摘要： A transmission system according to the present invention includes a transmission device and a reception device connected with each other via two lines. When the transmission device switches a line; used for transmitting VLAN traffic, from a first line to a second line, the transmission device transmits the VLAN traffic to the second line by switching the line after transmitting a post-switching message to the first line. The reception device includes a first buffer which stores the VLAN traffic received from the first line and a second buffer which stores the VLAN traffic received from the second line. When the reception device receives the post-switching message from the first line, the reception device starts reading of the VLAN traffic from the second buffer after reading the entire VLAN traffic stored in the first buffer.

摘要： A communication system 1000 has a communication path configured by connecting a starting-point device to an end-point device so as to be capable of communicating via at least one relay-point device. The communication system 1000 includes: a communication path determined band acquiring part 1001 that, for each of sections between communication devices adjacent to each other in the communication path, acquires a section available band, and acquires the smallest value between the section available band and a communication path request band that is a communication band requested for the communication path, as a communication path determined band; a band reserving part 1002 that reserves the acquired communication path determined band in the communication path; and a communication traffic controller 1003 that transmits communication traffic satisfying a traffic flow condition so that the communication traffic passes through the communication path where the communication path is reserved.

摘要： When a first communication device receives a predetermined message from a second communication device via a third line in a state of transmitting frames to a first line while performing error-correction coding on the frames, the first communication device switches the line to a second line after transmitting a frame of a post-switching message to the first line, and continues transmission. The second communication device receives the frames from the first and second lines and performs error correction, stores the frames, on which error correction has been performed, in first and second buffer, and when determining that it is necessary to perform line switching based on the status of error correction with respect to the frames received from the first line, transmits a predetermined message to the third line, and when receiving the frame of the post-switching message from the first line, starts reading of the frames from the second buffer after reading all of the frames stored in the first buffer.

摘要： Disclosed is a transmission system, having a transmitting device and a receiving device, which divides a series of data streams into a plurality of unit data and transmitting the unit data. The transmitting device and the receiving device includes synchronization units which outputs mutually synchronized clock signals. The transmitting device further includes a frequency change unit which changes a frequency of a time division multiplexing (TDM) signal on the basis of the clock signal output from the synchronization unit of its own device, and a conversion unit which converts the TDM signal with the changed frequency into the unit data and transmitting the unit data to the receiving device. The receiving device further includes a decoding unit which receives the unit data from the transmitting device and generating the TDM signal with the changed frequency, and a frequency restoration unit which restores the TDM signal by returning a frequency of the TDM signal with the changed frequency to an original on the basis of the clock signal output from the synchronization unit of its own device.
