Claim Text:
1. A bridge apparatus connected between a first network to which first equipment is connected and a second network to which second equipment is connected, the apparatus comprising: a connection detecting device configured to detect connection of the second equipment to the second network; a management device configured to allocate a virtual device processor to the second equipment in accordance with detection of the connection of the second equipment to the second network, wherein the virtual device processor stores bridge operation attribute information that indicates a response policy for the second equipment or a response policy for attribute values of the second equipment, and makes a bridge operation between the first network and the second network, the attribute values including a variable value and a fixed value, the attribute values indicating properties of the apparatus, the variable value being variable since the apparatus is fabricated, the fixed value being invariable since the apparatus is fabricated; a disconnection detecting device configured to detect disconnection of the second equipment from the second network; and a bridge operation control device configured to direct the virtual device processor to change contents of the bridge operation in accordance with the bridge operation attribute information, when the disconnection of the second equipment from the second network is detected, wherein the virtual device processor comprises an update device configured to update contents of the bridge operation in accordance with the bridge operation attribute information assigned from the bridge operation control device, and in response to a request from the first equipment, the update device switches between a first operation and a second operation in accordance with the bridge operation attribute information, the first operation being the update device responds to the request, the second operation being the update device forwards the request to the second equipment.
