摘要： A frame transfer method transfers frames in a service provider network that couples to a user network in a broadband network in which a plurality of user networks are coupled via the service provider network. The method receives a user frame that is input from a user network by a first edge switch within the service provider network that is coupled to the user network, and adds header information to the user frame in the first edge switch and outputs the frame that is added with the header information from the first edge switch to a core switch within the service provider network. The header information includes a first address that is unique within the service provider network and is allocated to the first edge switch, a second address that is unique within the service provider network and is allocated to a second edge switch coupled to a user network that becomes a destination, a VLAN value allocated to a network within the service provider network, a first port identifier identifying a port of the first edge switch that receives the user frame, and a second port identifier identifying a port of the second edge switch.

摘要： An optical communication unit includes a light emitting-receiving element provided in such a manner that an optical axis thereof is set perpendicular to an electric circuit substrate, a reflecting plate for changing a direction of the optical axis, and a filter. The reflecting plate is provide outside the filter so as to be freely rotatable around one end of the reflecting plate. Since the reflecting plate is arranged so as to be rotated to a position where the filter is covered when optical communication is not carried out, the filter can be protected from being scratched or accumulating dust, and the unit can be made thinner. On the other hand, when optical communication is carried out, by rotating the reflecting plate, the communication direction can be set as desired.
