How is FC-AL implemented in loop switch?

This is a Q&A from SAN School Lesson 5.

From what I could draw from available sources is that loop switch as well as fabric one has a point-to-point, non-blocking architecture. How is FC-AL implemented in loop switch?
The switch provides a translation mechanism in a daemon running within the switch firmware. When an FC-AL device is attached to the switch port, the switch will assign a WWN to the FC-AL device based on an offset of the switch ports WWN. This way, each FC-AL ID also gets a WWN.
