Loop protection mechanism in fibre channel protocol?

Hi guys,

Is there a loop protection mechanism built into the FC protocol? Meaning, is it possible for an FC frame to loop endlessly between/within switches?

I'm new to fibre channel and am just starting to get my hands dirty with Brocade products. I try to relate concepts back to TCP/IP and Ethernet, and was wondering if there was an equivalent for STP. A brief summary or links to point me in the right direction would be great. I did try googling for this, but came up empty handed.

Also, if there is a good structured place to read up on FC theory, please let me know.

FC switchs implement Fabric Shortest Path First (FSPF) in order to find the shortest route to a destination and also it prevents loops from appearing within the fabric.

When it comes to reading material: BCFA and BCFP in a nutshell PDFs are a good entry point. You can find them in the following link:
