An apparatus for updating a device, includes: a card configured to include a first device; a controller configured to acquire first circuit data from the card and to update a second device by using the first circuit data; and a storage unit configured to store, from the card, second circuit data for updating the first device, wherein the controller acquires the second circuit data stored in the storage unit and updates the first device by using the second circuit data.

Apparatus and method for updating a device

A network topology collection device determining a network topology which indicates a connection state of a route prepares opposed topology information which indicates the connection state between a collection node to which the network topology collection device itself belongs and opposed nodes which respectively terminate routes terminated by the collection node, collects opposed topology information of a node directly or indirectly routed to the collection node, and determines a topology of an entire network based on the opposed topology information collected. Also, in a hierarchized route, the collection device determines a network topology of a route in a specific hierarchy based on opposed topology information in the hierarchy and opposed topology information of a route in another hierarchy.
