Abstract
A communication device having a plurality of processor units is disclosed. Each processor unit has a buffer for buffering packets, a receiving processor, and a transmitting processor. Upon receipt of a reception token, the receiving processor receives packets from the outside. Then, if the buffer is empty, the receiving processor buffers the received packets in the buffer. If the buffer is not empty, the receiving processor discards the received packets, increments the number of discarded packets, and passes the reception token to another processor unit for circulation. Upon receipt of a transmission token, the transmitting processor transmits the packets in the buffer to the outside based on the number of discarded packets.
