Abstract: An apparatus for mapping multiple lower-speed signal transmission frames to a higher-speed signal transmission frame. The apparatus includes buffers configured to buffer the lower-speed signal transmission frames, determination units configured to determine frequency justification information for the lower-speed signal transmission frames, a barrel shifter configured to receive signals output from the buffers, and a controller configured to control the barrel shifter to map the lower-speed signal transmission frames to the higher-speed signal transmission frame based on external settings for the respective lower-speed signal transmission frames and the frequency justification information determined by the determination units. When the minimum unit of the lower-speed signal transmission frames is a channel, the number of the buffers and the number of the determination units correspond to the maximum number of channels that can be multiplexed in the higher-speed signal transmission frame.

Abstract: An optical transmission system, where in an optical transmitter a detection bit having a specific pattern set according to the number of bits to be transmitted within one symbol time, is imparted with respect to a transmission signal in which transmission information has been encoded according to a preset format, and an optical signal generated by modulating light according to the transmission signal is transmitted to a transmission line. In an optical receiver, logic inversion or bit swap of received data is detected and compensated by using the detection bit included in the received signal, a decoding process of the compensated received signal is executed. As a result, when an optical signal capable of transmitting multi-bit information within one symbol time is transferred, it is possible to realize excellent transmission characteristics, by reliably compensating an error in received data caused by the modulation format or the multiplex system of the optical signal.

Abstract: There is provided topology information including connection states among nodes in a network, and port information including restriction conditions on connectivity among ports within a restricted node. A path search apparatus finds a first path having the minimum total link-cost among a plurality of paths. The topology information is changed so that the first path is not searched for as a path having the minimum total link-cost among the plurality of paths, and the port information is changed based on a port connectivity change rule. Then, the path search apparatus finds a second path different from the first path, based on the changed port information and the changed topology information, and reconfigures a pair of link-disjoint paths satisfying the restriction conditions imposed on the restricted node, by removing a link shared by both the first and second paths from the original topology information.
