Switching Operation
The fibre loop switch implements the Fibre Channel Arbitrated Loop protocol. It provides concurrent connections to the storage area network (SAN) without changing the
The SAN operation changes dramatically when comparing a switch with a hub environment. The normal operation, as seen by a single
Figure 3: Switching Using Fibre Channel Protocol
The fibre loop switch maintains signal and data integrity by
As shown on the top of Figure 3, a Fibre Channel network has a physical loop structure. All traffic must go through all nodes. Since the physical media is shared by all nodes, the bandwidth must be partitioned between any nodes that
