Abstract: A packet rewriting apparatus is arranged between a tunnel end point and a switch that refers to content of the original header to determine processing to be applied to a packet. The packet rewriting apparatus is provided with: a packet rewriting rule storage unit that stores packet rewriting rule(s) for writing information corresponding to a virtual network identifier included in an additional header of a packet outputted from a tunnel end point, to a prescribed region of the original header; and a packet rewriting unit that rewrites, in accordance with the packet rewriting rule, to a packet in which information corresponding to the virtual network identifier is written to the original header of a transmitted packet.

Abstract: A control apparatus includes a virtual network management unit configured to manage the virtual network using mapping information that associates configuration information on a physical network and configuration information on the virtual network and a control unit configured to set control information in the physical node on the physical network, based on the mapping information, thereby causing the physical node to operate as a virtual node on the virtual network. The control apparatus is configured to determine an assignment status of a port of the physical node with respect to the virtual network, based on the mapping information. Then, the control apparatus causes a predetermined port status display apparatus to display the assignment status of the port with respect to the virtual network.

Abstract: Chained terminals have a carrier (1) with opposite first and second side edges and terminal fittings (2) coupled to the first side edge of the carrier (1). The carrier (1) is formed with feed holes (6, 7) in correspondence with the respective terminal fittings (2). A widened portion (8) is provided along the first side edge of the carrier (1) and the feed holes (6, 7) are deviated towards the second side edge along the width direction. Thus, strength can be increased by as much as the carrier (1) is widened, and production efficiency can be increased by increasing a conveying speed.
