摘要： An ATM switching system includes two ATM switches which are the same as each other. Each of the ATM switches includes a switch buffer, and a cell counter which indicates the number of cells in the switch buffer. Each of the ATM switches also includes a difference calculator, which calculates the difference between the number of cells in the two switch buffers when one of the ATM switches is changed from an out-of-service state to a slave mode. At this time, the other ATM switch operates in a master mode. Each of the ATM switches further includes a dummy cell generator, which generates a number of dummy cells which corresponds to the difference calculated by the difference calculator. The generated dummy cells are written into the switch buffer in the slave mode. When it is determined that when all of the dummy cells have been output from the switch buffer, the two ATM switches are syunchronized with each other.

摘要： The quality and performance of the connectionless communications system are improved. When a BOM is received, the destination address DA of the L3-PDU stored in the payload of the BOM is retrieved, and the tag information is obtained from the DA (S11). The output message identifier MID is reserved (S12), and the tag information and output MID are assigned to the BOM (S13). Then, the tag information and output MID are written to the table. When a COM is received, the tag information and output MID are retrieved using the MID of the COM as a key, and the information is provided for the COM (S31 and S32). When an EOM is received, the tag information and output MID are retrieved using the MID of the EOM as a key, and the information is provided for the EOM (S41 and S42). Then, the output MID is released (S43).

摘要： Recognizers are provided in respective self-routing modules in respective stages of a channel operating according to a multi-stage self-routing method. A recognizer sets a stage number to the switches in the self-routing module of the stage it belongs to by recognizing a stage number setting signal supplied from a self-routing module in the preceding stage. Updaters are provided in respective self-routing modules. An updater updates a stage number setting signal supplied from a self-routing module in the preceding stage and outputs it to a self-routing module in the succeeding stage. A stage number setter is provided in a virtual channel controller connected before a channel. It outputs predetermined stage number setting signals to a self-routing module in the first stage of a channel. Stage numbers specified by the stage number setting signals are autonomously set when the stage number setting signals sequentially pass through self-routing modules in respective stages.
