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： An elastic store memory circuit includes first and second elastic store memories. Each of the first and second elastic store memories generates a phase comparison signal when a phase difference between a write timing and a read timing is within a predetermined phase range. The elastic store memory circuit also includes a selector which selects either the input data read out from the first elastic store memory or the input data read out from the second elastic store memory, and a slip signal generator for generating a slip signal on the basis of a write reset timing at which the first and second elastic store memories are reset, a read reset timing at which the first and second elastic store memories are reset, and the phase comparison signal. The slip signal indicates which one of the write reset timing and the read reset timing precedes the other one.

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.
