| 摘要 |
The present invention is a fibre channel switch (300) employing a distributed queuing algorithm for interconnecting a plurality of devices (workstations, supercomputer, peripherals) through their associated node ports (N_ports) and employs a fabric having a shared memory (330) coupled to a plurality of fabric ports (F_ports) (305) through a bi-directional bus (312, 313, 314) over which memory addresses, frame data and communications commands are transmitted. Each F_port includes a port controller (310) employing a distributed queuing algorithm associated with a control network for communicating commands between the ports related to when and where frame transfers should be made, wherein the bi-directional bus provides an independent data network for access to the shared memory such that frames can be transferred to and from the shared memory in response to port controller commands.
