconnect device in the list of all non-interconnect devices, finding an adapter not already linked to the non-interconnect device having visibility to the non-interconnect device, and assigning a link between the non-interconnect device and an interconnect device assigned to the found adapter or directly between the found adapter and the non-interconnect device; and (f) iterating steps (d) and (e) until visibility of each adapter is satisfied.
