ABSTRACT:
A bridging apparatus is provided to connect Fibre Channel networks to an ATM network. The apparatus includes a Fibre Channel-link monitoring section for monitoring and detecting an abnormal event in the Channel Fibre networks; an ATM network monitoring section for monitoring and detecting an abnormal event in the ATM network; and a control section for sending, when necessary, an abnormal notification cell to said ATM network upon an abnormal event in either the Fibre Channel networks or the ATM network; starting an initialization protocol of the Fibre Channel links, upon detecting the abnormal event or receiving an abnormal notification cell from the ATM network; stopping initializing protocol of the Fibre Channel links until an initialization-complete cell is received from the ATM network during execution of the initialization protocol of the Fibre Channel links, sending an initialization-start cell to the ATM network; and, sending an initialization-complete cell to the ATM network, when an initialization-start cell is received from the ATM network after sending an initialization-start cells.
