An information processing unit comprising: a location information transmission section adapted to transmit, to a further information processing unit connected to the information processing unit, location information indicating a location of a connection target unit to which the further information processing unit is to be connected; a location information determination section adapted to determine whether the further information processing unit and the connection target unit exist in the same LAN by referring to the location information before being transmitted; and a location information conversion section adapted to convert the location information to be transmitted into location information explicitly specifying a remote access connection according to a determination result of the location information determination section, characterised in that each of the further information processing unit and the connection target unit is connected by a private address to a node belonging to the same LAN as a corresponding one of the further information processing unit and the connection target unit and having a unique node identifier, and when the location information conversion section converts the location information to be transmitted into said location information explicitly specifying a remote access connection, the converted location information comprising: a schema identifier explicitly specifying remote access connection; the unique node identifier assigned to the node to which one of the further information processing unit and the connection target unit is connected; and the private address of one of the further information processing unit and the connection target unit. a location information transmission section adapted to transmit, to a further information processing unit connected to the information processing unit, location information indicating a location of a connection target unit to which the further information processing unit is to be connected; a location information determination section adapted to determine whether the further information processing unit and the connection target unit exist in the same LAN by referring to the location information before being transmitted; and a location information conversion section adapted to convert the location information to be transmitted into location information explicitly specifying a remote access connection according to a determination result of the location information determination section, characterised in that each of the further information processing unit and the connection target unit is connected by a private address to a node belonging to the same LAN as a corresponding one of the further information processing unit and the connection target unit and having a unique node identifier, and when the location information conversion section converts the location information to be transmitted into said location information explicitly specifying a remote access connection, the converted location information comprising: a schema identifier explicitly specifying remote access connection; the unique node identifier assigned to the node to which one of the further information processing unit and the connection target unit is connected; and the private address of one of the further information processing unit and the connection target unit.
