    摘要: In the master control unit, updated information is transferred to a slave control unit and a coherence of information between the master control unit and the slave control unit is periodically checked, thereby eliminating a difference of the internal information of the two units which execute a control, a status monitor, and a maintenance of a computer system in an on-line manner and guaranteeing the coherence. When the master control unit recognizes a difference between the information for a predetermined time or more, the slave control unit is halted and the information of the master control unit is made effective. With respect to an abnormality of the master control unit, the master control unit halts by itself. In this instance, the slave control unit is shifted to the master status and takes over the process.

    摘要: An optical packet transmitting/receiving system includes an optical packet transmitting apparatus for generating a copied optical packet signal of an original packet signal to be transmitted and for transmitting the copied optical packet signal after the original optical packet signal, an optical packet receiving apparatus for performing an error recovery processing based on the copied optical packet signal of the original optical packet signal, when an error occurs with the received original optical packet signal, and an optical packet switching apparatus. When congestion occurs between a copied optical packet signal inputted to an input port and an original optical packet signal inputted to another input port, the optical packet switching apparatus preferentially passes the original optical packet signal.
